The Science of Proper Mowing: Frequency and Height

Mowing is the most common lawn maintenance task, but it’s often done incorrectly. Many homeowners treat mowing as a chore to be completed on a fixed day every week. However, professional turf management dictates that mowing should be based on growth rate, not the calendar.

Why the "One-Third Rule" is Non-Negotiable

The golden rule of mowing is to never remove more than one-third of the leaf tissue in a single cutting. Cutting too much at once causes significant stress to the plant, reduces its ability to photosynthesize, and forces the grass to use stored energy to recover rather than growing deeper roots.

• Scalping: If you cut into the crown of the plant, you expose the delicate stems to the sun, leading to browning and potential death.
• Weed Control: Taller grass shades the soil, preventing weed seeds (like crabgrass) from germinating.

Adjusting Height by Season

As temperatures rise in the summer, most lawns benefit from being kept 0.5 to 1 inch taller than their spring height. This extra shade helps the soil retain moisture and protects the root system from heat stress. In our calculator, we automatically factor in these seasonal growth curves to help you maintain the perfect balance.
