When a Queensland heatwave approaches, the garden can become a source of heat and stress for plants and people alike. Preparing the garden in advance reduces the risk of heat damage and keeps the space comfortable to use. A few simple steps can make a big difference to how the garden feels during the hottest days.
Shade the Plants
Covering plants with shade cloths or natural shade can lower the temperature around the foliage. Using lightweight fabric that is loosely tied to stakes allows air to circulate while blocking direct sun. Remove the cloths when the heatwave subsides to let plants recover their normal light exposure.
Planting taller trees or installing pergolas creates a natural canopy over beds and pathways. The shade from these structures keeps the ground cooler and reduces evaporation. When selecting trees, choose species that are native and well adapted to the local climate.
Use shade cloths on sensitive plants. Tie cloths loosely to allow airflow. Install pergolas over key areas. Choose native trees for lasting shade.
Watering Early
Watering plants in the early morning provides moisture before the heat rises. The soil absorbs the water efficiently when temperatures are lower. This practice reduces the need for frequent watering during the day.
Apply a thick layer of mulch around plant bases to retain moisture and keep roots cool. Mulch also suppresses weed growth and stabilises soil temperature. Replenish the mulch if it becomes compacted or eroded during the heatwave.
Water early in the day.
- Apply mulch around plants.
- Replenish mulch when needed.
- Check soil moisture regularly.
Prune and Trim
Pruning branches that are too close together improves airflow through the canopy. Better airflow reduces the build-up of heat and dampness around leaves. Trim back any dead or damaged branches to prevent pest attraction.
Use sharp, clean tools to avoid tearing the bark. Cut at a slight angle to encourage healing and reduce water loss. Dispose of cuttings in a rubbish bin to keep the area tidy.
- Prune for better airflow.
- Trim dead branches.
- Use clean tools.
- Dispose of cuttings properly.
Protect the Lawn
Mowing the lawn to a higher cut keeps the grass blades longer, which shades the soil. Longer grass also retains moisture and reduces the rate of evaporation. Avoid cutting the grass too short during the heatwave to keep the roots cool.
If the lawn is heavily used, consider laying a thin mat of grass seed or turf mulch to reduce wear. This layer protects the soil from direct sun and keeps it cooler for the roots. Reapply the mulch after a few weeks if it becomes uneven.
Mow to a higher cut. Lay turf mulch if needed.
Maintain the Water Source
Check that the garden hose is free from kinks and leaks before the heatwave begins. A well-connected hose ensures quick access to water when plants need a drink. If the hose is damaged, replace it to avoid wasted water.
Secure the hose in a neat coil to prevent it from becoming tangled or damaged by heat. Keep the coil in a shaded spot, such as under a tree or a pergola, to protect it from the sun. Use a hose clamp to keep the connection tight and prevent leaks.
Secure hose in a coil.
- Check hose for kinks.
- Store hose in shade.
- Use hose clamp.
Clear the Drainage
Ensure that the garden drains freely by checking that gutters and downpipes are clear of debris. Clogged drainage can lead to puddles that heat up and cause root rot. Clean any blockage with a brush or a small scoop.
If the drainage area is prone to waterlogging, add a layer of gravel to improve flow. Gravel also helps to keep the surface loose and reduces the heat reflected onto the soil. Inspect the drainage after a rain to confirm it is working properly.
- Check gutters for debris.
- Add gravel if needed.
- Inspect drainage after rain.
Plan for Shade Structures
If you plan to install a shade sail or a pergola, do so before the heatwave starts. Setting up the structure early allows you to adjust the angle or position for maximum shade. Use sturdy posts and secure them firmly to the ground to withstand wind.
If the structure is large, consider hiring a professional to handle the installation safely. A professional can ensure that the posts are level and that the frame is stable. After installation, check that the shade does not block essential pathways.
Adjust angle for maximum shade. Hire a professional if needed.
By taking these steps before a Queensland heatwave, you can protect your garden and keep it comfortable for everyone to enjoy. A little preparation goes a long way in keeping plants healthy and the backyard inviting during the hottest days.
