When To Cut Your Grass

The question of when to mow the grass seems like it should have a straightforward answer. It doesn't. In reality, the answer depends on how fast the grass is growing, what the grass's ideal height is, when you last mowed and what time of day it is. The following information will help you determine the right time to mow your lawn. 

Follow the 1/3 Rule

The 1/3 Rule states that you should never cut more than 1/3 of your grass at a time. Since your lawn will grow at different rates at different times of the year, the length of time that passes between cuttings will depend on the rate at which your grass is growing. During the growing season (late spring and all of summer), your grass will grow more quickly. During the fall and winter, your grass will slow down its growth or grow not at all, depending on your climate, the type of grass and other factors. In the summer, you may mow your lawn as often as more than once per week. During the fall, you may go a couple weeks between cuttings. 

Know the Ideal Height

In addition to the 1/3 rule, you'll need to know what the ideal height is for your type of grass. Warm season grasses like Bermuda should be kept short--around 1 inch tall. Cool season grasses like Kentucky Bluegrass should be kept longer, at around 2 to 3 inches. 

Cutting Often is Best

Many lawn care experts recommend cutting the grass more often rather than less often because short clippings can be left on the lawn, which can in turn contribute to grass fertilization. 

What time of day should I mow the lawn?

Actually, the question should be, when should I not mow the lawn? To prevent lawn stress, avoid mowing your lawn when daytime temperatures are at their peak. You should also avoid mowing your lawn when it's wet, including early morning when the blades are wet with dew. Mowing your lawn when the blades are wet can contribute to the tearing of the blades, which can cause your grass to contract diseases. Wet blades of grass also have a way of clogging the mower. When mowing the lawn, plan to cut grass in the late morning after the dew has evaporated or early evening when the sun is beginning to set.

So the question of when to mow the lawn is very complicated. If you still have questions or would like more information or guidance about when to mow, speak with a professional lawn mowing service or a firm like Williams Lawn Care & Landscaping, Inc.
