Experts outline garden heat preparation tips

Experts warn that with a warm spring and expected hot summer, gardeners should start preparing their gardens now. Avoid compacting soil on wet days, as this can hinder water absorption and lead to runoff, according to Liz Rowe, a horticulturalist from Naarm/Melbourne.

Rowe suggests using boards or sticking to paths when stepping into garden beds to prevent soil compaction. She emphasizes that reducing compaction helps retain moisture and supports plant health during dry periods.

Top-dressing with compost or manure can improve soil health without disturbing the soil's natural structure. Experts note that digging disrupts beneficial microbes and bugs that aid in water retention and soil aeration.

Dr. Matthew Parker, director of the Australian National Botanic Gardens, advises using mulch to conserve water and reduce evaporation. The type of mulch should match the garden's needs, with wood-based mulch for perennials and straw-based for annuals.

Parker also recommends increasing grass height and avoiding heavy pruning before heatwaves. He explains that cutting grass too short or pruning plants can increase stress and reduce their ability to withstand high temperatures.

Creating shade with shade cloth or moving potted plants to shaded areas can protect gardens from extreme heat. Experts also suggest using insulating materials around pots to help retain moisture and protect plant roots.
