Heatwave Lawn Care: How to Prevent Grass from Drying Out & Dying

Extreme heatwaves can wreak havoc on your lawn, turning once-green grass into a dry, brittle mess. With proper care, you can prevent heat damage and keep your lawn hydrated and healthy.

1. Water Smartly & Efficiently

• Water deeply (1–1.5 inches per week) to encourage deep roots.
• Water early in the morning or late evening to reduce evaporation.

2. Raise Mowing Height

Keeping grass longer (around 3 inches) provides shade for the soil and reduces water loss.

3. Avoid Mowing During Peak Heat

Cutting grass in extreme heat can stress it further. Mow in the early morning or evening when temperatures are cooler.

4. Apply a Moisture-Retaining Lawn Feed

Drought-tolerant fertilisers with high potassium levels help grass retain moisture and strengthen roots.

5. Reduce Foot Traffic & Lawn Use

Dry, heat-stressed grass is more susceptible to damage. Limit activity on your lawn during extreme heatwaves.

6. Mulch Grass Clippings

Leave grass clippings on your lawn after mowing to help retain moisture and provide essential nutrients.

7. Consider Drought-Resistant Grass Types

If your lawn consistently struggles in summer, consider reseeding with drought-resistant grass varieties like fescues or ryegrass.

With the right care, you can protect your lawn during heatwaves, ensuring it remains green, healthy, and resilient even in the hottest weather.
