With scorching temperatures already this summer, a strong likelihood of consecutive days above 38C degrees also means dry lightning storms.
Yates horticulturist Angie Thomas said for many gardeners taking precautionary measures to ensure their lawns, trees, flowers and shrubs were still thriving when they return from holidays was crucial.
“If you don’t have a neighbour who can tend to your garden while you’re away you should set up a watering system or soaker hose on a tap timer and mow the lawn before you leave.
“But not too low as longer grass dries out less and stays greener during summer,” she said.
“It’s important to protect trees and plants by spraying them with a protective polymer spray to reduce water loss from the leaves.”
Ms Thomas said a soil wetting agent around the root zone in garden beds would help get water where it was needed.
“To provide slow release nutrients and limit moisture loss you should spread organic plant food and a 5cm layer of organic mulch on garden beds and around trees,” Ms Thomas she said.
She recommended homeowners group potted plants so watering was easy for someone minding the garden, and move tender plants into a shaded spot where they would benefit from natural rainfall.
“Saucers should be placed under delicate potted plants, like hydrangeas, to catch excess water which they can draw on during hot days.,” she said.
“Ensure your indoor collection doesn’t wilt, by gathering them in a well-lit bath or the laundry sink, water them well and place a wet towel under the base of pots to maintain moisture.”
