Winter repair and maintenance
Avoid walking on lawns on frosty mornings. It can damage the grass and often leads to brown footprint-shaped marks.
Continue to remove fallen leaves from lawns before they block out light and moisture to the grass.
Grass will continue to grow in temperatures above 5°C (41°F), so if the weather remains mild it may be necessary to use the mower to keep the lawn in trim. Ensure the cut is 3-5mm higher than during the summer to prevent turf stress. On average, this means a cutting height of around 2-4cm (1-1.5in) for a utility lawn.
Repair damaged lawn edges or patches with turves cut from other areas of the garden. Re-cut all lawn edges to crisp up the appearance of the garden, and save work next season.
Too much water
Watch your lawn for signs of waterlogging, as the weather gets wetter. You may be able to remedy this with some maintenance - either now, next spring, or the following autumn.
If your lawn suffers dieback from treading during the wet, muddy season, then you may wish to lay stepping-stones through it to allow easy access across it without causing damage. Stones can be laid at a low enough level to avoid interference with mowing.
Fusarium patch (snow mould) may be a problem in wet weather, particularly on overfed and lush lawns that have been left a bit too long.
Algae can be a problem on lawns where there is poor drainage, excessive shade, or under the drip-line of trees.
