Lawns

Mow regularly and continue adding clippings to the compost heap.

Keep the lawn edges trimmed.

Use the half-moon edging iron, or a spade, to create a 7.5cm (3in) gutter around the lawn edge. This will prevent grass from creeping into the border from the main lawn.

Apply a high nitrogen summer lawn fertiliser to encourage a healthy-looking lawn, taking care to avoid any runoff as this may cause pollution. Always follow the manufacturer's instructions carefully.

Sowing new lawns or over-seeding dead patches can still be carried out in early May. Prepare the ground for sowing, by cultivating, levelling and lightly firming beforehand. Do not walk over or mow newly sown grass until it has reached a height of 5-7.5cm (2-3in), and then only give it a light trim at the highest setting.

Ensure new lawns (either from turf or seed) do not dry out during dry spells. Keep off them for as long as possible to allow establishment. Don't worry over a flush of weed seedlings in newly seeded turf. These will disappear once regular mowing begins.

Moss can be a problem in damp, poorly drained lawns. Spring is a good time to remedy moss problems. There are several options for dealing with moss in lawns, including raking it out of the lawn: see our advice on moss in lawns for further detail.

Remove unwanted weeds using a trowel or grubbing tool.

To encourage more wildlife into your garden consider stopping mowing part or all of your lawn in early May, the wildflowers in the lawn will grow up to flower and provide pollen, nectar and shelter for insects and other wildlife.
