Watering Tips

Summer Watering (Established Lawns)

Most New Zealand lawns are cool‑season grasses and need consistent watering through summer.

Water your lawn every 2–3 days, depending on temperature and rainfall. Avoid watering daily unless establishing a new lawn or during extreme heat.

Each watering should apply enough water to reach the root zone. Aim for 10–15 mm per session. Because sprinklers and water pressure vary, place a flat‑sided container (such as an ice‑cream container) on the lawn to work out how long your sprinkler needs to run.

Water in the early morning when possible. This improves efficiency and helps reduce disease, particularly in fine fescue and browntop lawns.

Watch the lawn for signs it needs water. If footprints remain flattened or the grass looks dull in colour, plan to water the next scheduled day.

Dry or brown patches can usually be recovered with regular watering. For stubborn areas, use a garden fork to punch holes to help water soak in. Wetting agents can also assist with problem spots.

Avoid mowing lawns that are under severe heat or moisture stress. Keeping the mower set higher during summer helps protect the lawn and reduce water loss.

Watering New Lawns

New lawns require lighter, more frequent watering until roots are established.

Keep seed consistently moist during germination and do not allow it to dry out.

Water 2–3 times per day using light applications to keep the surface damp without water pooling.

After approximately 3 weeks, gradually reduce watering frequency and move toward the every 2–3 day watering cycle used for established lawns.
