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!

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.

 

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.

 

A Work In Progress

    Golf courses are in a perpetual state of decline. It is no different from any other manmade object. A house, a car, or a road will eventually need some type of maintenance activity to keep it performing and looking good. Additionally, due to the fact that golf courses are a living and breathing (respiring actually) thing they can also be compared to human health. When neglected, the body and mind will decline at a faster rate than one that has had preventive health care and proper nutrition. Providing the golf course with proper nutrition, preventive treatments to ward off pests, removal of excess thatch, repair of failed infrastructure, and proper tree management ensures its long term health.

    While the term "a work in progress" often refers to a situation that needs work to become good, in the golf course world, it refers to the concept that the act of continual work is paramount to the future health and playability of the course. The simplest example of such work is aeration. The Mountain and Village course greens are two to three weeks out from a hollow core aeration. While the greens are a bit bumpy in the immediate days following aeration it is the long term health and performance of the greens that need focus. The removal of thatch and organic matter through hollow core aeration prevents soft greens that footprint easily and become bumpy, stay wet for extended periods, are more prone to disease, and become more susceptible to winter injury.

   The more complex work is the revitalization and repair of golf course features. Such work includes drainage repair and installation, repairing damaged cart paths, tee top leveling, re-contouring of bunker edges, and tree work. Some of this work occurred this Spring while other work will occur this Fall.

Stowe Mountain Club

• Continued aeration. Fairway aeration is ongoing. We are currently half way through this process. With

  

  Fairway aeration and clean up

  good weather this process will be complete by next week. Tees and approaches will follow and only take a couple days to complete.
• Drainage on the right side of eleven fairway. This hillside is crucial to the playability of this hole. Tee shots that hit the hill stand a good chance of rolling back to the fairway. Due to some groundwater springs, this hillside is often soft and impedes the ball from rolling to the fairway. 
• Extend drainage in fourteen fairway. Last Fall, a main drain line was installed near the landing area. The main purpose of this line is to alleviate chronic winterkill caused by excessive wet turf during snow melt. The installation of this drain line was successful in limiting the amount of winterkill this Spring. This line will be extended and laterals will be installed to further eliminate the potential for winterkill.
• Fairway drainage on fifteen fairway. As with fourteen, this fairway succumbs to winterkill due to wet conditions during snow melt. Drainage will be installed to assist with winter survival.
• An ongoing project is the repair of a ground water spring above the first landing area on the eighth fairway. Due to the proximity to the dam, this project has been a slow and deliberate process. The design to alleviate this chronic wet spot has been highly engineered and managed. A subcontractor is currently being secured to finish the project. 
• New forward tees have been built on the third hole and eighth hole. The third hole tee is now open. The eighth tee was constructed from the spoils of the previously discussed wet spot on eight. This tee has been seeded and will open Spring of 2015. 
• Fescue has been planted along the stone collar on the ninth hole.
  

  
  

  

  Collar extension on #9

  This work also used the spoils from the drainage project on the eighth hole. Planting fescue along the edge of Peregrine Lake softens the look of the stone and allows for additional playability to mis-hit tee shots.  
• The collar on the right side of the ninth hole has been extended. This collar extension was done to aid in the approach shot bouncing to the left and landing on the green. Collar extensions similar to this work have been installed on the sixth, eighth, eleventh, and thirteenth. These creeping bentgrass collar extensions are done to assist with better playability around the greens. 

Stowe Country Club

• Tee aeration is complete. Fairways and approaches will be aerated after Stowe Mountain Club is complete. All of the aeration equipment is shared between both courses. Aeration at Stowe Country Club is very important because of the heavy clay soils that exist under all the features. Alleviating soil compaction and increasing surface drainage is part of the ongoing work that promotes healthy turf and good playability in all weather conditions.
• A new culvert pipe was installed at the practice facility field. This pipe transfers water from a stream that enters the field on the west side. The existing pipe was an old metal pipe that had completely rusted and caved in. Prior to the installation of the new pipe being, water would flow onto the field and pool up for extended periods of time.
• A new culvert pipe was installed on the thirteenth hole. This pipe had completely failed like the one on

  

  Silted bunker on #13

  the practice field. During the Winter melt, the pipe collapsed and silted in the greenside bunker. The pipe was replaced and the bunker was also repaired. New drainage was installed in the bunker along with all new sand being added. 
• New forward tees have been constructed on the sixth and ninth holes. The ninth tee opened recently and the sixth tee may open in a few weeks if the weather provides good growing conditions. 
• The final step in drying up the seventh hole was completed this Spring. The wetland to the left of the landing area was leaching water through the soil creating chronic wetness in the fairway. An interceptor drain was installed to divert this water away from the fairway. 

  

  Repaired #13 bunker with drainage

• The new upper practice tee was opened during Kirkwood week. We doubled the size of the tee surface, moved the ball machine away from the road, eliminated a small practice green and bunker that had gone into disrepair, and provides a new staging area for carts during tournaments and outings.
• This Fall, we plan on repairing multiple bunkers and fairways. These projects will commence immediately. The order of completion is as listed below.  

• Multiple laterals will be installed on the eighteenth fairway. This work was started last Fall by installing a drainage mainline. We will connect multiple laterals to this mainline in the coming weeks.
• The fairway bunker on the right of eighteen will be re-contoured and drainage will be installed. This bunker has grown in over the years and pools up after rain events.
• A mulch bed will be installed underneath the spruce grove on the left of eighteenth hole. This work will be done to provide definition to the landing area and to protect the future health of these trees.
• The greenside bunker on the first hole will be repaired. Currently, water leaches out of the bunker and settles near the approach. This area has turned into a chronic wet area that is very difficult to play out of. Additionally, the general appearance of this area is very poor and should be corrected because it sets the tone for the entire golf course. Internal drainage in the bunker will be installed to transfer the water away from the playing area and new sand will be added.
• The second half of the ninth fairway will be drained and the greenside bunker will be repaired. This fairway does not drain after rain events. A main line will be installed with multiple laterals. The bunker will be re-contoured to divert surface drainage away from entering the bunker, internal drainage will be installed, and new sand will be added. 

    All of this work is being done with an eye on the future. The short term disruption to play is done for the long term goal of the continued enjoyment of both golf courses by the members and players. This continued enjoyment is based soundly on the hard work of the maintenance team and the commitment of Stowe Mountain Resort to provide great conditions.  We thank you for your patience and understanding while all of this work is in progress. 

 

Bentgrass

Bentgrass is the preferred turfgrass on fairways and greens in the northeast. The ability to tolerate low cutting heights, aggresive lateral growth habit, dense canopy, and stress tolerance make it a suitable playing surface for the game of golf. The predominant species of bentgrass is creeping bentgrass. Within this species there are hundreds of cultivars. The breeding of creeping bentgrass is a very competitive business due to the golf course industry. The other type of bentgrass is velvet bentgrass. This bentgrass had its hayday in the 1950's and 60's on golf courses. It is an old variety of bentgrass and existed before many creeping bentgrasses were bred for golf turf. Since that time creeping bentgrass has surpassed velvet bentgrass as the preferred golf course turf.

Graden cultivation

We manage both courses in a manner that promotes bentgrass. We do not simply grow "grass". Our mission is to promote bentgrass growth and overtime increases its population on greens and fairways. Stowe Mountain Club has A4 creeping bentgrass on the greens and L93 creeping bentgrass on the fairways. These two grasses were chosen by Billy Fuller from Bob Cupp Design, the golf course architect. Billy was the Agronomist for Bob Cupp during the construction of the course. The interesting story behind A4 is that Billy worked with Dr. Joe Duitch from Penn State to breed this specific cultivar. While the superintendent at Augusta National in the early 1980's, Billy showed Dr. Duitch a patch of bentgrass on the par 3 course that exhibited a very tight and smooth growth habit. From that patch the A4 bentgrass was bred to be what it is today. It is one of the premier bentgrasses for putting greens in the world. The "A" stands for Augusta. The L93 bentgrass in the fairways is also a newer cultivar. It is considered a workhorse in the golf industry. It is a very versatile turf that can also be used for tees and greens. The tees at the Mountain Course are not bentgrass but rather a blend of chewing fescue and dwarf Kentucky bluegrass.

Core aeration cultivation

Stowe Country Club has a much more diverse mix of turf species. The greens are a mixture creeping bentgrass, velvet bentgrass, and annual bluegrass. Many of you know annual bluegrasss by its scientific name, Poa annua. This mixture of grasses creates a very challenging scenario for reaching the goal of smoothness. You can identify velvet bentgrass by it's very fine leaf blade, dense growth habit (looks like moss) and it's soft puffy feeling under foot. It is also visible on the greens due to its round patchy growth. In between these velvet patches is Penncross creeping bentgrass. Unlike A4 and L93, Penncross is a very old cultivar. In fact, it is considered one of the first cultivars of creeping bentgrass. Pencross has been around for many decades and can still be purchased to this day. Pencross is known for its aggressive creeping or lateral growth habit. This can be viewed as a positive aspect due to its ability to creep laterally to fill in any damaged area or divot. However, on greens it is a negative attribute because it produces very long leaf blades that makes for slower and grainy greens.

In The History of Stowe Country Club author Lynn Altadonna, explained that the greens were sodded to velvet bentgrass when the 18 hole course was built in 1962/63. The sod came from a defunct golf course called Kearsarge Golf Club in New Hampshire. The Village Course architect, William Mitchell, was known throughout New England for using and promoting the use of velvet bentgrass. There is no doubt that he had a role in this procurement of sod. The problem with sodding greens, especially velvet, as opposed to seeding greens is the existing thatch layer. Thatch is the layer of old stem material that builds up below the turf surface. Bentgrasses as a whole are prolific thatch producers. While thatch is simply the by-product of producing quality playing surfaces, proper thatch management of is the difference between good and bad turf. The basis of proper thatch management is to mechanically remove the thatch through core aeration and vertical mowing. The USGA recommends the removal of 15-20% of thatch surface annually for quality playing surfaces. This chart explains how to get to those percentages Surface Impact. The strategy at Stowe Country Club is to complete two 1/2 inch core aerations at 1 x 2 inch spacing with an additional Graden verticut. All three methods of cultivation equate to an 18% surface impact. At Stowe Mountain Club a less aggressive management is effective due to the young age of the greens to where the frequency of aerification will impact 10% of the surface.

As stated earlier, velvet bentgrass has fallen out of favor in the golf course industry. The main reason for this is that it is the most prolific thatch producer out of all the cool season grasses. If aggressive aeration and vertical mowing is not done on a regular basis the velvet will become puffy, bumpy, and play poorly. Since velvet at Stowe Country Club was initially installed and was not aggressively cultivated over the years, it has aggressively produced a determinate layer of thatch. Moving forward, proper agronomic practices will be initiated such as aggressive aeration and verticutting to regain the quality of the putting surface. In addition to controlling thatch levels, the cultivation of the greens will assist in conditioning the Penncross to be much smoother and less grainy.

It is our goal at Stowe Golf to produce excellent playing conditions through the production of quality bentgrass. Thank you for your patience during these periodic maintenance procedures to restore the turf. We hope that players will appreciate the  high quality playing surfaces that will grow in based on sound management practices.
