Danger for your FLL or USGA type greens?
Many greens are getting up in age, which mean the growing medium known as “the rootzone” is getting old too. A serious problem, yet little known, is the loss of capillary action. Capillary action is a pulling behavior of liquids through narrows spaces which can defy gravity (think of a paper towel sucking up water). This action is vital to drainage and a healthy rootzone.
