Mow now — every 7 days
Target height: 2.5" (63mm)
Mow every 7 days at 63mm.
Mowing in Peoria spans two different strategies. Zone 6a sits in the transition zone — warm-season grasses thrive in summer while cool-season grasses handle winter. Getting the mowing height right for each grass and each season is the key to a healthy Peoria lawn year-round. Most Peoria homeowners mow too short in summer and too infrequently in spring — both costly mistakes this guide corrects.

Seasonal Mowing Guide for Peoria

Summer: Raise height, protect roots
Frequency: Every 10–14 days as growth slows
Height: 75–100mm
Taller grass means deeper roots and less evaporation. This is the most important seasonal adjustment.

Mowing Tips for Peoria, Zone 6a
The transition zone (zones 6–7) requires adjusting mowing height dramatically between seasons. Summer height should be 25–40mm higher than spring.
If you have Tall Fescue, maintain at 90mm through summer. This is higher than most guides suggest but critical for heat tolerance.
Never scalp warm-season grasses in fall transition. Leave at least 50mm to protect crowns entering dormancy.
Leave clippings unless clumping — they decompose rapidly and return nutrients.
Mow when grass is dry whenever possible — wet grass clumps and leaves uneven cuts.
Frequently Asked Questions
When should I start mowing my lawn in Peoria?
In Peoria’s zone 6a climate, begin mowing when grass shows active growth — typically March–April. Start when soil consistently exceeds 10°C at 5cm depth. Set mower at maximum height for the first 2–3 cuts.
What height should I mow my lawn in Peoria?
For Peoria’s dominant grass in zone 6a: Kentucky Bluegrass at 2.5" (63mm) year-round, raised to 3.5" in summer. Never cut below 1.5". Taller is almost always safer than shorter.
How often should I mow my Peoria lawn in summer?
In Peoria’s zone 6a, Kentucky Bluegrass needs mowing every 7–14 days in peak summer. If growth slows in August heat, extend the interval. Never skip so long that you remove more than one-third of the blade.
When should I stop mowing my lawn in Peoria?
Cool-season grasses in Peoria can be mowed until the ground freezes. Final mow at 65mm.
Should I bag or mulch grass clippings in Peoria?
Mulch (leave) clippings whenever possible. They return up to 25% of the nitrogen your lawn needs — reducing fertilizer requirements. Only bag when clippings are too long and clumping, the lawn has a fungal disease, or you’ve skipped mowing and removed more than one-third of the blade.
