Watering Frequency: The Basics

How Often Should You Water?

• Spring/Autumn: 2–3 times per week
• Summer: 3–4 times per week (daily during heatwaves)
• Winter: Once every 1–2 weeks, or not at all in cooler climates

Deep watering less often beats shallow watering daily. Aim for the water to soak 10–15cm into the soil.

How Long Should You Water?

• Sprinkler system: 20–30 mins per session
• Drip irrigation: 45–60 mins
• Hand watering: Until soil is evenly moist but not soggy

Irrigation output cheat sheet

Device	Typical output	Scheduling example to reach ~25 mm
Pop-up spray heads	25 to 40 mm per hour	40 to 60 minutes weekly. Split into 2 sessions in hot weather.
Rotary/rotor heads	10 to 20 mm per hour	75 to 150 minutes weekly. Split into 2 or 3 sessions.
Drip/micro irrigation	Low. focused delivery	Longer runtimes. excellent during restrictions and for slopes or narrow strips.

Clay soil needs slower. longer sessions to avoid runoff. Sandy soil needs shorter. more frequent sessions. Loam sits in the middle.

Check soil with a screwdriver. If it pushes in easily, you’re good.

Best Time of Day to Water

• Early morning (4am–9am) is best. It lets water soak in before the heat.
• Avoid evenings: moisture lingers, inviting fungal problems.
• Midday watering wastes water due to evaporation.

Use a hose timer or automated irrigation system to make mornings easy.

Compliance tip. Many NSW areas allow watering lawns and gardens before 10am and after 4pm when using an appropriate hose or system. Always confirm current rules with your local authority.

Set automation for early morning. For example. start at 5.00am to avoid wind and reduce evaporation. If winds are strong. postpone your schedule to the next calm morning.

Seasonal Adjustments by Region

Queensland (Hot, Humid)

Water more frequently during summer, even daily in dry inland areas. In coastal areas, humidity helps. 2–3 times per week is often enough. Use wetting agents like EasyGreen’s Lawn Care Kits to combat hydrophobic soils.

New South Wales (Mixed Climate)

In Sydney and surrounds, stick to 2–3 times weekly spring/summer. Watch for water restrictions. Use drippers or hoses with triggers. Winter usually needs no watering, especially if rain is regular.

Victoria (Cooler, Seasonal)

Lawns go dormant in winter. Hold off watering unless there’s a drought. Spring and autumn: 1–2 times weekly. Summer: 3 times per week or more during heat spells.

Watering a New Lawn

Newly laid turf needs more frequent, shallow watering.

• Week 1–2: Light watering 2–3 times daily
• Week 3–4: Once per day, deeper soak
• Week 5 onward: Start transitioning to normal schedule (2–3 times per week)

Don't let it dry out while rooting. Use a wetting agent if water pools or runs off.

Water-Smart Tips (And Compliance)

• Use a wetting agent monthly to improve water absorption.
• Mulch clippings to reduce moisture loss.
• Install a hose timer to stay consistent.
• Group lawn zones for even coverage using drippers or pop-up sprinklers.

Check your local council for watering days and hours. Especially in Sydney, Brisbane, or Melbourne where restrictions apply.
