If you’ve lived in Georgia for more than one summer, you know the drill: temperatures climb into the 90s, rain disappears for weeks at a time, and the lush green lawn you worked hard for all spring starts to turn brown and brittle almost overnight.
The good news? A brown summer lawn isn’t inevitable. With the right strategy — timed to Georgia’s unique climate — you can keep your grass healthy, green, and resilient all season long. Here’s what the professionals at Great Estates Landscaping recommend.
Understanding Georgia’s Summer Climate
Georgia summers are no joke. From June through September, the state experiences a combination of high heat, extended drought, intense humidity, and powerful UV exposure. Average highs across Newton County regularly reach the upper 80s to mid-90s°F, and meaningful rainfall can disappear entirely for weeks in July and August.
This combination of heat and drought puts grass into survival mode. Understanding what you’re up against helps you stop fighting nature — and start working with it.
1. Choose the Right Grass for Georgia
This is the foundation of a summer-proof lawn. Georgia falls in what’s known as the “transition zone” — warm-season grasses thrive here in summer. Here are the best options:
- Bermudagrass – The most heat- and drought-tolerant option. Goes dormant in a controlled way and bounces back fast. Ideal for full-sun lawns in Covington and Madison.
- Zoysiagrass – Slower-growing but dense and resilient. Handles heat and moderate foot traffic well.
- Centipedegrass – A low-maintenance option that does well in Georgia’s acidic soils.
If you currently have tall fescue, expect it to struggle significantly during peak summer. Fescue often requires overseeding each fall to maintain density in Georgia.
2. Water Deeply, But Less Often
Watering too frequently but not deeply enough is one of the most common mistakes Georgia homeowners make. Light daily watering trains grass roots to stay shallow — making your lawn more vulnerable to drought, not less.
The right approach: water 2–3 times per week, applying 1 to 1.5 inches per session. Always water in the early morning (4–8 a.m.) to reduce evaporation and prevent fungal disease. Avoid evening watering — wet grass overnight is a recipe for problems.
During extended dry spells, allow warm-season grasses to go into temporary dormancy rather than overwatering. They’re remarkably resilient and will bounce back when rain returns.
3. Mow at the Right Height
Cutting too short exposes soil to direct sun and stresses roots. Longer blades shade the soil and reduce moisture loss. Never remove more than one-third of the grass blade in a single mow. Recommended summer mowing heights by grass type:
| Grass Type | Summer Mowing Height |
| Bermudagrass | 1 – 1.5 inches |
| Zoysiagrass | 1.5 – 2.5 inches |
| Centipedegrass | 1.5 – 2 inches |
| Tall Fescue | 3.5 – 4 inches |
Also keep mower blades sharp. Dull blades tear grass rather than cutting cleanly, leaving jagged edges that brown and invite disease.
4. Fertilize Strategically
Fertilizer applied at the wrong time or in the wrong amount can burn drought-stressed grass. For warm-season grasses, a balanced fertilizer in late spring (May) builds strength heading into summer. A light feeding in June or early July can maintain color, but avoid heavy nitrogen applications during peak heat.
For cool-season grasses like fescue, skip fertilizing in summer entirely and plan for a fall feeding in September–October instead. Soil testing every 2–3 years is the most accurate way to know exactly what your lawn needs.
5. Aerate to Beat Compaction
Georgia clay soil compacts under summer foot traffic and heat, preventing water and nutrients from reaching grassroots. Aeration — pulling small plugs of soil from the lawn — opens things up dramatically.
- Warm-season grasses: aerate in late spring to early summer (May–June)
- Cool-season grasses: aerate in early fall (September–October) — never in summer
A properly aerated lawn absorbs water more efficiently, meaning less runoff, fewer dry patches, and a root system that handles summer heat far better.
