Regular mowing is now the main task in looking after the lawn. Leave the grass clippings to wither and then put them around trees for mulching. Or compost them in a thermal compost bin. They should be slightly wilted for this too. Mix two parts of grass clippings with one part of dry shredded woody material from trees, bark mulch, dry leaves or wood shavings from untreated wood. Ideally, mix in a compost accelerator and after about 12 weeks you will have top quality compost mulch.
