One gallon covers up to 21,300 sq ft
D-Thatch reduces your need to mechanically aerate or dethatch
Great for soil health and root stimulation
Use when it’s hot outside - summer is great

Product Description:
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 on 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.
