是什么导致茅草过多?
Too much fertilizer, pesticides and irrigation. Aggressive fertilization creates too much plant growth for the microbes to decompose. The excessive use of pesticides kills microbes and earthworms that decompose thatch. Excessive irrigation will drown and kill soil microbes.
割草会产生茅草吗?
Not if the lawn is mowed regularly. Young grass blades are almost all water, and they decompose readily.
The problem is when you mow irregularly. Old, tall grass blades will get fibrous and decompose slowly.
如何防止茅草?
Limit your fertilization to only what is needed. This is subjective, but the more you fertilize, the greater your risk of thatch build-up.
核心通风是很有帮助的. Core aeration stimulates microbial activity in the soil. Core aeration will physically remove thatch, too.
限制杀虫剂的使用. A lawn rarely if ever needs a fungicide or insecticide application.
如果我有太多的茅草怎么办?
Dethatching is recommended if your thatch is 1 inch or thicker.
Dethatching is a destructive process. It should be done when the turf grows actively and can recover quickly. 秋天是个好季节.
You can remove thatch using a vertical mower. These are available at rental dealers, garden centers and hardware stores. Dethatching is also done by lawn care services.
Set the tines at a depth where they rake the thatch but cause minimal damage to the soil.
把碎片耙起来. 这些碎片可以制成堆肥. Irrigate the lawn to activate its healing.
You may aerate, overseed and fertilize the lawn after dethatching. Use a light, half-strength fertilization. Your lawn will recover in a few weeks.
