The Northern Rivers gets plenty of rain, but it arrives unevenly. Long dry spells in spring catch out lawns and new plantings, and summer downpours can leave irrigation running for no reason.
When to water
Early morning is best. The air is cool, the wind is usually light, and leaves dry through the day, which cuts down on fungal problems. Evening watering is second best, though leaves stay wet overnight. Midday watering wastes water to evaporation.
How much
Deep and infrequent beats little and often. A longer soak less often encourages roots to go down. Shallow daily sprinkles keep roots near the surface, where they dry out first. A simple test is to dig a small hole after watering and see how far down the soil is damp.
Sandy soils near the coast
Sandy soil drains fast and holds little water, so plants dry out quickly. Mulch, organic matter and a decent watering routine make a big difference. Heavier soils inland hold water longer, so need less frequent watering.
New plants
Need regular water for the first weeks until they establish. Check them in dry or windy weather, even if the lawn seems fine.
Mulch
A layer of mulch over garden beds keeps the soil cooler, holds moisture and suppresses weeds. It's the cheapest way to cut watering. See weeding and mulching.
Irrigation systems
Check them each spring: blocked or broken heads, heads pointing at the path, and a controller still on a summer schedule through a wet March. A rain sensor stops the system running in the rain. See reticulation checks.
Local rules
Water restrictions can apply in dry periods, and rules differ between councils and water authorities. Check your local council or water supplier's current rules.
Signs you are overwatering
Soggy lawns, yellowing leaves, moss and fungus, and water running onto paths. After heavy rain, switch the controller off for a few days.
