After a long, hot summer, many lawns show signs of stress—thin patches, brown spots, and weeds that seem to pop up overnight. September is the perfect time to revive your turf and set the stage for a lush, healthy lawn that thrives through fall and returns strong next spring. With the right recovery strategies, you can repair summer damage and enjoy a greener, more resilient yard.

Heavy foot traffic, summer heat, and drought can all lead to compacted soil. Compaction makes it difficult for water, air, and nutrients to reach grass roots. Core aeration—removing small plugs of soil from the lawn—opens up the ground, allowing roots to breathe and absorb what they need to recover. You can rent an aerator or hire a professional for best results.

Overseeding is the process of spreading grass seed over existing turf to fill in thin spots and improve density. September’s cooler temperatures and increased moisture make it ideal for seed germination. Choose a grass variety suited to your region and lawn type for the best results. After aerating, overseed immediately, then lightly rake and water well to ensure good seed-to-soil contact.

A slow-release, high-nitrogen fertilizer applied in early fall gives grass the nutrients it needs to bounce back from summer stress and build strong roots for winter. Follow product instructions carefully, and avoid over-fertilizing, which can burn grass and encourage disease.

Weeds often take advantage of weakened lawns. Spot-treat problem areas with a selective herbicide or hand-pull weeds to reduce competition for water and nutrients. If your lawn has a thick layer of thatch (more than half an inch), dethatching may be necessary. Thatch can block water and fertilizer from reaching the soil, so removing it allows your lawn to recover more effectively.

New seed and recovering grass need consistent moisture to thrive. Water deeply and regularly for the first few weeks after overseeding and fertilizing—usually about 2–3 times per week, depending on weather. Early morning is the best time to water, as it helps prevent disease and maximizes absorption.

Continue to mow at a higher setting (about 3 inches) and keep mower blades sharp to reduce stress on new and recovering grass. Avoid heavy foot traffic on newly seeded areas until the grass is well established.
