What problems should be paid attention to in lawn mowing?

Master the appropriate pruning height. Cutting the lawn too low will have a bad effect on the lawn Cutting the lawn too high will give people a feeling of untidiness. At the same time, the seedlings will wither, the top will bend and the leaves will be rough, which will greatly reduce the density of the lawn. The general cutting heights are: creeping bentgrass 2-2.5 ㎝, Bermuda grass 2.5-3 ㎝, weeds 3-4 ㎝, Kentucky bluegrass 4-6 ㎝ and tall fescue 5-7 ㎝. A pruning amount should not be too heavy. In practice, we can master the one-third principle, that is, the mowing part should be within one-third of the height of the lawn. If the lawn is too high, don't trim it to the required standard height at one time. The correct way is to do it several times more and gradually reach the required height. In summer, in order to improve the tolerance of lawn to high temperature and drought, the stubble of cold lawn should be higher. When the weather gets cold, the stubble height should be appropriately increased in the early and late growth stages of warm soil lawn. If the damage is caused by pests and human factors, the stubble height should be increased.

Trim the lawn when it is dry. Avoid pruning when it is hot at noon. Do not water immediately after cutting (1 hour later) and do not exercise. The blade of lawn mower should be sharp and the blade incision should be neat. Otherwise, it will not only affect the appearance, but also easily lead to diseases. Do not spray pesticides or fertilizers immediately after cutting. Before mowing the lawn, remove the sundries, especially hard objects, so as not to damage the blade. Excessive pruning is strictly prohibited in early spring, dormant in midsummer, and generally not cut one month before yellowing in late autumn. Lawn can't be mowed after infectious diseases appear. Water in time 1-2 hours after cutting. It can't be cut without water supply in a dry and hot climate. The same lawn should not be trimmed repeatedly at the same time, at the same point and in the same direction, so as not to tend to grow in the same direction and appear texture phenomenon. After mowing the grass every time, pay attention to cleaning the machinery to prevent rust and pests. Blades should be polished and maintained frequently. When trimming, pay attention to the fact that the blade of the trimmer cannot collide with hard objects, so as to avoid accidents or damage to the blade when the machine suddenly jumps up. Remove the cut grass leaves in time, especially the grass leaves that are not easy to fall off the ground and attach to the lawn after drying, otherwise it will not only affect the appearance but also breed germs.
