How to Trim Tall Grasses

Grass grows tall if the maintenance is irregular. Mowers can break from the process of cutting such lengths, since they are designed to cut at a maximum height of 4 inches. Fortunately, there are other tools that you can use to begin the process of cutting the grass that will not malfunction from the additional height. After the initial trimming, the process of cutting tall grass is similar to the process required for shorter lengths.

Instructions

    • 1

      Cut the grass with a hedge trimmer or scythe to a height of about 5 inches. Remove the long clippings to prevent them from blocking out sunlight and creating a favorable environment for disease. Leave the grass to recover for a week.

    • 2

      Set the blades on the lawn mower to the highest level and mow the grass. Leave the short clippings on the lawn to contribute nutrients. Let the grass rest for another week.

    • 3

      Lower the blades on the mower slightly and mow the lawn again. Let it rest for another week.

    • 4

      Repeat Step 3 until the lawn is as high as you want it. A height of 1 to 2 inches is ideal for warm-season grasses. Keep cool-season grasses longer to reduce stress in the summer.
