Alabama Lawn Mowing Calendar
Published: February 1, 2026 · Updated: April 23, 2026
Alabama's humid subtropical climate and long growing season create a warm-season grass environment that demands year-round attention. Bermuda and Centipede dominate most residential lawns, with Zoysia increasingly popular in Birmingham and the northern third of the state where winters are slightly cooler.

Mowing Tips for Alabama
Never mow during peak afternoon heat (12–4pm) in summer. Morning mowing reduces heat stress on cut grass.
Raise mowing height by 15–25mm during heat waves. Taller grass shades roots and reduces soil moisture loss by up to 25%.
Never remove more than one-third of the blade in a single mow. Removing too much causes shock, browning, and weed invasion.
What Makes Mowing in Alabama Different
Mowing in Alabama is a near-year-round activity with only a brief winter slowdown rather than true dormancy. Bermuda Grass lawns require consistent weekly mowing at 25-50mm from April through October, with scalping in early April to remove winter debris and stimulate spring green-up. Centipede, the second most common choice, requires completely different management — mow at 50-65mm, fertilize sparingly, and resist the temptation to intensively manage a grass specifically adapted to low inputs. Alabama's heat and humidity from June through September create intense fungal disease pressure; Large Patch on warm-season grasses and the relatively rare but devastating Take-All Root Rot both thrive in the combination of high temperatures, abundant moisture, and closely mown turf. Morning mowing and prompt clipping collection during active disease periods reduce spore spread significantly. Mobile and Gulf Coast communities face additional challenges from salt spray during tropical weather events and chronic chinch bug pressure in St. Augustine lawns — a pest whose drought-stress-like damage is often misdiagnosed. The state's red clay soils, iconic across central and southern Alabama, compact severely and drain poorly when wet; timing mowing around the state's frequent summer thunderstorms matters more here than in most places, and annual core aeration in late August is practical for maintaining consistent mowing conditions.

Frequently Asked Questions
When should I start mowing my lawn in Alabama?
Start mowing in Alabama when grass shows active green growth and soil temperature exceeds 10°C. For zone 8a, this is typically February–March. Set mower at maximum height for the first 2–3 cuts.
What height should I mow St. Augustine Grass in Alabama?
St. Augustine Grass in Alabama should be maintained at 75mm during spring and fall, raised to 90mm in summer. Never cut below 50mm.
How often should I mow my lawn in Alabama in summer?
In Alabama's zone 8a climate, St. Augustine Grass typically needs mowing every 7–14 days in peak summer. If growth slows in heat, extend the interval.
When should I stop mowing my Alabama lawn in fall?
Warm-season grasses in Alabama go dormant when temperatures drop below 10°C — typically November. Final mow at 75mm.
Should I raise my mowing height in Alabama summers?
Yes — raising mowing height by 15–25mm in summer is one of the most important adjustments for Alabama lawns. Taller grass shades roots, retains soil moisture, and reduces heat stress. This applies to all grass types.
