How to Keep Your Garden Thriving in Hot & Dry Conditions
Auckland summers are made for enjoying the garden, enjoying long evenings dining outdoors in lush green spaces. But heat, dry spells, strong sun and sudden weather changes can quickly stress plants if gardens are not cared for correctly.
This ‘summer garden care guide’ is designed specifically for Auckland conditions, helping homeowners protect their investment and keep gardens looking beautiful right through the hottest months.
Why Summer Garden Care is so Important in Auckland
Auckland's summer climate creates a unique set of challenges:
• Periods of intense heat and drying winds
• Water restrictions during dry spells
• Heavy rain events that compact soil and wash nutrients away
• Increased pest and disease activity
Without the right care, gardens can quickly decline. Lawns burn off, plants wilt, and weeds take over. Consistent, professional maintenance makes all the difference.
Smart Watering: Less Often, More Effectively
1. Water Deeply, Not Frequently
Shallow watering encourages weak root systems, instead:
• Water early in the mornings
• Apply water slowly and deeply
• Allow soil to dry slightly between watering
This encourages deeper roots and better drought tolerance.
2. Check Irrigation Systems Regularly
Summer is when irrigation issues show up fast.
• Look for blocked or misaligned sprinklers
• Ensure even coverage across lawns and garden beds
• Adjust timers as temperatures rise
Even small faults can lead to stressed plants or wasted water.
Mulching: Your garden's Best Summer Defense
3. Refresh Mulch Before Peak Heat
Mulch plays a critical role in summer garden health by:
• Retaining moisture
• Regulating soil temperature
• Suppressing weeds
• Improving soil structure over time
Apply mulch around plants (without touching stems) to help gardens cope during hot, dry periods.
Pruning & Plant care in Summer
4. Light Pruning Only
Summer is not the time for heavy pruning.
• Remove dead, damaged or diseased growth
• Lightly shape hedges if needed
• Avoid aggressive cuts that expose plants to sunburn
Proper pruning helps maintain form while reducing plant stress.
5. Support Plants Under Stress
Signs of heat stress include wilting, leaf scorch and premature leaf drop.
• Stake or support vulnerable plants
• Increase mulch depth
• Provide temporary shade if needed
Early intervention prevents long-term damage.
Lawn Care During Auckland Summers
6. Raise Your Mowing Height
Cutting lawns too short exposes soil and roots to heat.
• Keep grass slightly longer
• Mow regularly but avoid scalping
• Ensure mower blades are sharp
Longer grass shades soil and retains moisture.
7. Feed Carefully & Water in Fertiliser
Avoid heavy fertilising in peak heat.
• Use slow-release products if needed
• Focus on soil health rather than rapid growth
• Always water lawns thoroughly after fertiliser application to prevent burning and help nutrients reach the root zone
Overfeeding during summer can weaken lawns and burn plants.
Weeds, Pests & Disease: Stay Ahead
8. Remove Weeds Early
Weeds compete for water and nutrients
• Remove while small
• Focus on garden edges and lawn borders
Mulching and healthy soil reduce weed pressure.
9. Watch for Summer Pests
Warm weather increases pest activity.
• Check undersides of leaves
• Look for discolouration or leaf damage
• Address issues early with targeted treatments
Healthy gardens are naturally more resistant to pests and disease.
Preparation for Late Summer & Autumn
Summer is the perfect time to:
• Assess plant performance
• Identify areas needing improvement
• Plan autumn planting and landscaping upgrades
Autumn is one of the best seasons for new garden work in Auckland.
