Heatwave help for gardens
During summer heatwaves, we can head to the beach, hang out in a cool shopping centre or crank up the aircon at home. But our garden plants can’t avoid the sun’s summer rays.
When the temperature soars, there are steps we can take to ensure our gardens survive a summertime heat blast.
1. Magic mulch
Well before the mercury rises, make sure your garden has an adequate layer of mulch, which allows water to penetrate the soil but reduces evaporation.
2. Water wise
When forecasters predict a scorcher, give your plants a drink in the evening or early morning, so the water can soak into the soil before the blazing sun bakes the ground. If you water in the middle of the day, much of the moisture will be lost to evaporation.
Aim the water at the roots rather than wasting it on foliage. A deep watering is better than a surface splash because it encourages roots to grow deeper in the soil where they’re sheltered from the sun.
Water lingering in a garden hose in the summer heat can be hot enough to make coffee. If you choose to irrigate when the sun’s up, first squirt the superheated hose water away from any plants so you don’t scold them.
3. Shelter and shade
Sensitive plants may need protection to prevent leaf burn. Erect a temporary shelter or stick a beach umbrella in the ground, but remember to rotate it as the sun moves across the sky.
Pots don’t hold much soil, so it’s important to water potted plants well to ensure they make it through the heat of the day. If possible, move them to a shaded area to relieve some of the heat stress, but try to keep them off hot surfaces like cement.
Remember, while you’re taking care of your gorgeous garden, look after yourself by following the five tenets of skincare – slip, slap, slop, seek and slide.
