Summer

After the first burst of growth in spring, grass growth usually slows down. Continue to mow frequently, but don't collect the mowings. When only mowing off a little grass at a time, the mowings are unobstructive and quickly decompose, returning nutrients to the soil.

Autumn

Wormcasts become more obvious now, making mowing a slippery job and providing a seedbed for weeds. Allow time to drag a stiff brush over the lawn before mowing, to disperse the casts and knock dew off the grass. An acidic fertiliser (eg one containing iron sulphate) makes the soil less attractive to cast-forming worms.

Remove leaves regularly before they block light to the grass. Don't delay because once worms pull the tips of leaves into the ground, they can't be swept up. Use a brush, lawn rake, mechanical lawn sweep or rotary mower.
