To protect your lawn during summer, focus on watering deeply in the early morning, mowing with the blades set higher to retain moisture, and applying mulch to insulate the soil. You can also use water-retaining products, aerate the soil, and avoid excessive traffic to help your lawn survive the heat.
Water and moisture
Water in the early morning: This allows the water to soak deep into the roots before the sun evaporates it, and it also helps the lawn recover from any night-time frost damage.
Water deeply: A deep soaking encourages deeper root growth, making the lawn more drought-tolerant.
Apply mulch: A layer of mulch helps the soil retain moisture and regulates its temperature. Your own grass clippings can be used as mulch.
Use water-saving products: Products like hydro-gels can be applied to the soil to help it retain moisture for longer.
Aerate the soil: This helps with water and nutrient absorption by allowing air, water, and nutrients to reach the roots more easily.
Mowing and maintenance
Mow higher: Don’t cut too much grass at once. A higher cut provides shade for the soil, which reduces moisture evaporation and stress on the grass.
Avoid stress: During the hottest period, minimize major lawn maintenance that can cause further stress.
Fertilise cautiously: Limit fertilizing during peak heat as it can stress the grass. A seaweed extract can help thicken cell walls to better withstand heat.
Protection and other tips
Add shade: If possible, increase shade with larger plants or trees.
Reduce traffic: Compaction is intensified by the sun. Avoid excessive foot traffic and move any equipment that is left in one spot for too long.
Clean up leaves: Rake leaves away frequently to ensure the grass gets maximum sunlight.
Consider a colorant: Products like ColourGuard can be used to keep your lawn looking green and healthy during the hot, dry months.
