Your new lawn does not need immediate lawn fertiliser, but it will require plenty of water. Too little water can cause a series of problems and affect the grass growth. If the fresh turf doesn’t receive enough water the turf will shrink and form gaps. Exposing the topsoil beneath.
It takes only a few hours for new turf to dry out and be damaged without water.A new lawn will require aftercare and watering twice a day for the first 10-14 days. It will require more in warm weather than in spring or autumn. Then 2-3 times a week until its fully established. The best method we have found to evenly water the new turf is with a Hozelock oscillating sprinkler.
The sprinkler may have to be moved around a few times during watering. Make sure its covering the whole area. If any areas are not getting watered , for example in the corners, then you must make sure to water those parts by hand with the hose pipe. The best way to determine if your turf soil is wet enough is to fold back a corner of the turf and make sure the soil underneath is moist.
