Weather for Grass Cutting Cheat Sheet

Last updated: 2023-09-15

For optimal grass cutting, mow when the grass is dry to prevent clumping and ensure a clean finish. Generally, this means mowing after the morning dew has dried, typically around mid-morning or in the afternoon. However, if conditions are particularly wet or the grass is stressed from drought, it's best to postpone mowing.

Summary

• Mow when grass is dry to avoid clumps.
• Best mowing times are mid-morning or afternoon.
• Avoid mowing if the lawn is wet or stressed.
• Use Clime for reliable weather updates.

What is the Best Time of Day to Mow Lawns?

To achieve a well-maintained lawn, timing your mowing based on the weather is crucial. According to university extensions, the ideal time to mow is later in the morning once the dew has lifted, which minimizes moisture content on the grass blades. This ensures a cleaner cut and helps to avoid clumping. Mowing during the afternoon can also be effective, particularly when temperatures are high and the sun has dried the grass thoroughly.

Wet vs. Dry Mowing Guidelines

Mowing wet grass can lead to uneven cuts, clumping, and possible damage to your lawnmower. To maintain lawn health:

• Always check the moisture level of the grass. It’s best to wait until the morning dew has dried or until after a rain.
• Do not mow when the grass is wet, as it can lead to soil compaction and promote fungal diseases.

Influence of Dew on Mowing Timing

Dew can significantly affect your mowing schedule. Typically, dew is worst in the early morning. If it’s particularly heavy, consider waiting until later in the day when the grass is sure to be dry. This will help you avoid potential damage both to your lawn and your equipment.

Mowing Stressed Lawns

Lawn conditions can be impacted by drought or extreme heat. When temperatures exceed 90°F, grass may go dormant and should not be mowed. Cutting during this time not only stresses the grass further but can also lead to inappropriate growth patterns and color changes. Assess the lawn's health before planning your mowing day.

Guidelines for Mowing Height

Mowing height can also play a crucial role in lawn health. Following the one-third rule, you should cut only one-third of the grass blade at any time. If your grass is kept at 3 inches, for instance, you should mow when it reaches about 4.5 inches tall. This approach encourages healthy growth and density.
