To keep your lawn healthy and looking good, it's important to set the right cutting height for your lawn mower blades. Here's a simple guide on how to adjust the cutting height based on different grass lengths..

Ideal Cutting Heights

The 1/3 Rule

Never cut more than one-third of the grass height at a time. This helps keep your lawn healthy by preventing stress on the grass. If the grass is too long, reduce the height gradually over several mowings.

Best Heights for Cool-Season Grasses

  • Fine fescue: 1.5 to 4 inches
  • Kentucky bluegrass: 0.75 to 3.5 inches
  • Perennial ryegrass: 0.75 to 2.5 inches
  • Tall fescue: 1.5 to 4 inches

Best Heights for Warm-Season Grasses

  • Bahia: 2.5 to 4 inches
  • Bermuda: 0.5 to 2.5 inches
  • Buffalo: 1.5 to 4 inches
  • Centipede: 1 to 2.5 inches
  • Kikuyu grass: 1 to 1.5 inches
  • St. Augustine: 1 to 3 inches
  • Zoysia: 0.5 to 3 inches

Seasonal Adjustments

Spring
In the spring, grass grows quickly, especially after rain. For cool-season grasses, set your mower to cut at 3 to 4 inches once the grass reaches about 6 inches tall. For warm-season grasses, mow them to 2 to 2 ½ inches when they reach about 4 inches tall. Cutting the grass slightly shorter at the start of the growing season helps remove winter debris and encourages new growth.
Summer
During the summer, keep the grass a bit taller. For cool-season grasses, maintain a height of 3 to 3 ½ inches. For warm-season grasses, keep them at 2 to 2 ½ inches. Taller grass helps prevent weeds, shades the soil, and retains moisture, which is crucial during hot weather.
Fall
As fall approaches, trim the grass to a medium height. Cool-season grasses can be mowed down to about 2 ½ inches before the first frost, while warm-season grasses should be cut to 1 ½ to 2 inches before cooler weather arrives. Keeping the grass at a moderate length helps protect the roots during winter and reduces the risk of diseases. However, avoid leaving the grass too long, as it can become matted and more susceptible to problems over the winter.

Mowing Frequency and Timing

Mowing Frequency For traditional lawn mowers (not robotic), it's generally recommended to mow once a week. However, the best frequency depends on the grass's growth rate. Follow the 1/3 rule: don't cut more than one-third of the grass height at a time.
Mowing Timing The best time to mow is between 8 AM and 10 AM. This gives the lawn time to dry and heal before evening, reducing the risk of disease. Avoid mowing when the grass is wet, like after rain or watering, because wet grass can cause:
  • Mower clogging and damage.
  • Tearing of the lawn, leaving tracks and compacting the soil.
  • Grass blades not standing upright, making it hard to cut evenly.
Choosing the right mowing frequency and timing helps keep your lawn healthy and looking good.

In summary, adjusting the mowing height is essential for a healthy lawn. Follow the recommended heights for different grass types and seasons, use the 1/3 rule, and mow at the right frequency and time. Utilizing the Auto Plan Settings can help maintain optimal lawn care effortlessly.
