After Care Advice.
Between March and October, newly laid turf should be well-watered within half an hour of laying. Ensure enough water has been applied by lifting a piece of turf to check if the water has soaked right through and into the soil below.
The watering should be repeated at least once a day over the entire area until the grass roots make the turf difficult to pull off the soil. It is hard to over-water the lawn at this stage and any browning will nearly always be the result of turf drying out too much.
First use of lawn
You will find that the surface is fairly soft for a week or two after the turf is laid due to the soil being disturbed and the heavy watering. It is better to keep off the grass at this stage to avoid surface damage. As the roots establish, the surface will harden up and will take more foot traffic without sinking, so the best rule is to increase your use of the lawn gradually.
Wait until your new lawn has started to root before the first mow. This can be checked by lifting a corner of a turf to see if the roots are attached to the soil below.
Set the mower to a fairly high setting at first to avoid stress to the grass. Mow once or twice per week if needed, but do not remove more than one-third of the grass height at each cut.
Over a few weeks, the height of cut can be reduced to an ideal height of between 15mm and 35mm. (approx three quarters of an inch to one and a half inches). Longer grass will be harder wearing and usually appear greener while a shorter cut will produce a finer grass leaf. However, if the mower blade scalps the ground or cuts too short, brown patches will appear.
