Melbourne gardens are feeling the effects of a long, hot summer, with dry soil, stressed plants and lawns struggling to stay green. Extended heat draws moisture out of the ground quickly, meaning even established plants can become dehydrated if watering isn’t adjusted.
Best times to water
The most effective time to water is early morning (before 9am). This allows moisture to soak into the soil before the heat of the day causes evaporation. Evening watering can also help, but avoid late-night watering as constantly damp soil can encourage disease.
How often to water
-
Lawns: 2–3 deep waters per week rather than daily light sprinkles
-
Garden beds: Every 2–4 days during extreme heat, depending on soil type
-
Pots and containers: Check daily — they dry out much faster
-
New plants: Require more frequent watering until established
Helpful tips during heatwaves
-
Water deeply so roots grow down, not just near the surface
-
Apply mulch to retain moisture and protect soil
-
Use a watering can or drip irrigation to target the base of plants
-
Avoid watering leaves in full sun to prevent scorch
With consistent, deep watering and a few smart adjustments, Melbourne gardens can recover quickly and stay healthy through the tail end of summer.
