You need to water your lawn to supply the right amount of moisture, cool down the soil temperature and wash fertilisers into the soil. As clay soils hold moisture for longer than sandy soils, you’ll need to water grass planted in sandy soils more frequently. However, clay may hold onto water more intensely, preventing your lawn from utilising that high moisture content. Loam is the ideal soil mix and will retain just the right amount of water, while still releasing enough moisture.
If you have loamy soil with a warm season grass, give your lawn a good soaking of water once a week, and perhaps just cool it off if the grass is under stress from extreme heat. The norm is 25mm of water per week. Place a container in each of the sprinkler zones and determine how long it takes to fill the container up to 25mm. This is the amount of time you’ll have to irrigate each zone once a week. It’s better to give more water in one session to force the roots to grow down to a deeper level, than giving a little water every day.Cool season lawns need more frequent, shallower watering, as their root systems are not as deep as some of the warm season lawns.
Water early in the morning as this is the coolest time of the day and there will be less evaporation. You’ll lessen the chances of your lawn contracting a disease if it dries before nightfall.
Water spots where pets have urinated immediately, or at least more frequently, using a watering can or hose.
*Tip An easy way to tell if your lawn needs water is to walk on it. A healthy lawn feels soft under your feet. If the lawn feels crusty and it breaks when you rub your hands over the top of it, it’s not getting enough water.
