See our guide to spring/summer lawn care.
Avoid walking on or mowing newly sown grass until it has reached 5–8cm (2–3in) tall. Even then, only give it a light trim, with the blade at the highest setting.
A flush of weed seedlings appearing in a newly sown lawn is nothing to worry about. They will disappear once regular mowing begins.
Water new lawns (either from turf or seed) in dry spells to make sure they establish well.
Wait until at least September if you want to lay turf, as it won’t establish well if laid now and may die in a hot, dry summer. It will settle in much better during the autumn.
See our video guide to creating a new lawn.
In a hot summer keep your lawn a little longer than usual. Also consider leaving the clippings on the lawn, as a mulch, to help hold in moisture. See our advice on lawn care in droughts.
