Lawn mowing isn’t just about appearances — it’s one of the most important steps in maintaining a healthy, dense lawn. Done properly, it promotes lateral growth, reduces weeds, and builds resilience.

Follow These Best Mowing Practices:

Mow regularly: Frequent mowing helps avoid removing too much of the leaf blade at once, reducing stress. It also encourages denser growth, which naturally suppresses weeds.
Follow the 1/3 rule: Never remove more than one-third of the grass blade in a single mowing. Cutting too much weakens the plant and its roots.
Set the right mowing height: These heights reduce weed growth, minimize water loss, promote deeper root systems and help the lawn withstand stress from heat and drought.
- Spring & Fall: 3–4 inches
- Summer: 4–5 inches
Avoid mowing in extreme heat: Don’t mow when temperatures exceed 85°F — this can lead to rapid water loss and heat shock.
Mulch your clippings: Leave clippings on the lawn to return nutrients to the soil and support healthy soil biology.
Change directions: Vary your mowing pattern each time to reduce soil compaction and promote upright growth.
Keep mower blades sharp: Sharp blades make clean cuts, reducing water loss and the chance of disease.
