Best Practices for Watering Your Lawn During New Zealand’s Dry Spells

Keeping your lawn green during dry weather can feel like a full-time job, can’t it? Long, hot days and little rain often leave lawns looking brown and patchy. But with proper watering habits, you can help your grass survive and even thrive through New Zealand’s dry spells.

In this article, we’ll walk you through simple, water-smart strategies that make lawn care easy and effective. You’ll learn how to give your lawn just what it needs without wasting a drop. Let’s get started.

7 Best Practices for Watering Your Lawn During Dry Spells

Keeping your lawn green during dry spells is about using water smartly. Here are some practical tips to help you keep your grass healthy without wasting water:

1. Water Early in the Morning

When you water in the middle of the day, most of it disappears into the air before your grass can absorb it. The sun is too intense. Instead, try watering early in the morning, between 6:00 a.m. and 10:00 a.m. At this time, the air is cooler, the ground absorbs water better, and there’s less evaporation. Also, your lawn will have time to dry before nightfall, which helps prevent diseases caused by damp grass.

2. Water Less Often but More Deeply

It might feel right to water a little every day, but shallow watering only encourages your grass roots to stay near the surface. That makes them weak and thirsty. You should give your lawn a good soak once or twice a week. It means watering until the soil is moist, approximately 10–15 cm deep. Deep watering helps roots grow deeper and makes your lawn stronger when the weather gets hot and dry.

3. Test Your Lawn Before Watering

Don’t just water on a schedule. Check if your lawn needs it. Push your finger or a screwdriver into the soil. If it’s hard and dry about 10 cm down, it’s time to water. But if it still feels damp, your lawn is doing fine. The simple test helps save water and prevents your lawn from becoming soggy.

4. Avoid Watering at Night

It’s tempting to water in the evening when things cool down, but leaving your lawn wet overnight encourages mould and fungal problems. Morning watering is always better. If mornings are challenging, early evening (before 6 pm) is the next best option, allowing your lawn time to dry.

5. Know Your Grass and Soil

Different types of grass need different care. If you have cool-season grass, such as ryegrass or fescue, you’ll likely need to water more frequently, possibly every 3–4 days during a dry spell. Warm-season grasses, such as kikuyu or couch, are tougher and may only require watering once a week. Also, pay attention to your soil. Clay holds water longer, allowing you to water less frequently. Sandy soil drains quickly, so you may need to water more regularly.

6. Use the Right Tools

Dragging a garden hose around works, but it’s not the most efficient method. Using a sprinkler system, a soaker hose, or a hose with a spray nozzle helps you water evenly and avoid overwatering. Timers are great too. They ensure your lawn receives the right amount of water, even if you’re busy or away.

7. Save Water with Rain Barrels

Setting up a rain barrel or tank lets you collect rainwater from your roof. You can use it to water your lawn during dry spells, which helps reduce your water bills. It’s better for the environment, too. Just check your local council’s rules about water use during restrictions.

But with choosing the proper watering schedule, understanding your grass type, and avoiding common mistakes, it’s easy to feel overwhelmed. That’s where you need professional support to make life easier for you.
