Mowing too often can stress your grass, but waiting too long creates a jungle. Discover the golden "one-third rule" of mowing and how to adjust your cutting height based on the season and recent rainfall.
Never remove more than one-third of the grass blade's length in a single mow. Cutting too short removes the plant's ability to photosynthesize effectively, stunting root growth and leaving your lawn vulnerable to weeds and drought. If the grass gets too tall, mow it at a high setting, wait a few days, and mow again at a lower setting.
Frequency: Every 7–10 days.
Height: Raise your mower blade. Taller grass shades the soil, reducing water evaporation and preventing weed seeds from germinating in the harsh sun.
Frequency: Every 3–4 weeks (or as needed).
Height: Growth slows significantly. Mow slightly lower to prevent fungal diseases caused by trapped moisture, but avoid scalping the lawn before a frost.
Frequency: Wait for dry conditions.
Action: Never mow wet grass. It tears rather than cuts, dulls your mower blades, compacts the wet soil, and spreads fungal diseases across your lawn.
