Summer Lawn Care Tips for Melbourne

Keep your lawn thriving through Melbourne's hottest months.

Summer Guide

Protecting Your Lawn in the Heat

Melbourne summers can be brutal on lawns, with temperatures often exceeding 40Â°C and extended dry periods. The key to a healthy summer lawn is preparation, proper watering, and adjusting your maintenance routine to reduce stress on the grass.

Many homeowners make the mistake of treating summer like any other season, but your lawn's needs change dramatically when temperatures rise. Understanding these changes is the first step to keeping your lawn green while your neighbours' lawns turn brown.

Watering Strategy

Smart Watering in Summer

Proper watering is crucial during hot weather

☀️

Water Early Morning

Water between 6am and 9am before the heat sets in. This gives grass time to absorb moisture before evaporation accelerates. Evening watering can promote fungal disease as water sits on blades overnight.

ðŸ’§

Deep & Infrequent

Water deeply 2-3 times per week rather than lightly every day. Apply 25-30mm per session to encourage deep root growth. Shallow watering creates shallow roots that struggle in drought conditions.

ðŸŽ¯

Check Soil Moisture

Push a screwdriver into the soil - if it goes in 15cm easily, you don't need to water. If soil is hard and dry, it's time to irrigate. Different soil types in Melbourne's west hold moisture differently.

Watch for Stress Signs

Grass showing a blue-grey tint or footprints remaining visible after walking are signs of water stress. Address these early before permanent damage occurs. Brown patches may not recover.

Mowing Adjustments

Summer Mowing Heights

Taller grass means healthier grass in summer

Raise Your Cutting Height

During summer, increase your mowing height by 25-50%. For Buffalo grass, this means cutting at 50-60mm instead of the usual 35-40mm. Couch and Kikuyu should be maintained at 30-40mm rather than 20-25mm.

Taller grass provides several benefits: the blades shade the soil, reducing moisture loss and keeping roots cooler. Longer leaves also mean more photosynthesis capability, helping grass recover from heat stress.

Mowing Frequency

You may need to mow less frequently in summer as growth slows during extreme heat. Never remove more than one-third of the blade length in a single mow. If grass has grown tall, reduce height gradually over multiple sessions.

Sharp Blades Matter

Dull mower blades tear grass rather than cutting cleanly, creating more surface area for moisture loss and entry points for disease. Sharpen blades at least twice during the summer season.

Heatwave Survival

During Extreme Heat Events

Special care when temperatures exceed 40Â°C

Stop Mowing

Don't mow during heatwaves. The stress of cutting combined with extreme temperatures can permanently damage or kill grass. Wait until temperatures drop below 35Â°C to resume mowing.

Stay Off the Lawn

Minimize foot traffic on stressed lawns. Heat-stressed grass is more susceptible to damage, and footprints may remain visible for weeks. If possible, avoid the lawn entirely during extreme heat.

Emergency Watering

If restrictions allow, a light spray during the hottest part of the day can cool grass by several degrees. This isn't for hydration - it's to prevent heat damage. Just a few minutes can help.

Common Problems

Summer Lawn Issues

Identifying and addressing heat-related problems

Brown patches in summer are usually drought stress, not disease. Check soil moisture first. If soil is dry, increase watering. If soil is moist but grass is still brown, look for lawn grub damage - summer is peak season for Army Worm and Web Worm.

Warm-season grasses like Couch and Kikuyu may go dormant during extreme drought conditions. This is a survival mechanism, not death. The grass will green up when conditions improve. Maintain minimal watering to keep roots alive.

Scalping occurs when mower is set too low, exposing stems and soil. Combined with summer heat, this can burn the lawn. Raise mower height immediately. The grass should recover in 2-4 weeks with proper care.

Summer brings increased insect activity. Look for spongy, dead patches (lawn grubs), chewed grass blades (caterpillars), or brown circles (mole crickets). Apply appropriate pest treatments in the evening when pests are active.
