Straighten lawn edges using a half-moon turf iron and a board, or use sand to mark out a curve, which can then be cut out with the iron. At the same time, create a 7.5cm (3in) ‘gutter’ around the lawn to prevent grass spreading into your borders.
See our guide to spring/summer lawn care.
Worm casts are a sign of healthy soil, but if you don’t like them on your lawn, brush them off with a hard broom once they dry out.
Re-seed bare patches at the end of the month in mild regions – but delay if the weather is cold as the seeds won’t germinate.
Molehills can be a problem if you want a neat, flat lawn, and spring can be an active time for moles, as they tunnel in search of food. Tolerate them if possible, but if you want to encourage them to move elsewhere, see our guide to moles.
