Potassium fertilizer could increase dandelions by 20x

Dandelion (Taraxacum officinale) abundance can be increased by potassium (K) and lime applications. Adding K fertilizer when it is not needed by the grass, or adding lime to increase the pH when the grass does not require such an adjustment, could lead to increased competitiveness of dandelions in that sward.

What is The ATC Doublecut with Micah Woods?

I discuss ATC blog posts, with supplementary information, stories, and the reasons why I thought the topic was worth writing about, and worth reading about. Thus, a doublecut of these topics. This covers grass selection, playability, and all the work done to create a certain type of turfgrass surface.
