Why Your Grass Turns Yellow in Patches

Follow the One-Third Rule

Never cut more than one-third of the grass blade's height in a single mow. Cutting deeper than that shocks the lawn, weakens the roots, and leaves it vulnerable to disease and drought stress.

Mowing Frequency by Season

• Early spring: every 7–10 days as growth ramps up

• Peak summer: every 5–7 days for fast-growing grass types

• Late summer/fall: every 10–14 days as growth slows

• Winter (warm climates): as needed, often once a month or less

Grass Type Changes the Math

Cool-season grasses like fescue and Kentucky bluegrass grow fastest in spring and fall, while warm-season grasses like Bermuda and Zoysia peak in summer heat. Your ideal schedule shifts depending on which type is in your yard.

Service Stats

Signs You're Mowing Too Often

• The grass is too tall, cuts are uneven, and clippings are scattered.

• Just right: consistent color, even height, minimal clippings left behind

• Too often: thin patches, exposed soil, stressed-looking grass

When to Break the Schedule

Heavy rain, drought, or extreme heat are reasons to skip or delay a mow — not stick to a fixed calendar date. Mowing wet or heat-stressed grass does more harm than waiting a few extra days.
