How to Manage Your Lawn in Late Summer – Keep Your Grass Healthy & Resilient

As summer comes to an end, high temperatures, dry conditions, and foot traffic can leave your lawn looking stressed, patchy, or discolored. Proper lawn care in late summer is essential to prevent damage, maintain strong root systems, and prepare for the cooler months ahead.

1. Adjust Your Mowing Routine

✅ Raise the Mowing Height

• Keep grass around 3-4 inches tall to provide shade for the soil and retain moisture.
• Taller grass reduces weed growth and prevents sun scorch.

✅ Sharpen Mower Blades

• Dull blades tear grass instead of cutting it cleanly, causing stress and discoloration.
• Sharpen blades regularly to maintain smooth, even cuts.

✅ Follow the One-Third Rule

• Never cut more than one-third of the grass blade at a time to avoid shocking the lawn.

2. Water Wisely to Prevent Drought Stress

✅ Deep, Infrequent Watering

• Water early in the morning (between 6-10 AM) to reduce evaporation.
• Provide about 1 inch of water per week, including rainfall, for deep root hydration.

✅ Use Soaker Hoses or Drip Irrigation

• These methods deliver moisture directly to the root zone, preventing water waste.

✅ Monitor Soil Moisture

• Dry soil becomes compacted and repels water—aerate if necessary to improve absorption.

3. Aerate & Dethatch for Stronger Roots

✅ Core Aeration

• Helps break up compacted soil, improving airflow, water penetration, and root development.
• Best done in late summer to early fall for maximum benefit.

✅ Dethatching

• Removes the layer of dead grass and organic debris that blocks nutrients and water from reaching the soil.

✅ Overseed Bare Patches

• Apply heat-tolerant grass seed to fill in thin or damaged areas.
• Cover with topsoil or compost for improved moisture retention and germination.

4. Fertilize for End-of-Summer Strength

✅ Choose a Slow-Release Fertilizer

• Apply a nitrogen-rich fertilizer to encourage deep green growth and root strength.
• Avoid over-fertilizing, as excessive nitrogen can weaken grass before fall dormancy.

✅ Organic Options for Soil Health

• Compost tea, seaweed extract, or natural fertilizers boost microbial activity and improve nutrient absorption.

✅ Apply Lime If Needed

• If your soil is too acidic, adding lime can balance pH levels, ensuring better nutrient uptake.

5. Prevent Weeds & Lawn Diseases

✅ Pre-Emergent Weed Control

• Applying a pre-emergent herbicide can stop fall weeds like crabgrass and dandelions before they sprout.

✅ Treat Brown Patches & Lawn Fungus

• Excess moisture from humidity can cause fungal diseases like dollar spot or brown patch.
• Use aeration, proper watering, and fungicides to manage outbreaks.

✅ Maintain Proper Drainage

• Ensure that water does not pool in certain areas, as standing water can invite pests and lawn diseases.

The Result: A Healthy, Resilient Lawn Ready for Fall

By following these late summer lawn care steps, your grass will stay strong, green, and prepared for the changing season. With proper mowing, watering, fertilization, and aeration, you can maintain a lush, vibrant lawn that thrives year-round.
