1. Pruning principle
1/3 principle: the amount of trimming should not exceed 1/3 of the total longitudinal height of the stem and leaf tissue, and the rhizome should not be damaged, otherwise the normal growth of turfgrass will be affected due to the imbalance between the growth of aboveground stems and leaves and the growth of underground roots.
2. Trim height
Pruning height (stubble height) is the vertical height of the aboveground branches after pruning. Different turfgrasses tolerate different cutting heights due to their different biological characteristics.
Lawn grasses that grow upright, such as bluegrass and tall fescue, generally do not tolerate low pruning; lawn grasses with stolons, such as creeping bentgrass and bermudagrass, can tolerate low pruning.
The mower should be set on a level, hardened surface when setting the cutting height. Since the lawnmower walks on the stems and leaves of the lawn grass, the actual cutting height of the lawn grass should be slightly higher than the height set by the lawnmower.
The low-cut lawn looks beautiful, but it is not resistant to environmental stress, is often diseased, and is highly dependent on careful cultivation and management. Maintaining a low mowed lawn requires a higher skill level than maintaining a high lawn.
3. Pruning times
The regeneration ability of the lawn is strong, and it can still grow normally after pruning. One is that the old leaves with the upper leaves cut off can still grow normally; the other is that the young leaves that have not been damaged can still grow; the third is that the tiller nodes at the base can produce new branches; the fourth is that the rhizome organs and stubble have the function of storing nutrients , which can guarantee the nutrient requirements for growth.
4. Trim direction
Depending on the direction of mowing, turf stems and leaves are oriented differently, reflecting light differently, resulting in the alternating light and dark bands seen in many stadiums, and fruit collars trimmed by small lawnmowers show the same pattern.
5. Treatment of grass trimming
The grass clippings contain the nutrients needed by plants and are one of the important sources of nitrogen.
Returning this part of nutrients to the soil can reduce the amount of chemical fertilizers and gradually increase soil fertility. If long-term pruning and removal of the cut grass will eventually cause the imbalance of soil nutrients, and it is necessary to apply chemical fertilizers to make up for the nutrients taken away.
