2017 In Review

Typical storm front this spring/early summer headed for Stowe!

The 2017 golf season did not disappoint with any lack of storyline. When reviewing a golf season in the northeast the weather will always be the main topic. The months of May, June and July brought copious amounts of rain. This period set records with rainfall amounts and most continuous days with rainfall. The total rainfall for this three month period was 25 inches. Compare that number to the annual average rainfall in Vermont of 36 inches and you realize the abnormality. While rain is not good for playing golf, working in it is equally not good. I applaud the agronomic teams for pushing through all those days working in the rain. It became the norm to put your raingear on when leaving the house in the early morning and still have it on arriving home from work. Let's just say Gore-Tex and rubber boots were your friend!

Moving into late summer we experienced some great weather. When fall arrived it was the complete opposite of the spring. The fall period set a new record for the most continuous days without rainfall. It was great golfing and working weather. While drainage systems were important in the spring, in the fall the irrigation system became a crucial tool for great conditions.

White pine blow down next to 12 green

As to not disappoint before year end, Mother Nature unleashed a powerful windstorm on October 31st that caused significant damage in Stowe and surrounding towns. Stowe Mountain Club received very little damage from the storm. At Stowe Country Club it was another story. Many mature pine trees were broken in half and uprooted. Multiple pines lost large limbs and there was a massive amounts of tree litter that fell everywhere. There is no doubt we will be cleaning up from this storm well into the spring of next year.  I've been working on golf courses for close to 30 years and Mother Nature continues to be the one true challenge year after year. There are some years when she plays nice but there are just as many when she lets everyone know who is in charge.

Mark Finch, SCC Superintendent, dormant seeding greens

Even with the wet start both Stowe Country Club and Stowe Mountain Club continued to improve the turf quality and overall playability of the golf courses. It is our goal to always improve and never settle for average. I have always believed in the saying that "good is the enemy of great" and the agronomic team operates in such a way. Each golf course continues to improve by adhering to solid agronomic practices. The ongoing effort to topdress and verticut greens on a regular basis is crucial to providing smooth putting surfaces. Proper aerification practices continue to firm up the playing surface by removing thatch. Turf health is maintained through the use of best available nutrition and pest control products. One agronomic focus that continues at Stowe Mountain Club and Stowe Country Club is the push to grow and promote our creeping bentgrass populations. Creeping bentgrass provides a great playing surface on the greens and fairways. At SMC it is a matter of maintaining the existing bentgrass while at SCC it is about promoting bentgrass. A new process was initiated at SCC this fall to promote bentgrass on the greens. After the course closed for the year the greens were aerated with an eight inch deep solid tine then core aerated with a traditional 3/8 inch hollow tine followed by a topdressing with sand. After this process was complete a specialized seeder planted a high quality creeping bentgrass seed. This type of seeding is referred to as "dormant" seeding. The process involves the seed overwintering as seed and then germinating in the spring when conditions become conducive to growth. This agronomic practice will increase the bentgrass populations on the greens at SCC leading to a better putting surface in the long term.

Sean Hanley laser grading 15 tee tops

At Stowe Country Club, there were multiple projects that occurred this year. The biggest was the renovation of the fifteenth tee complex. This area had been overrun with white pine trees and the teeing surface was mounded due to years of divot mix accumulation. While local and regional contractors were used on the job much of the work was done by the SCC team. Myself, Mark Finch, and crew members worked tirelessly to get this job done on time for the Kirkwood tournament. Much of the work was done in ankle deep mud during the pouring rain. This in-house work included irrigation/drainage installation, sodding, cart path preparation, and finish detail work. In-house construction projects are difficult because of the effort needed to simultaneously stay on top of the routine course maintenance work. We did also rely on the expertise of two regional golf course contractors. NMP Golf  Construction provided a shaper to do the major site work. A good "shaper" is the key to any successful golf construction job. These bulldozer operators have the eye for how a golf hole should look and play. Sean Hanley from On-Course Golf came in for the final laser grading of the tee surfaces. Sean is the contractor that built our upper driving range tee. This new tee and fourteenth green surround has received much praise from the players. As the area matures it will become an even better playing experience. Thanks to all involved in a great project.

Renovation of 15 bunker

Other projects at SCC included the renovation of the second and fifteenth bunkers, four bunkers in total. These projects were completed by the SCC crew. It has been a priority in recent years to renovate a few bunkers every year. The reason for these renovations include poor drainage, continued washout of bunker sand, and loss of contours due to time.  The renovation process involves establishing new outside contour lines, removing old sand, shaping out new bunker floor contours, installing drainage if needed, and  adding new sand that is specified for bunkers. Additional projects included a new cart path on the fifteenth hole that complemented the renovation of the tee and repairing the cart path around the practice green at the clubhouse. The clubhouse landscaping was renovated. Much of the landscaping lost all interest due to over grown lilac trees. Finally, the irrigation pond was dredged.

Spectacular course conditions at SMC

While SMC was not as active with projects, the season was defined by superb conditions. The agronomic team headed by assistant superintendent Zach Fleeger pushed for championship conditions on a daily basis. We heard great comments from the members and players all season. The winter brush cutting done by Zach and fellow assistant Jerry Elliott on the fourteenth and third hole were well received and gave these two holes a fresh new look and feel. Look for more of this great work during the upcoming winter.

As we move into the winter season there are some great projects we plan to accomplish that will continue to improve the golfing experience at both Stowe Mountain Club and Stowe Country Club. I will update the blog through the winter to discuss these projects. Be sure to enter your email on the blog homepage for up to date blog posts. Thanks to all who made the 2017 a successful year on the golf course. All the best to everyone during this holiday season. See you on the slopes or someplace warm playing some golf!

Stowe Mountain Club Approaches

While night time temperatures are dropping and daytime humidity is somewhat disappearing, we know that the seasons are starting to change before our eyes. And even though we've had another tremendous summer, we are always looking to create conditions that provide the best golfing experience possible. This post will help describe how we do that on our "approaches" at Stowe Mountain Club.

My team has two primary focuses, health of turf, and playability for you the golfer. Increasing quality assists in providing exceptional aesthetics and playability helps you better enjoy your good, and maybe not so good, shots.

We have recently been giving added attention to the green approaches at SMC. The "approach" is a commonly overlooked facet of the golf hole because most golfers attempt to have their approach shots land on the putting surface - past the approach. But at SMC, with our small greens and backdrop of the mountains and trees, depth perception can sometimes be thrown off. Since we can't move mountains, we have opted to improve the surface where a great many shots are landing. By maintaining the approach, a greater variety of shots can be played from in front of the green.
At many courses the approach is maintained like a fairway. This means a higher (HOC) and less frequent fertility and turf treatment. While this may seem like an okay idea, in the long-term this frequently played -off turf can start to thin. At SMC, our focus is on providing golfers with many playing options, including putting, from the approach. With shorter cut turf, your approach shots experience no interference from the grass, giving you the ability to create more spin and control. And just like your careful shots around the green, our maintenance practices have to be handled with care. 

A look at the approaches being expanded back to the fairway.

Instead of using a typical triplex machine to mow the approach, we have employed a hand walk-behind mower. With this hand mowing effort, the attention to detail can increase immensely. The walk-behind can bring about it's own concerns, so for that reason we've provided some practices to offset these concerns. Walk-behind mowers require tight frequent turning in order to make the next pass. This tight turning can cause thinning and unnecessary wear on this short-cut turf. To offset this concern, we've started using turning mats for greens mowing and approach mowing. Whether it be for turning on the collars for a green or the primary cut for an approach, the turning mat allows for a firm place to turn. In addition, you may have even noticed that most of the approaches at SMC have been expanded out toward the fairways.

Using turning mats on the green surface while mowing hand mowing approaches.

We have also started topdressing more frequently. Expanding the lower height of cut (HOC), while advantageous for playability challenges the turf plant. The crown (heart) of the turf plant becomes more exposed with a shorter HOC. That is offset  with topdressing sand to insulate this crown. Even though the surface may seem more "sandy" immediately after its completed, with a few nights of overhead water and a day or two of mowing, this sand will settle right down to where it needs to be. However, insulation isn't the only reason to topdress. Topdressing also helps us achieve a decrease in thatch build up and an increase in surface soil porosity. This increase in porosity helps the root system maintain a consistent delivery of water and nutrients.

Ultimately, we are maintaining the approach playing surface more like a green. This new focus on approaches takes a little more effort to maintain, but with the right practices and the right focus in place, you will continue to see exceptional conditions at SMC!

Thanks for your continued support! See you on the course!

Stowe Country Club Irrigation Update

Twenty-first Century Irrigation... What is it?

Golf course irrigation systems consist of three major infrastructure components.  At Stowe Country Club, we recently completed an overhaul and upgrade of one of these components; the control system.  The pumping system and the delivery system are the other two.  The means to deliver water to the turf is one of the most valuable tools a golf course has.  The superintendent is responsible for managing water usage to yield optimal conditions of playing surfaces.  Executing this simple principle requires that the superintendent relies on all three major components to be flawlessly operable.

A basic approach to appropriate watering practices is simply to not over-water.  This is done for many reasons that include playing conditions, disease management, resource conservation, and more. It is crucial that watering occurs only when necessary and not only when convenient.  This brings to light the importance of the system and its components to be functional during crucial demand periods.

The irrigation system that is in use at Stowe Country Club is over twenty-five years old which poses great concern for possible failure.  We had the opportunity to upgrade the control portion of the system this summer. This is essentially the brain of the system and consists of a series of electrical field controllers that transmit electricity to each of the hundreds of sprinkler valves throughout the golf course to deliver water.  Using the seven former field controllers at SCC as stand-alone programmable controllers is an example of the most basic application of automated irrigation.  Until a week ago our assistant superintendent, Matt Jung, would make a visit to each field controller nearly every day and manually program the watering schedule.  This is analogous to setting 168 alarm clocks each evening but they cannot all go off at once, they have to be spread apart so as not to get so loud it wakes the neighbors.

Installation in progress

The pumping system has a maximum supply threshold of delivering 450 gallons per minute (GPM).  If there is too much overlap in the number of open valves that are demanding water during the nightly watering schedule, an alarm is activated and the pumps shut off before they are damaged.  The pumps will live to see another day but the irrigation schedule that was interrupted is now incomplete.  Most full watering cycles take 5-10 hours to run which is why an automated night time schedule is the only feasible run time.

The control system that we installed this July incorporates a central controller in the form of a computer that communicates to each of the seven new field controllers via radio frequency.  The central computer uses smart technology to schedule and facilitate the automated watering.  The central component creates a cycle schedule based on our daily parameters that maximizes the efficiency of the pumping system and its electricity consumption.  It monitors theoretical GPM flow in real time and adjusts watering in the field to consolidate running time while also avoiding overuse of the pumps.

(We anticipated this relocation and dropped a sleeve tube
underground to run wires through prior to cart path paving in May.)

The entire irrigation system benefits from this technology.  Knowing that all three major system components are aging and their reliability is questionable, we concluded that the smart features of the central control will help preserve the longevity of the system as a whole.  By prioritizing the control system upgrade we can confidently rely on the pumps to run at a more consistent speed or RPM, reducing wear and tear and reducing run time hours.  By maintaining a constant pumping speed and maximizing the demand of the available GPM flow, our underground piping system is moving a more steady flow and a holding a more static pressure level. Without central monitoring, water flow in the underground pipe can be variable and sporadic and can cause stress fractures and catastrophic breaks, especially in 25 year old PVC pipe.

Right: a screenshot of my cell phone utilizing an app that can communicate
with the central control computer remotely.

The control system is up and running and programming is as simple as a mouse click or as complex as we can fathom.  In an industry where water is a diminishing resource in some regions, it is our responsibility as superintendents to be conservative, efficient, and accurate in our watering practices.  There is an endless amount of data that we have begun uploading to our central control that will make our system operate optimally.  As we build our database we will begin to employ features of the control that communicate with our weather station to maximize water use efficiency.  For example, the watering schedule can be set to pause or end at the detection of rain.  The weather station will also feed data that measures the amount of evapotranspiration (plant moisture loss during day) and determine the amount of irrigation to apply to replenish vapor loss.  These are good examples of technology opening up a whole realm of new ways to increase accuracy and efficiency.  Not to mention, the ability to operate the sprinklers on the golf course remotely from anywhere in the world with our cell phones!

Winter Reflection at Stowe Mountain Club

While snow depths stayed low all winter season, the grounds department was able to prepare and complete some great projects on the golf course. It also halted the stress of true turf management, allowing our team to continue exploring opportunities to improve your golfing experience. Arguably, the winter months are some of the most important months for a golf course maintenance team. On the surface, it may seem like our main priority is only snow removal, but our scope of work extends far beyond. Refining the maintenance operation, analyzing the budget, and most importantly researching our team output on the property allows us to prepare for another successful golf season.

2 tee underbrush

Obstructed view on 18

This particular winter season, we identified 2 particular projects. Tees on holes 2 and 18 needed a facelift. Our goal was to improve turf health and aesthetic value. Like any project on the golf course, there is necessary research that needs to be completed before the start. On top of analyzing the budget, we make sure that the project will benefit the health of the surrounding turf. Most of the time the aesthetic value will also be immediately enhanced, but sometimes it may take a few weeks to a few months for the surrounding turf condition to also improve. As you'll be able to see during your round, our work significantly improves the aesthetic value of the holes. Over time, this work will also improve the health of the surrounding turf. The work on 2 tee opens up views to Peregrine Lake and the work on 18 opens up a view of "The Chin" on Mt. Mansfield and a beautiful rock face. The brush cleared on 18 tee also improves the playability from the black/blue tees (playing a right to left shot).

Cutting brush under 2 tee

Clearing underbrush this winter, particularly from tee surrounds, was an on-course priority. As I mentioned before, this particular act can help health and aesthetic value. By clearing brush, this will
dynamically enhance air flow and circulation. By enhancing these two things, the turf will have more sunlight and oxygen improving its ability to make more food for itself. Organically, the turf plant will also be able to improve its natural defenses, potentially decreasing overall pesticide usage.

Burning brush

We were then able to discard the removed brush by naturally burning. However, you will notice some standing "dead" trees remaining in the cleared areas. We refer to these "dead" trees as"snags." The "snags" are necessary in providing habitat for wildlife such as woodpeckers. The "snags" allow the woodpeckers to create cavities. These cavities allow smaller birds to occupy these spaces to nest called "cavity nesting." During this whole process we were able to partner with the Mountain Operation Team and borrow a tracked vehicle to access the golf course during the winter months. The sharing of assets between resort departments is really proving to be a valuable process for everyone involved. Sharing assets primarily helps the bottom line when analyzing the necessary inputs needed for these capital projects. This on-course winter work is very important because the forest will continue to grow in on the golf course, negatively impacting playability and aesthetic value.

A look at the final product

Thank you for your continued support! We look forward to your feedback regarding these winter projects!

Winter Work at Stowe Country Club

By Mark Finch, SCC Golf Course Superintendent

Winter Work

When we see a golfer or two walking the course course with a couple of irons and a pocket full of golf balls around Thanksgiving, it is a telling sign that winter in coming late. When we see the same people roaming the snow-less property on Christmas Eve is in confirmation that winter is late. Then to see people hitting balls and carrying a shag bag around the practice field after the New Year, we become skeptical of winter's arrival. 

So how does a winter like this affect the golf course in the spring? A quick recap of notable events:

• 66 degrees, December 24th
• 1 inch rain, December 30-31st
• (-10) degrees, January 5th
• 1 inch rain, January 10th
• 3 degrees, January 11th
• 54 degrees, February 3rd
• (-18) degrees, February 14th
• 1 inch rain, February 16th
• 5 degrees, February 18th
• 0.75 inches rain, February 20th 

Ice formation on the turf is the conditions we are most concerned about in our region as it pertains to the winter turf survival. The other condition is called crown hydration. This is the harmful freeze-thaw pattern that the turf is susceptible to while breaking dormancy in mid-March and early-April. These fluctuating extremes are notable but not that unusual. The sequence in which these events take place is what requires close attention. Basically, the recipe for disaster (in our case, ice formation) is a winter rain event immediately followed by single-digit temperatures. We observed this pattern three times so far this season. Fortunately, in the case of the December rain, the ground had not yet frozen so the rain was absorbed throughout the soil. The subsequent events occurred in mid-January/February and there was a large amount of ice. From a glass half full perspective we had a couple factors on our side at that point; barely any snow and it was already mid-February. Turf can withstand a certain amount of time under ice cover. Creeping bentgrass has an ice tolerance of 90 days and Poa Annua has a tolerance of only 30-60 days. Having a mixed stand of both of these grasses at SCC causes concern for any length of ice cover. This February icing events puts us in the better scenario for survival due to the shorter duration under ice. Turf damage occurs from ice coverage due to the low levels of oxygen and the accumulation of exhausted gasses that can be fatal to turfgrass. 

It is almost inevitable that every winter comes with a January (or February) thaw. As noted, on February third we reached fifty four degrees which typically would have melted a lot of snow. But with hardly any snow on the golf course to melt, it was the ice that was melting. By the end of that week Stowe Country Club was approximately ninety percent void of ice and snow. 

Digging Dry Well On 18 Green

We are not in the clear yet. The scariest days of winter are still to come for golf course superintendents in northern climates. The days and nights of freeze-thaw, or crown hydration potential, occur in mid-March through early-April. Essentially, the plant may begin to take on water during a thaw and then freeze at night. The cell structure of the plant becomes swollen with water and when this water freezes the cells expand to the point of rupturing. This rupture occurs in the crown, or growing point, of the grass so the plant becomes injured. 

We do everything we can throughout the winter as superintendents to intervene and mitigate any conditions that may be conducive to either of these types of winter associated injuries. Timely snow removal to hasten ice melt, drainage improvements to facilitate standing water and plant protectant applications are some examples of countermeasures we routinely execute before winter arrives and as the snow melts. Invariably, there is always the possibility of some amount of turf loss due to the unfavorable winter conditions. As for this year, we are closing in on the point where we can rule out much possibility of significant ice damage due to length of cover.

Adding New Sand at 18 Bunker

Our staff took full advantage of the extended period of mild weather that occurred well into the month of December. This "bonus" time was used to aerate fairways and rough along with facilitate a few drainage projects and bunker improvements that were scheduled to take place in spring 2016. Golf course improvements and repair that began after the golf course closed for the season include:

• Both greenside bunkers renovated on hole 18 (completed reshaping, new sand and internal drainage)
• Fairway/Rough internal drainage on hole 13 (piping and surface drains installed and ready for spring regrassing) 
• Leveling and resodding of back tee on hole 10

There is no question that drainage infrastructure is lacking at SCC but our progress is reaching a  point where noticeable improvement is being made. We plan to continue addressing poorly draining ares of the golf course in the early spring and again in the fall of 2016. Our efforts are focused on fairways and bunkers. Enhancements in our cultural programs on greens has paid great dividends with the drainage performance and playability of the putting surfaces. We will continue to institute new practices to sustain the progression this year. 

Repairing Drainage 18 Bunker

During the month of January we resumed implementing our tree management program. For a period of time we had just enough snow to get on on the course with our tractor to conduct tree work. There are a growing number of tree specimens on our property that are diseased and hazardous. We specifically identified an area between the twelfth and thirteenth holes where spruce trees had matured to the point of die-back and became diseased. The selective removal of these trees will better enable us to safely recapture the beauty in this vast rolling space as a fescue area with desirable trees featured. A similar renovation took place between the fourth and fifth holes. The species here were northern white pines of the "pasture" form. After assessing the unnerving growth habits and health of this stand we prioritized reclaiming this tract as well. The completion of work at this location will introduce expansive views of the golf course as well as the scenic view of Camel's Hump from the fourth tee and green. We are excited to be finalizing the revitalization of the fourth hole through the completion of several projects over the past few years. These efforts include: 

• Tree removal and fescue grass establishment, left side 2013-14
• Tree removal and fescue seeding right side 2014-15
• Cart path relocated and paved, tee to green, 2015
• Mounded fescue features, right side, 2015
• Bunker shape restoration, new sand, 2015
• Tree removal, fescue restoration, right side, 2015-16

Golf Maintenance Staff Re-assembling SMC Tent

At this point in February we feel the golf season fast approaching and there is still a lot to do. There are golf course accessories to refurbish for another season and a fleet of grounds equipment that we overhaul, service and sharpen to be ready for heavy use during the golf season. We are fortunate enough to house all of our equipment under shelter this year for the first time ever with the addition of a temporary structure that we re-purposed from Stowe Mountain Club. We were able to erect the structure ourselves just in time before the first snow. 

When the golf ends for the year our efforts to maintain the course do not end. In fact, some of our most productive work is conducted in the off season. With another winter flying by, we continue to work hard preparing for another great golf season at Stowe Country Club.

 

The Fall Push

The golf season may have ended at the resort but the work on the golf course continues. Both golf maintenance crews are busy with chores to put the courses to bed for the winter. The challenge this time of year is the unpredictable weather and not knowing when winter conditions will finally arrive.  Our goal is to have all winterization chores done by the second week of November.

Draining spring on  11 approach

When the courses close our first task is to bring in all items on the course that are not anchored to the ground. These items include tee markers, flags, benches, hazard markers, bunker rakes, ball washers, etc. These items are thoroughly cleaned and stored safely for the winter. Tree litter clean up is constant in these last few weeks. Whenever conditions allow we will clean up leaves and pine needles. The irrigation systems will be cleared of water using compressed air. Close attention is paid to this chore because an improperly blown out system will lead to broken pipes or irrigation heads in the spring. After the system is clear of water the pumps are dismantled for the winter.

This time period on the golf course is ideal for drainage projects. Multiple drainage projects have already been accomplished and are still under way. At Stowe Mountain Club (SMC), three springs that popped up during the very wet June were fixed. Due to the mountainous terrain, springs will pop up over time as the groundwater moves through the underlying soil and exits at the surface. These spring diversion projects were done on eleven approach, sixteen approach, and eighteen white tee. A large drainage project was also completed between seven tee and 8 fairway. Due to the proximity to the dam, this project was contracted out and was supervised by an engineer. We will be sodding this area in the coming days so that it will be ready for play on opening day next year.

At Stowe Country Club (SCC), we are close to completing the bunker restoration on the eighteenth green. These bunkers had grown in over time and water would puddle in the bunkers after rain event. These bunkers were re-contoured to the original shape, drainage was installed, and new sand was added.

SMC, Applying Wintergreen to greens 

Finally, in preparation for the long winter we implement multiple preemptive measures to help the turfgrass survive.  If you ski during the early season you may notice that the greens at SMC are a vibrant green color. This is due to a paint that is applied to the putting surface for winter protection. This product is called Wintergreen and is a combination of a latex paint and anti-transpirant. The logic behind this application is that it protects the turf from severe wind damage, will prevent disease controls from degrading, and will help the soil warm up in the Spring due to the dark green color. After painting the greens we will lay a protective mat in areas that experienced prior winter damage. This mat is called Enkamat and has proven to prevent ice damage. We will then cover the entire green with a breathable cover on eight of the greens. These greens are covered because they get windblown and do not get the protective snow cover. Some of the same measures are implemented at SCC, but not all.

If you get a chance to enjoy touring the course this winter please stay off of the greens. Packing the snow on the green will cause icing which can kill turfgrass. We will rope off all the greens to identify the location of each green. Both golf maintenance teams hope you had an enjoyable 2015 golf season. We are already preparing for another great golf season in 2016.

Pure Stands

Maintaining pure stands of desirable turfgrass on our golf courses is the ultimate agronomic goal. The desirable grass on greens and fairways is creeping bentgrass.  On tees at Stowe Country Club (SCC) the desirable grass is creeping bentgrass. At Stowe Mountain Club (SMC), the tees are a mixture of Kentucky bluegrass and fine fescue. The rough at both golf courses is also the mixture of Kentucky bluegrass and fine fescue. Finally, the desirable grass in the no-mow high grass areas that sit on the edge of golf holes is a blend of fine fescues. At SCC, while creeping bentgrass is most desirable, the fine fescues are considered desirable in all playing surfaces except greens.


The purpose of this goal is based on playability. When multiple different grasses or weeds populate a playing surface ball roll and shot making are both negatively impacted.  On greens, pure stands of creeping bentgrass is desirable because it will provide the smoothest ball roll. The creeping nature of the bentgrasses allows for the ability to mow at low heights of cut. The non desirable grass that we manage against is Poa annua or annual bluegrass. Poa annua is present in the greens at SCC but not at SMC. In the spring, the Poa annua will produce a seedhead which in turn makes for a very bumpy and irregular putting surface. Additionally, Poa annua is not as tolerant to stresses as bentgrass is and will decline in the summer and winter if conditions become severe.

On tees, the two golf courses differ in the desirable grasses but the purity of the turf is still important. Weeds such as crabgrass are kept at bay because of its coarse leaves that produce an uneven surface. Poa annua is considered a weed on both sets of tees because of it's clumpy growth habit. The interesting aspect of our tees is that while creeping bentgrass is the desirable grass at SCC it is considered a non-desirable grass at SMC. The bluegrass/fescue mixture was chosen for tees at SMC due to it's low maintenance costs and durability. Creeping bentgrass has invaded the teeing surface and is now considered a weed on tee surfaces. The bentgrass got into the tees during construction. The bentgrass seed is very small and subsequently was tracked onto the tees from the shoes of the construction workers and was in poorly cleaned drop seeders. As time progressed this aggressive grass has spread. Removal of this grass is needed because the blotchy nature of the bentgrass patches can be distracting to the eye and the feel underfoot is completely different from the bluegrass/fescue mix. Additionally, the agronomic requirements for bentgrass is different than bluegrass/fescue making proper management a challenge.

Pure Creeping Bentgrass #7 Fairway at SMC

On fairways, creeping bentgrass is the best possible playing surface. Kept weed and Poa annua free, a pure bentgrass fairway provides the best possible shot making experience.

In the rough areas, bluegrass/fescue mixtures are the most desirable grass stand because of the upright growth habit. This growth habit props the ball up providing a good lie. Broadleaf and crabgrass weeds can present a problem if the populations are too high causing difficult lies.  As with the tees at SMC, creeping bentgrass is considered a weed in rough areas at both golf courses. The reason for this is that when bentgrass is mowed at rough height of two and a half inches, the bentgrass becomes very puffy. Playing out of a bentgrass rough is difficult because the golf ball settles deep into the puffy bentgrass and the grass will grab the golf club causing errant shots.

In the no-mow areas the fescue grasses are the desirable stand of grass. The fescues have a growth habit that allows for the golf ball to be found and advanced even when the grass is left to grow high and seed out. These fescue areas provide a look to the golf course that is very aesthetically pleasing, especially when the grass turns brown. Weeds and pasture grasses must be kept out of these areas because finding and hitting a ball out of non-pure stands of fescue is very difficult resulting in errant shots and slow play.

The strategy to accomplish the goal of pure stands is varied. When it comes to growing pure creeping bentgrass there are some basic rules. The timing of aerification is very important. Both SCC and SMC greens were both recently aerated because late August and early September is the best time for this. The reason for this is that Poa annua will not germinate when the soil temperatures are warm. Aerating in April and October is avoided due to the cool soil temps and the possibility of increasing the Poa annua populations when the putting surface is opened up due to aeration. The aeration is necessary to maintain proper organic matter and thatch levels. When bentgrass gets too thatchy it can begin to thin and weeds will encroach into the stand. Specific growth regulators are used to promote bentgrass growth and discourage Poa annua growth.

Creeping Bentgrass Turning White On #12 Tees at SMC

Maintaining pure stands of Kentucky bluegrass/fescue is accomplished through the used of different herbicides. The broadleaved and crabgrass weeds can be easily controlled on an annual basis. The more difficult "weed" is creeping bentgrass. The same characteristics that make bentgrass a desirable grass in some areas is the same reason why it is difficult to remove from bluegrass/fescue stands. The aggressive and resilient characteristics of the bentgrass calls for multiple herbicide applications to remove this grass. Currently, at SMC we are in the process of removing the bentgrass from the back nine tees. The product used to remove bentgrass attacks the chlorophyll producing mechanisms of the plant causing it to turn white and eventually starve to death. Ultimately, to maintain a pure bluegrass/ fescue stand we need to produce healthy turf that will crowd out any undesirable weeds.

A Pasture Grass Plant Amongst a Pure Stand of Fescue

It is challenging to maintain pure fescue stands because of the fact we only mow these areas once per year and mowing itself is a method of weed control. The best way to maintain pure fescue is to burn these areas every year. Unfortunately, open field burning is banned in the Stowe, VT area. As a result of not being able to burn we apply herbicides that reduce the weed and pasture grass populations. Often times we will hand pull weeds if the populations are small.

Maintaining pure stands of desirable grasses is our goal. How we get there is multi faceted and often challenging. Once this goal is obtained the playability of the golf courses is improved and the enjoyment of the game is increased.

 

Stowe Country Club Update

General
The weather was once again the biggest challenge over the past month. The month of June brought over ten inches of rain to Stowe Country Club. In May, we battled the extreme lack of rain and now June was the complete opposite with record setting rain totals. This "new normal" of extreme weather patterns is reality and how we prepare to overcome these challenges is the difference between success and failure. The heavy rains were a good test for the new fairway and bunker drainage. These new drainage projects performed very good and we will continue to address other wet areas by installing more drainage.

Squeegeeing greens before Kirkwood Tournament

Kirkwood week was a challenge due to the rain. The days leading up to the event brought significant rainfall. The crew spent all day Wednesday before the tournament squeegeeing water off greens. Our sixth and final round of pushing water came as the sun went down. These efforts allowed for firmer greens for the first three days of the event. While Sunday ended in a rain-out, I am very proud of our crew's effort in preparing for the tournament.

Greens
The winterkill spots have grown in very well. The repair would have been much quicker if it was not for the excessive rain in June. These areas were damaged in the winter due to the fact that they puddle with water and then freeze. The nature of these areas to puddle made it difficult for the seed to establish because of being submerged under water and being constantly washed away. As the Kirkwood tournament approached the excessive squeegeeing damaged some of the seedlings setting the recovery back even farther. Mark Finch, golf course superintendent, did a superb job with the re-establishment of these areas. Mark worked diligently on a day to day and hour by hour basis for two months to get these damaged areas back to full turf coverage. Growing in turf on established golf greens is very difficult due to the ongoing maintenance of the surrounding turf and golfer traffic.

Root pruning at 15 tee

Tees
There were some recent changes to the fifteenth tee. The granite tee marker and bench were moved to make room for a root pruning operation. The close proximity of this tee box to the row of white pines negatively impacts the turf quality due to shade, needle shed, and root intrusion. The shallow rooting of white pines steals water and nutrients that is needed by the turf. Root pruning cuts the tree roots before they intrude into the teeing ground. We use the drainage trencher that was purchased last year to shear the roots. This process is an annual maintenance activity that will help the fifteenth tee recover faster from divoting and wear.


Fairways
The big push on fairways has been to achieve one hundred percent full turf coverage. The crew has been diligently seeding and sodding thin areas. Most of the damage is from poor drainage. Low areas on three, five, and twelve have had chronic thin areas. This is unacceptable for myself and staff. We will continue to sod and reseed until we reach full turf coverage in fairways.

Projects
The revitalization of the fourth hole is nearly complete. Multiple issues impacting the quality of this par three have been addressed. The over planting of trees on the left and right side of the hole blocked the view of the entire green complex and limited the use of the teeing ground due to blocked shots. A dozen trees were removed over the past two winters opening up the view of the green with surrounding mountain ridge line and providing full use of the tee. The fescue grasses that existed under the trees have come back to life and now provide a stunning framework to this hole. The cart path running along the right side was damaged in multiple sections, was too narrow for maintenance vehicles, and was positioned in a way that impacted the look of the hole. The path was repositioned and is now hidden from view. Slight mounding was added to aid in blocking the view of the cart path. Fescue was then planted along the new path to add additional screening of the path. As the fescue grass matures on both sides of the hole it will provide a stunning look to this great par three. The path is scheduled to be paved this week. Finally, the bunkers have been aggressively edged to bring back the original shape and add a better visual from the tee box. New sand was then added to provide consistent shot making.

The Spring Hustle

   As May has come to a close, it is a good time to review the condition of the golf courses and discuss the projects that have occurred. The variability of the Vermont spring is always a challenge for golf course maintenance. While planning operations is essential, it is even more important to be able to react quickly to unexpected challenges.

    The biggest challenge this spring has been the dry weather. While recent rains have helped, early spring rain did not occur. The successful start up and operation of  both irrigation systems has been of extreme importance. As the turf completes its winter dormancy and begins to grow, the need for water is crucial to initiate growth. While it might be hard to believe, early irrigation in May is crucial for positive turf growth. Turf is grown in sand based systems that can lose moisture quickly. In addition, the closely mown turf is very susceptible to moisture loss. Compounding the challenge of irrigating in a dry spring, a deep frost layer caused an above average number of breaks in the irrigation system piping. The turf care teams have been hustling to repair these breaks so that irrigation can continue.

damaged areas.

    Stowe Mountain Club (SMC) and Stowe Country Club (SCC) courses were impacted by winterkill this spring. The two reasons for winterkill this year were crown hydration and wind desiccation.  Stowe Mountain Club received desiccation damage on the first tee and sixth green. Those two areas were impacted due to the exposure to the severe north winds in the winter. In my eleven years at Stowe Mountain Club, I have never seen these levels of wind desiccation damage. The damage occurs due to the severe winds simply drying out the above ground tissue of the turf. Most often the turf can withstand the winter winds, this year the extended cold weather coupled with high winds pushed the turf to the extreme limit.

    This spring both courses were impacted by crown hydration. Ideal turf growing conditions during spring thaw requires sufficient surface drainage preventing standing water. Crown hydration occurs when night time temperatures drop below freezing. The cells in the turf plant will explode due to the freezing standing water. The common theme with this type of damage occurs in chronic wet areas. Stowe Country Club experienced crown hydration on the greens of one, nine, thirteen, and eighteen. At Stowe Mountain Club the damage occurred in the low lying areas of the fairways. The worst of the damage at SMC was found on eight and twelve. The turf care teams have seeded the damaged areas and positive germination has occurred. Full coverage is expected by the end of June. In reviewing the best options for damage prevention in the future, the installation of sub surface drainage to these wet areas will significantly reduce the potential for crown hydration.

    Currently, the Stowe Mountain Club crew is wrapping up a couple drainage projects that were initiated in the late Fall of 2014. The hillside on the eleventh hole had drainage installed to firm up the slope due to springs emerging through the turf. These springs were captured and piped through the fairway. The fourteenth fairway had drainage installed to help prevent winter damage and help firm up the fairway after rain events. These projects are in the final stages of completion.

    At Stowe Country Club a large key culvert was replaced in the practice field. The old pipe was made of metal and was rusted out creating multiple sinkholes holes in the field. Coupled with this project is the addition of target greens in the practice field. When completed there will be four greens for players to hit at. These greens will replace the current poles. The design of these target greens is such that they are raised slightly above the field and the top surface will be mowed at a short height. This raised angle and low cut will provide a larger target for players to aim at and improve their game. Two of the four greens have been shaped and seeded. the other two are still under construction. As an added visual aesthetic, there will be pseudo bunkers placed in front of these greens. These features will look like bunkers but will be built in such a manner that mowing and picking balls will not be extra maintenance.

    Finally, a project was completed at the SCC maintenance facility that has revolutionized how the turf care team  conducts business on a daily basis. A new equipment wash pad was constructed away from the fourteenth tee box. Prior to this new wash area, all equipment was washed directly adjacent to the tee box. The subsequent activity and smell of decaying grass clipping significantly impacted the golfing experience. The new location is on the other side of the road out of site of the public and golfers. The construction of the wash area is such that grass clippings can be managed properly reducing the odor and the water runoff is treated using a natural buffering system. Maintaining great golfing conditions starts with effective, efficient, and safe working conditions at the maintenance facility.

    While the dry May weather has presented some challenges for the grounds staff, the dry firm conditions have been excellent for golf. I hope everyone has had the opportunity to get out and play. Our two golf courses are very close to rebounding from winter and will soon be in top form. Thank you for your patience and assistance while we continue to maintain and improve the golfing experience at Stowe Mountain Resort.

A Short Look Back and a Long Look Forward

The 2014 Golf Season was defined by the epic level of turf injury that occurred from the severe winter weather of the "Polar Vortex". Widespread turf loss was reported throughout the Northeast and Canada. Unfortunately, six greens at each of Stowe's courses experienced some type of turf loss. The areas that experienced the most damage were greens seven and thirteen at Stowe Mountain Club (SMC) and twelve and thirteen at Stowe Country Club (SCC). Fairway damage was also significant at each course. While many golf courses suffered for months with visible damage it was hard to find any damage on either of Stowe's courses by late June. The hard work and diligence of both crews  is commendable.

Late Fall of 2014 was a productive time at SCC with focus on drainage, infrastructure repair, and tree management. Most projects on the to-do list were completed with exception being the repair to the green-side bunker on the ninth hole. Completed was the repair to the bunker on one green and the fairway bunker on eighteen. Good sand and new drainage were installed, and the bunkers will play and look better in any type of weather. The re-contouring of the bunker on eighteen provides an important architectural feature-the hazard is now visible from the tee.

Last season a tremendous amount of work went into improving the drainage at both courses. "Slit drainage" was installed in multiple areas. Slit drainage utilizes a unique two inch pipe that is back filled with straight sand. This design has proven its success on our clay based soils. The fairway drainage on nine and eighteen will now allow for firmer playing conditions especially during extended wet periods.

  

Installing Drainage SMC 14 Fairway

The unique location of the SMC course provides a challenge for turf survival due to the length and intensity of the winter weather. We are continually developing new methods and practices to prevent winter kill. Keeping the playing surfaces free of standing water is paramount to good in-season playing conditions and winter survival. At the SMC course, fairway drainage work was initiated on eleven, fourteen, and fifteen. Many of the new drainage lines were left open for the winter to assist in water movement during the spring thaw. These areas will be recovered before opening day. 

This winter we have been busy with the continued implementation of the SCC tree management program. For more information and to review this program, read the blog posted on 5/11/14. As it was last year, the focus this winter is on damaged trees that pose a safety hazard and trees that are overgrown and impacting play and the aesthetic of the course.

Golf is a game of options. Many of the trees found next to teeing grounds force the player to play only one type of shot. Opening up the tee shot to multiple options is a sign of a well designed golf course. For example, two white pines were recently removed from the ninth tee. These two white pines forced play to the left from the white and blue tee box. From the back tee, the tee shot was exceptionally narrow due to the overgrown canopy. Players now have the option to draw or fade the ball into the landing area. The next trees to be removed will be the white pines behind the sixteenth green. These four trees have been damaged by the violent storms that have rolled through the area in the past decade. The interior of the trees have signs of rot and are deemed hazardous.

From an architectural perspective the number sixteen green sits atop a beautiful rise that provides a panoramic view. It is a common misnomer that all golf greens need some type of backdrop for the purposes of "framing". While in some cases a frame provides focus and depth, in others an open sight-line behind a green can also provides an exciting challenge for golfers. In researching the course history the architect, William F. Mitchell, did not intend for this particular green complex to have a backdrop of trees. As a result, no replacement plan is in place once these damaged trees are cleared.

The Stowe Golf Agronomic Team is excited for the upcoming 2015 golf season and we hope the winter weather is as good to the golf courses as it has been to the skiers and riders. While we continue to enjoy the winter season, we will continue working hard at both Stowe Country Club and Stowe Mountain Club.
