Power raking is the act of physically removing the thatch from a lawn.
Thatch is composed of a tightly intermingled layer of stems, leaves and grass roots, which accumulates between the vegetation and the soil. Too much thatch increases the turf’s susceptibility to diseases, reduces its tolerance to drought, cold, and heat; and hinders the movement of air, water, fertilizers, and nutrients into the soil. In severe cases roots of the grass will not grow into the soil but actually take root in the thatch layer making the turf susceptible to drought and heat stress.
You can check and see if your lawn requires dethatching by combing through the grass until you can see the dirt. If you can see more than 3/4 of an inch of thatch (dead brown spongy grass) between the soil and the blade of the grass you may need to power rake.
The best way to quickly repair a thatch problem is by power raking the lawn or physically removing the thatch layer. To prevent major damage power raking must be performed before the lawn greens up. When a severe thatch layer is discovered after the lawn has already greened-up than the thatch should be controlled through an increase of microbial activity and/or a reduction of the growth rate of the turf.
Thatch Preventative Practices
- Mowing – Never cut more than 1/3 of the blade of grass at one time. Mulching does not increase the tendency to build thatch. Change the mowing height to 2.5 inches in the spring and fall and increase the height to 3 inches in the summer.
- Fertilizing – Fast release nitrogen applications will result in a decrease in thatch decomposition and an increase in thatch production rates.
- Irrigation – Avoid light and frequent watering. Always irrigate the turf deeply and infrequently. This entices the roots of the grass to grow deep into the soil instead of the thatch layer.
- Pesticide – Pesticides negatively affect desirable microorganism and earthworm populations. Pesticides should be avoided unless absolutely necessary.
