The amount of water your new lawn needs is dependent on the climate, soil, type of turf and its general health. During a period of low rainfall, give your lawn a deep watering a few times a week and a top up lighter watering during a particularly long dry spell. The best time to water is early morning or evening. Try to avoid the hottest parts of the day as this will help minimise water loss due to evaporation.
Wetting agents help water flow freely through your soil. Many Australian soils have poor water retention with some even repelling water. Wetting agents act similarly to detergents by breaking down soil coatings to increase water retention. This means that more water is available to your lawn. Depending on your soil profile, you may need to apply a wetting agent 2 – 3 times per year or more often.
