My Fellow Turfgrass Combatants,
Good job. Carry on with your great work in the service of your lawn. In this block of instruction, I will discuss THATCH. That's right; you heard me. THATCH. Thatch buildup results because you are not following orders. So, it is your fault. Thatch can be a good thing - but like many good things; too much is NOT good.
Lawn thatch is the buildup of excessive unwanted material in your lawn that can choke out air, water, nutrients and sunlight.
