How to water a new lawn

Our watering guide covers the first few weeks after spraying, when your new lawn needs short, frequent watering, and how to ease off as it establishes.

FAQ

Process questions

How long until I can walk on it?

You'll see green in about 7–10 days. Light foot traffic is fine after roughly 4 weeks, and most lawns are ready for their first mow at around 6 weeks.

Is hydroseeding as good as turf?

Once it's established, yes – and often better. Because the grass grows from seed in your own soil, the roots go deeper and there are no seams. The trade-off is time: turf looks finished on day one.

What time of year is best?

Spring and early autumn are ideal in Perth, when the soil is warm and the heat is manageable. We can spray at other times with the right mulch and blend, as long as the lawn gets enough water while it establishes.

How much watering does it need?

Light, frequent watering for the first few weeks, usually a few short sessions a day. Water Corporation's new-lawn exemption lets you water outside your rostered days while it establishes.

What prep does my yard need?

Bare, level soil that's free of weeds and rubble, with a wetting agent worked into water-repellent sand. If your yard isn't there yet, we can take care of the prep for you.

Will it wash away in rain?

The mulch and a natural tackifier bind the seed to the soil, so normal rain helps rather than hurts. A very heavy storm in the first couple of weeks can wash patches on slopes, which is why we time the spray around the weather where we can.
