Are you visually monitoring the rootzone under your putting surfaces? Layers or banding make it clear that topdressing is out of sync with aging and growth. The bands of sand seen in the picture are the result of heavy topdressing following aeration. The dark layers in between are made up of organic matter which can restrict the movement of water, oxygen and even roots through the rootzone. Punching (aeration) through the organic layers will reduce their negative impact and must be continued. Future layering can be avoided by increasing the frequency of topdressings between aerations. Physical analysis can aid monitoring, but simply removing small samples as depicted in the image will provide valuable insight to help properlly adjust cultivation programs.
Should questions or concerns arise about topdressing, aeration or any other aspect of your maintenance program call or email anytime. We’re always available.
