茅草是什么??

Thatch is a layer of roots, shoots and stems, both living and dead. This brown mat develops between the green vegetation and the topsoil.

茅草是如何发展的?

你的草坪是一个有生命的系统. It produces organic matter (grass blades, stems and crowns) at the same time it decomposes organic matter. When your lawn produces more organic matter than what it can decompose, thatch starts to build up.

我应该有多少茅草?

薄一层就好. It insulates the lawn from temperature and moisture extremes. A little thatch makes the lawn more resilient.

厚厚的一层是不好的. When thatch gets to be 1 inch thick, it makes roots more susceptible to drought, diseases and rot.

我如何测量茅草?

从你的地盘上割一块楔子. Pretend you are cutting a piece of pie and go down, 2 inches into the soil. 拔出楔子. 测量垫子的厚度.

部分

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.
