Summer Lawn Care: Water, Mow, Fertilize for a Heat-Proof Lawn

Hot, dry summers stress lawns. A proactive routine—deep watering, smart mowing, slow-release feeding—keeps grass green, resilient, and barefoot-ready all season.

Know Your Grass

• Cool-season (fescue, bluegrass, rye): Peaks spring/fall. Summer = survival mode.
• Warm-season (Bermuda, zoysia, St. Augustine): Thrives in heat. Grows aggressively summer.

Adjust expectations and care to type.

The Big Three

1. Mow High & Often

• Never remove >1/3 blade height.
• Cool-season: 3–4″. Warm-season: 1.5–2.5″.
• Mulch clippings (returns N, moisture). Only bag if wet/clumping.

2. Water Deep, Not Daily

• 1–1.5″ per week, in 1–2 sessions. Early morning (4–8 AM).
• Probe: screwdriver should slide 6″ easily.
• Dormant cool-season lawns: ½″ every 2–3 weeks to keep crowns alive.

3. Fertilize Slow & Steady

• Polymer-coated slow-release (e.g., 20-0-10). Feeds 8–12 weeks.
• Spring: High N for green-up.
• Fall: High K for root storage/winter hardiness.
• Summer: Skip high N on cool-season; light feed OK for warm-season.

Protect the Turf

• Move furniture/kiddie pools daily—heat + weight = dead patches in hours.
• Sharpen mower blades monthly.
• Scout for grubs, chinch bugs, fungal spots—treat early.
