A newly laid turf lawn needs to grow a new root system so it’s essential to keep the soil on the back of the turf and the soil below moist for up to four weeks while it establishes. Try not to walk on your lawn at this time. During the spring and autumn, the turf will require much less watering than in summer. In warm, dry summer months a new turf lawn may require watering twice a day for the first week, then 2-3 times a week and then once a week. The aim is to keep the turf moist but don’t overwater as this can cause shallow rooting and encourage weeds. Using a sprinkler is the best way as it waters evenly but make sure you don’t leave it in the same position for more than 15 minutes or you will over water.
It’s a good idea to test the turf to see if it’s wet enough. You can either cut a small hole and check or stick a knife through the turf into the soil and if goes in easily and comes out clean you know the soil is moist. Once your lawn reaches 5cm, probably 10 days or so after it was laid, you can mow with the blades set high. Frequent mowing will encourage a denser lawn with fewer weeds.
Feeding is best in spring and autumn with a lawn fertiliser and once the lawn is established you can use products like Westland Aftercut if you feel it needs greening up. An established lawn can survive with no watering so it then becomes a personal preference. If you want a lush green lawn all year then you’ll want to water in the summer but if you don’t mind it going brown in very hot or dry weather then just leaves it to look after itself. A well-established lawn with a good root system will always bounce back.
