Regularly mow lawns to keep them in shape - removing 'little and often' is the key to a good quality sward. Continue cutting lawn edges with a half-moon edging iron to ensure they are neat.

Mow pathways through areas of long grass to allow access to other areas of the garden (right).

Add grass clippings to the compost heap in thin layers (too much grass all at once is likely to be very wet and poorly aerated, resulting in smelly slime rather than compost).

Apply a high nitrogen summer lawn fertiliser if not done last month to encourage a healthy-looking lawn - always follow the manufacturer's instructions carefully, as any over-use or runoff can cause water pollution.

Move garden furniture and other objects regularly to allow grass to recover and prevent yellow patches.

Ensure new lawns (either from turf or seed) do not dry out during hot weather, as turves will shrink if allowed to dry out, and fail to knit together.


During periods of prolonged dry weather, you could help by keeping your lawn a little longer than usual, and even investing in a mulching mower. Mulching mowers shred the grass clippings very finely and then blow them into the lower layers of the turf, where they act like mulch to help the lawn retain moisture. Because the clippings are fine, the end result is not unsightly, especially later in the season when the lawn gets very dry, and the mulch helps to keep it green rather than brown.

If moss is a problem, good lawn maintenance will help to control it, see our advice on moss in lawns for further detail. Many gardeners choose to tolerate at least some moss in their lawn, as they find it helps to keep it looking green when conditions are less than ideal.

Wildflowers and flowering weeds can add wildlife value to lawns, however unwanted weeds can be removed with a trowel or grubbing tool.

Disperse dry worm casts with a hard-bristled broom.

Molehills can be a problem in lawns. Tolerate moles if possible, however should the activities of a mole be considered too disruptive there are several steps can be taken encourage them to move elsewhere.
