How to weed the green lawn!

First, the prevention method in advance.

Before sowing, the land should be deeply ploughed, turned over and buried to remove impurities in the soil and seeds and roots of some weeds, which can reduce the growth probability of weeds.

In addition, sowing time is also very important. Many lawns can be planted in spring, summer and autumn, and spring is a good season for weeds to grow. So if you have the conditions, you can plant a lawn to avoid spring.

Second, fertilization methods.

Nitrogen fertilizer is a kind of fertilizer that many lawns like very much, but many weeds don't like it. So when fertilizing the lawn, you can apply some nitrogen fertilizer. Generally, the ratio of NPK fertilizer is 3:2: 1.

Third, the method of spraying pesticides.

Many lawn growers feel that they can't spray weeding pesticides on their lawns for fear of killing their lawns. However, if you choose the right herbicide, you don't have to worry about this problem. Herbicides are divided into monocotyledonous weeds and dicotyledonous weeds. Before spraying pesticides, we need to determine what kind of lawn we own, and then prescribe the right medicine.

Fourth, artificial weeding method.

This is the most stupid and labor-intensive way, but it is also the most environmentally friendly and thorough way.
