Why Compost Is the Secret to Reviving a Tired Summer Lawn

Another common summer question we get is: “My grass looks dry and patchy — can compost help it recover?” The short answer? Yes. Compost is nature’s way of feeding and healing your lawn — especially during South Africa’s hot, dry months.

1. Compost Rebuilds Tired Soil

During summer, constant watering and heat can strip soil of nutrients. When this happens, grass struggles to stay green and healthy.

Adding Quick Lawn’s Special Compost Mix replenishes the soil with:

• Organic matter for better structure

• Microbes that promote root growth

• Essential nutrients like nitrogen, phosphorus, and potassium

This mix is designed to feed slowly over time, improving soil fertility and helping lawns recover naturally.

2. Compost Helps Your Lawn Retain Water

Summer heat causes water to evaporate quickly from the soil. Compost acts like a sponge — it holds moisture near the roots, reducing water waste and helping grass survive dry spells.

🌿 Pro Tip: Apply compost early in the morning or late in the day to maximise absorption and minimise evaporation.

3. Compost Protects Against Heat Damage

A thin layer of compost (5–10 mm) spread across your lawn acts as a natural sunscreen for your soil. It shades the roots, keeps temperatures cooler, and prevents stress during heatwaves.

This is especially beneficial for Kikuyu, which grows rapidly but can suffer in extreme sun, and LM Berea, which prefers milder, partially shaded environments.

4. Compost Encourages Strong Root Systems

The nutrients in compost promote deeper, more resilient roots. Strong roots mean your lawn can handle drought, foot traffic, and temperature swings far better than untreated soil.

5. How to Apply Compost in Summer

• Mow your lawn slightly shorter than usual.

• Spread a thin, even layer (5–10 mm) of compost across the surface.

• Water thoroughly afterward to help nutrients settle into the root zone.

Avoid piling compost too thickly—it should enrich, not smother, the grass.

6. How Often Should You Add Compost?

For best results, top-dress your lawn twice a year — once in early spring (August–September) and again in mid-summer (December–January). This maintains soil health and ensures your lawn always has enough nourishment to handle seasonal stress.

✅ The Takeaway

Compost isn’t just a soil booster — it’s your lawn’s best defense against heat, drought, and poor growth. By using a quality compost blend, like Quick Lawn’s Special Compost Mix, you can restore colour, thickness, and vitality to your lawn, even in the middle of a scorching summer.

Give your lawn the nourishment it deserves, and enjoy a green, thriving garden all season long.
