How to Prepare Your Lawn for Summer in Georgia

Summer readiness starts in late spring. A few key steps in April and May make the difference between a lawn that survives and one that thrives.

How-To GuidesApril 30, 2025

Step 1: Get Your Fertilization on Track

By late April, your warm-season grass should be fully green and actively growing. If you have not applied spring fertilizer yet, now is the time. A slow-release nitrogen fertilizer gives bermuda the sustained feeding it needs heading into the growing season. For centipede, keep nitrogen light and consider an iron supplement for color. The goal is building a strong, dense turf that handles summer stress.

Step 2: Address Remaining Weeds

Pre-emergent should already be down, but post-emergent treatments target any breakthrough weeds. Nutsedge becomes a problem starting in May — it requires specific herbicides (standard broadleaf products do not work on it). Get existing weeds under control before summer heat limits your treatment options. Some herbicides can stress warm-season grass when applied in high temperatures.

  • Treat nutsedge with a sulfonylurea herbicide, not standard broadleaf products.
  • Apply post-emergent herbicides in the morning when temps are below 85 degrees.
  • Target remaining winter weeds before they go to seed.

Step 3: Check Your Irrigation System

Before you need your irrigation system, make sure it works. Run each zone and check for clogged heads, misaligned sprinklers, and dry spots. Replace broken heads. Adjust coverage so water hits the lawn, not the sidewalk or house. A properly functioning irrigation system is your primary defense against summer drought stress.

Step 4: Raise the Mowing Height

As temperatures climb, raise your mowing height by half an inch. Taller grass shades the soil, reduces water evaporation, and keeps root temperatures lower. Sharpen your mower blades — dull cuts cause browning at the tips and stress the plant. Plan to mow at least weekly during peak growth (May through August for bermuda).
