How to water your lawn in Melbourne
Most lawns are watered too often and too lightly. Here is how to water deeply, at the right time, and only when your lawn actually needs it.

Most lawns are watered too often and too lightly. Here is how to water deeply, at the right time, and only when your lawn actually needs it.
The golden rule
The single most useful watering habit is to water deeply but less often. A long, soaking water pushes moisture down into the soil and trains roots to follow it, building a deep root system that rides out hot, dry spells. Frequent light sprinkles do the opposite: they keep roots shallow and lazy, sitting near the surface where the soil dries first.
In practice that means one or two good waterings a week through summer rather than a daily splash. The aim is to wet the soil to roughly 10 to 15 centimetres, then let the top dry out before the next round.
Timing
Early morning is the best time to water, before the sun is high. The lawn drinks before evaporation steals it, and the leaf dries through the day, which reduces the disease risk that comes with sitting wet overnight. Watering in the middle of a hot afternoon wastes a large share to evaporation and can stress the grass further.
This matters most on the open, full-sun blocks we mow around Fawkner, Hadfield and Campbellfield, where exposed kikuyu and couch dry out fast and an afternoon water mostly disappears into the air.
How much
Soil type changes everything. Sandy soils drain quickly and want shorter, more frequent watering. Heavier clay soils, common across the inner-north, hold water far longer and can be watered less often but for longer each time, letting it soak in slowly rather than running off.
A simple test: push a screwdriver into the lawn after watering. If it slides in easily to a hand's depth, you have watered enough. If it stops short, the water has not penetrated and the roots will stay shallow.
Working with the rules
Melbourne's permanent water saving rules shape when and how you can water, and tighter restrictions can apply in dry years, so it is worth checking the current rules with your retailer before you set a routine. The good news is that deep, infrequent, early watering is also the most water-efficient approach, so doing it right keeps you on the right side of the rules anyway.
Across shadier gardens like those we tend in Strathmore and Moonee Ponds, lawns under heavy tree canopy need far less water than open blocks, so the same schedule rarely suits both.
Signs and new lawns
A thirsty lawn gives clear signals before it browns off. The colour dulls to a grey-blue, footprints stay pressed into the grass instead of springing back, and the leaf blades fold or curl. Catch it at that stage and a good water brings it back. Let it go and you are into recovery rather than maintenance.
Newly laid turf or freshly seeded lawns are the exception to the deep-and-infrequent rule. They need light, frequent watering to keep the surface moist while roots establish, then you gradually stretch the intervals and increase the depth over a few weeks until the lawn is on a normal mature schedule.
