Heatproof the backyard

 

It’s not just the greenery that needs protection. When you’re outdoors, avoid the hottest times of the day and follow sun-safe guidelines.

Evaporation causes moisture loss from soil, especially on hot, windy days but spreading a layer of mulch at least 20mm thick for fine mulches and up to 80mm for coarser material can reduce it.

 

Mulch acts as a blanket by shielding soil from sun and wind, and is especially important for plants with shallow or delicate root systems such as citrus, camellias and azaleas. Most vegies benefit from mulch protection that also keeps pests away.

Many plants that do well in dry conditions are native to the hostile Australian environment. Some have characteristics to help them

conserve water and reflect heat such as silver or grey foliage, waxy or shiny leaves, small or hairy leaves.

 

The cactus is a heat-friendly plant with spines of modifi ed leaves that don’t lose water through evaporation.
