N-Ext D-Thatch™ focuses on composting thatch faster by encouraging microbial activity at the soil surface and increasing heat. This exothermic release by increased soil activity will break down thatch from the soil level up.
D-Thatch is a maintenance product. This means that with regular applications yearly in summer you can keep thatch buildup in the lawn to a minimum. It can also be used to help speed up the recovery of dead spots in the lawn from disease or insects. The secret to N-Ext D-Thatch™ is molasses. The sugars bring the microbes up to munch and when the molasses runs out, they turn to the thatch as a secondary food source.
What is Thatch?
Thatch is the layer of dead organic materials lying between your healthy turfgrass and soil/root system. It usually consists of stems, stolons, rhizomes, and roots that haven’t decomposed. When your thatch layer is manageable at around 1/2" thick or less, it is a nice place for microbes to hang out which also helps this area to retain moisture. This also helps keep the soil cooler on the hottest of days.
Is D-Thatch As Good as Mechanical D-Thatching?
No, it's not. Using those machines to literally rip out thatch is much more aggressive and immediate than using D-Thatch. D-Thatch is more of a maintenance-type product. If your thatch is ok or just getting out of hand, you can apply D-Thatch 3-4 times during the summer and it will, over time, melt the thatch down.
