Why Cover Greens?

16 and 2 greens have now been covered for close to 2 weeks.  These two greens were covered because of all the new sod laid during restoration and expansions last fall.   The covers were put on to help the sod root better with the slow start to spring this year.  

Covers insulate and keep heat underneath just like using a blanket.  This helps to keep the soil and plant warmer during cold nights.  

The covers are helping.  After checking under them Monday afternoon the turf is starting to wake up and grow out of some winter damage.  Surface and Soil temperatures are also higher than greens without covers

Winter damage to the surface of  9 green

The decision was made Tuesday afternoon to cover greens 5, 9, and 10.  These three greens have the largest amount of winter damage.  The covers will help the soil temps warm up quicker over the next week, and hopefully we see new growth coming through in damaged areas. 

With the slow start to spring this year, there needs to be some growth before we put traffic and added stress on playing surfaces.  Each green will be handled different this spring.  Hopefully the weather cooperates and there are some warmer night time temps soon!

Spring Golf Update

Since the last update on spring golf, Rockville Links recieved 4" of snow on Friday, the first day of Spring.  Temps reached the 60's on Saturday then quickly dropped back below freezing at night.  These drastic swings in weather have ugly'd up more turf throughout the course.  Most still seems to be superficial damage, but the full extent of damage will not be know until the turf actually begins to grow.  

#9 green did not have the visual damage last week prior to the crazy weather swings

Hopefully with the warm weather and rain Rockville is receiving today will help to wake things up.  Friday and Saturday again have a high of 38 and a chance of snow.  After Saturday the long term looks Good! 50's during the day and 30's at night.  This means there will probably be some heavy frosts each morning, but hopefully it will stay above freezing so the grass will start to grow. 

 Active growing grass can take traffic and recover.  This is what we look for before opening greens and allowing carts.  

Hopefully Mother Nature will cooperate this next week and we can begin the 2015 Golf Season.

We still have to be careful when to allow traffic on grass.  The picture above is damage caused by someone walking their dog down 1,2, and 3 on a late afternoon in December last year.  This is the reason behind frost delays.  Also when temps drop below freezing it also can freeze the grass blade making it susceptible to damage.

The blog will be updated every time there is a change.  So keep checking back.

Getting ready for Spring to Arrive

2 Green March 17th
Low area in the middle of green severely stressed after this harsh winter.
Desprite being stressed this turf should grow out once weather allows for growth

Finally, it is starting to look like spring at Rockville Links.  Snow and ice only remain in a few pockets throughout the course allowing us to finally get out see The Links.  Although, there are many patches that look beaten up from the harsh winter, I have not seen any areas where we suffered any WinterKill.  Deciding to clear greens to accelerate the ice melt really helped relieve stress from many struggling areas.  (This Process is further details in the previous March 9 blog post)

So what does this mean for the membership of Rockville Links?

The Links needs to continue to dry out and firm up.  Besides walking the crew is not able to get off the main roads and paths.  Hopefully later in the week we are able to venture off road. There is plenty to clean throughout the course, especially from all the geese activity the last 10 days.  

Once we do dry out we still have to keep traffic off areas that were severely stressed this winter.  I would like to see growth and recovery before we add any more stress.  

This same idea applies to greens.  Our greens will be the first turf ready for play this spring.  This is because of internal drainage, better sandier soils, and fewer shade issues than other playing surfaces.  Our greens are also predominately Poa Annua, which is a grass that comes out of dormancy quicker and is better suited for spring conditions than other grasses. 

The 7-Day forecast has every night dropping below freezing and a chance of snow Friday.  Coming into this week I would say we are 10 days behind last season, which had first round of golf played in late March.  Once we get through this next wave of cold weather, we should have a better idea how the season is shaping up.    

The course has come a long way in one week.  Hopefully we dry out, and the weather catches up to spring in the next week!

Spring?

Overhead view Friday March 6th

This Winter has been very unique.  The first 2 weeks of November was amazing weather, followed by some record lows to finish out the month.  December was beautiful and there was golf played right through New Years Eve.  January was pretty normal, but did begin forming ice layers on playing surfaces.  The end of January also brought a very impressive storm that left 18" on Rockville Links. This snow helped to insulate the original ice layer that formed.  February was the coldest ever recorded in  NYC and Long Island. 

All this weather set up the crazy first week of March.  Two separate rain storms followed immediately by snow and freezing temps in the same week.    

Huge puddle formed on #10 Green on Wednesday March, 4 during the heavy rain storm.  This was followed by 8" snow and temps dropping to 12 degrees.

All this weather formed 3-5" of ice on playing surfaces.  Some greens have been under ice cover for 35-40 days.  So the decision was made Friday March 6 to clear snow off greens to expose the ice.  

Two potential issues led to this decision.  First, ice cover for an extended period of time traps bad gases in the soil that can led to turf loss.  Second, the long term forecast called for a freeze thaw pattern all week, and saturated turf the freezes quickly causes crown hydration.  

Luckily the weather turned out better than predicted this weekend, and now is not going to drop below freezing till late in the week.   The thick ice layers have begun to melt, and we are doing everything we can to help water move from the surface.  In the next few days some frost should lift from the the ground and the Internal Drainage installed in the greens the last few years will really help out!

Using a snow blower to expose thick ice layer on #7 Green

Most greens had 3" of ice with 14-18" of snow on top of the ice

Some greens had 4"+ of ice and close to 3' of snow in spots.  So we had to use larger equipment to clear these greens.

Applied pigments and dark colored amendments to help melt ice. 

Restoration

The last few months at Rockville Links have been a blur.  Many changes have taken place and I am well overdue on a post.

The major project that began in November was working with Jim Urbina to restore holes 2, 3, and 16 to the original 1924 Devereux Emmet design.  The Restoration was done by our crew "in house" along with Jim Urbina and his shapers.  We utilized old overhead photos of Rockville Links to guide us in our Restoration.  

As we rounded out 2014 here at The Links, we really set up 2015 for a New Old Look for the membership.  Hope you all have a Happy New Year, and I will post more from the work so you can see what 2015 will look like at Rockville Links. 

#2 Green during construction

#2 Left Side Fairway Bunker.  Fairway runs right into the bunker now.
All fairway sod was cut and moved to restore original fairway lines. We also wanted sod to match so it blends in seamlessly.

#16 Left Side had 8 trees transplanted to restore the tree lined corner

New #3 Right Side Fairway Bunker

Great care was taken to recreate the sod walkpaths from the original Emmet design.

Aeration: A Necessary Evil

The DryJect process pictured above was completed Wednesday afternoon.  This process blasts water into greens and creates a suction that fills the holes with sand.  Workers must continuously load dry sand into the machine much like the drill-n-fill process we perform in November. 

 The week prior to Dryject we pulled a 1/2" core 5-6" deep into the soil profile followed by a deep verti-cut.  Then seed, sand and soil amendments were applied to the greens.  

So why do we aerate?  

Aeration helps remove thatch, organic matter, and heavy soils that are not desirable to playing surfaces.  It also allows for proper air exchange in the soil.  All this adds up to healthier roots and grass.  This all leads to better more consistent playing conditions.  

There are different goals for each area on the course.  Tee and fairways is to remove as much thatch as possible.  Approaches to remove thatch and incorporate sand for firmness.  Greens are to remove some thatch and organic matter, but need more work at 4 inches and greater in the soil profile.  This will help utilize the new drainage, create healthier deeper roots, and help return playing conditions faster after rain events.  

Thanks for your patience over the last few weeks!

Using Technology

Moisture Meters

This is our most used piece of technology at The Links.  It measures the % of water content in the soil. This number helps us quantify a number to shoot for when water each morning and also afternoon.  So it helps to find a drier area before it shows signs of stress, and helps improve play-ability by keeping greens consistent throughout the course.

TruFirm

This is the newest addition to our tools.  This firmness meter just became available this spring.  We are still trying to integrate it into our normal practices and find a balance between moisture and level of firmness that provides ideal conditions for the club.  It has also been used to test for differences in bunker play-ability throughout the course

DJI Phantom

I personally purchased the DJI Phanom a month ago.  Besides being something that is fun to operate is has also shown be be a very useful tool here on the golf course.  When used with my GoPro camera it has taken some great overhead photos and videos.  

Through social media it has also been very interesting to see how other superintendents and occupations are using this as a tool.  

GoPro Camera

The GoPro has been the most useful to help document what is being done on the course.  From pictures, videos, and time lapse many photographs posted here, twitter, and the clubs newsletter are taken with this camera.  The small versatile came is also used with the DJI Phantom for overhead photography.
