Loose soil and rolled soil and rolling are contradictory and uniform. Loose soil is to increase the permeability of the lawn, which is conducive to the absorption of moisture and nutrients from the lawn. Rolling is to increase the turfgrass and promote the growth of turf litter, so that the lawn becomes dense and robust. The combination of the two will not only ensure the healthy growth of the lawn, inhibit the growth of weeds, but also maintain the beauty of the lawn.

Usually two or three times a week watering, especially in arid areas to increase the number of appropriate.
3. The slope of the timely draining bed (generally 2%) should be able to meet the requirements of drainage. If there is accumulated water in some areas, it should be drained manually or drained.

However, if the lawn is seriously deprived of fertilizer, 0.5% urea and 0.5% potassium dihydrogen phosphate solution can be topdressed.

Summertime management of cold season lawns
Most lawns in the northern regions are cold-season varieties, and they have dormant habits in the summer, especially in the early-maturing pods. During this period, the physiological metabolism of the lawn is very slow, and the resistance is also weak. If the conservation management is not strengthened, it will easily cause alopecia areata and even a large area of ​​death, which will seriously affect the landscape effect of the lawn.
