Generally, what portion of the leaf blade should be removed from turfgrasses in one cutting?

When maintaining turfgrasses, it is recommended to remove about one-third of the leaf blade in one cutting. This guideline helps promote overall lawn health and growth. Removing this amount allows the grass plants to continue photosynthesis effectively, which is crucial for their recovery and vigor. By leaving enough leaf surface, the turf can maintain its ability to produce energy while still being cut back to a manageable height.

Removing too little can lead to a buildup of thatch and potential pest problems, while cutting more than one-third can stress the plants, making them more vulnerable to diseases and reducing their growth capacity. This balance is essential for maintaining a healthy lawn, particularly in the climate and growing conditions of Louisiana, where heat and moisture play significant roles in grass health. The one-third rule is supported by many horticultural practices as an effective strategy to encourage lush, resilient turf.
