Greens & Fairways Recovery Process


Snow & ice from the winter of 2014
 
With the numerous blog posts over the past several weeks I would hope that everyone is informed about the issues we are dealing with after the harsh winter.  Both greens & fairways were affected the most due to the fact that water was unable to drain off the surface and froze creating the ice that ultimately led to the damaged turf.  As the weather SLOWLY turns for the better, the focus is on recovery.  This post is to provide a little more detail into the steps we are going to take & estimated time frame for the recovery process on the greens.  I will categorize the recovery process in stages with four stages and then give a brief description of each stage.

Stage 1:  Aerification, seeding, & topdressing

This process includes the standard aerification with core removal and cleanup followed by drop spreading a blend of 3 varieties of bentgrass & topdressing the greens with sand.  This is a pretty simple and effective step that is a standard practice.  It allows us to remove organic matter and incorporate topdressing sand which aids in numerous benefits such as reduced compaction, eliminate any thatch accumulation, etc.  The seed is dropped into the aerification holes for good soil to seed contact which is essential to seed germination.  We try to fill in the aerification holes as best we can to provide as smooth of surface as possible as the turf heals in normal years but this year we will be looking to establish new turf due to the damage from the ice.  This process was completed!!

Stage 2:  Slit Seeding & topdressing

This process is very unique but essential to greens due to the circumstances.  The slit seeder will cut parallel lines through the turf as it drops seed into the slits.  This provides great seed to soil contact closer to the surface than aerification thus making it more efficient in turf reestablishment.  We will run the slit seeder in multiple directions on the damaged areas incorporating as much of the bentgrass seed blend as possible at a rate of 2-3 lbs per 1000 sq ft.  Once the slit seeder is complete we will sand topdress once again to fill the voids created by the machinery.  Stage will be completed today!!

Stage 3:  Covering the damaged greens

This step will be the most restrictive part of the process because it will cause the closure of these greens but is also the most important in the recovery process.  The cover will allow the soil temperatures to increase at a quicker rate by serving as a blanket.  Soil temperatures currently are in the low 40's and we need soil temperatures at roughly 55 degrees in order to get good seed germination.  I will be covering 12 greens or portions of greens with the focus on the more severely damaged greens and/or areas of greens.  This will be completed today and leave these greens closed so please use the temporary greens.

Stage4:  Recovery Time

This is the million dollar question and there is no set time frame.  Improved weather would go a long way in decreasing the closure time but until Mother Nature decides that, we will keep the greens covered and closed.  This is the best possible decision in order to prevent this situation from affecting the prime summer months of the golf season.  We are taking an aggressive and positive approach to the situation and  I believe that some of the greens will be able to be opened much sooner than others depending on the overall damage of each green.  Less damage will require less time and so forth.  I will update the blog weekly with the recovery progress and possible changes to the status of the greens.

Time will heal all wounds and we will be back to normal conditions.

Fairway Damage & Recovery

The fairways also have damage from the winter and these damaged areas will have to go through a recovery process also.  Fairways are not as significant due to the fact that putting is not part of its function.  Be that as it may, we will take the necessary steps of aerification & seeding the more severely damaged areas once we have determined the areas.  Please follow cart restrictions in order to aid in the recovery process.

The situation we are faced with is somewhat unprecedented for our area but we are forced to deal with it properly in order to return the course to its original beauty.  We are not the only course dealing with this issue as the harsh winter caused havoc to numerous courses.  I ask that you please be patient while we take the necessary steps in the recovery process and thank you in advance.
