Years of aerations and topdressings have caused several collars and approaches to become crowned. The raised crowned approaches and collars on #1, 3, 4, 15 and 16 are interfering with proper surface drainage from the putting surfaces. Interrupted surface drainage can cause significant turf concerns, especially during hot, wet and humid summers (like this past one). Since the crowning slows the surface drainage, more water is pooled and forced to enter the soil at the front of these green. Increased moisture increases soil temperatures, reduces rooting, induces disease concerns, etc. All of which lead to reduced turfgrass health and potential thinning, which we witnessed this season.
To improve the turf health for future summers, the crowned approaches need to be corrected to assure there's positive surface drainage off of the green surfaces. Below is a series of photos illustrating the process on #15.
#15 Crowned Collar and Approach.
Sod is stripped and crowned soil is removed.
The crown is removed to promote proper surface drainage.
Bentgrass sod is returned to collar and approach.
Renovated area is cleaned and rolled.
Finished collar and approach is water and the healing will begin.
