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.
If moss is a problem (usually only in damp, poorly drained lawns) and you want to get rid of it, try removing with a spring-tined rake first. See our guide to moss in lawns.
