Mow now — every 7 days

Mow every 7 days at 63mm.
Mowing in Roanoke spans two different strategies. Zone 6b 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 Roanoke lawn year-round. Most Roanoke homeowners mow too short in summer and too infrequently in spring — both costly mistakes this guide corrects.

Seasonal Mowing Guide for Roanoke

Summer: Raise height, protect roots
Frequency: Every 10–14 days as growth slows

Mowing Tips for Roanoke, Zone 6b
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 Roanoke?

For Roanoke’s dominant grass in zone 6b: 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 Roanoke lawn in summer?

Should I bag or mulch grass clippings in Roanoke?
