HOW TO WATER YOUR LAWN PROPERLY IN ADELAIDE DURING SUMMER
JANUARY GUIDE
January is one of the hottest months of the year in Adelaide, and how you water your lawn can make a big difference to how well it holds up through summer.
Many lawns struggle during this time, not because they aren’t being watered, but because they’re being watered the wrong way. Light, frequent watering is one of the fastest ways to weaken a lawn. It encourages shallow roots that sit near the surface, leaving the grass more vulnerable to heat stress and drought.
How to Check If Your Lawn Actually Needs Water
Before you turn on the sprinkler, it’s worth checking whether your lawn needs water.
Here are two simple methods:
- The Footprint Test: Walk across your lawn. If the grass springs back up quickly, it probably doesn’t need water yet. If the footprints stay down, the lawn is under stress and needs watering.
- Visual Signs: Look for a bluish-grey tint to the grass, wilting, or the lawn feeling spongy underfoot. These are early signs that your lawn needs water.
Checking first helps prevent both underwatering and overwatering.
How Much Water Does Your Lawn Need?
As a general guide, most established lawns in Adelaide need approximately 25–35mm of water per week during summer.
Rather than applying this all-in-one go, we recommend splitting the weekly requirement over 2 or 3 watering sessions per week. This approach works well for most Adelaide lawns and soil types.
Why 2–3 Watering Sessions Per Week is Better:
- It allows better water penetration, especially on Adelaide’s clay soils
- It reduces the risk of water running off before it can soak in
- It strikes a good balance between keeping the lawn healthy without overwatering
Example: If your lawn needs around 30mm of water per week, you could apply roughly 10–15mm per watering session, 2 or 3 times per week.
How to Measure Your Watering
To work out how long your sprinkler needs to run, place an empty small tuna tin (or any straight-sided container) on your lawn while the sprinkler is running. Time how long it takes to collect the desired amount of water. This gives you a reliable guide for future watering sessions.
Best Time of Day to Water in Adelaide
The best time to water your lawn is early in the morning, ideally before 9am. This allows the water to soak into the soil before the heat of the day causes high evaporation.
Avoid Watering:
- In the middle of the day (high evaporation loss)
- Late in the evening (can promote fungal diseases in warm, humid conditions)
Common Watering Mistakes to Avoid
Many Adelaide homeowners make these mistakes during summer:
- Watering every day regardless of need
- Applying light, frequent watering (encourages shallow roots)
- Overwatering, which can lead to yellowing, thatch buildup, and disease
- Not adjusting watering after rainfall
Deep, infrequent watering (split over 2–3 sessions per week) encourages roots to grow deeper into the soil, making your lawn more resilient during hot, dry periods.
