Still growing? Keep mowing.
Depending on the weather in your area you may still need to mow but set your mower or cutting deck to winter height (which you would have done in October). The height depends on your type of grass. For ornamental grass a winter cut of around 18mm, leisure, 25mm and utility 25mm+ are often the recommended heights but as a rule of thumb most household lawns will benefit from final cuts at about 4cm (1.5”) to help protect the grass through the winter.
If the temperature is still above 5ºC (41ºF) the grass is likely to still be growing. There’s a temptation to use up feeds and fertilisers during the autumn clear up but don’t feed the grass unless you’re giving it potassium and phosphorous to help it combat stress in the months ahead. By giving it more nitrogen, you’ll be making it vulnerable to disease.
New turf can still be laid if you’ve prepared the ground and it’s not too wet or frozen. Clearing up leaves from the lawn is essential and made easier on the large lawn if you have a garden tractor with a sweeper/collector. You can still scarify and aerate, if the ground remains relatively dry, followed by applying a top dressing. Similarly, brush out worm casts on dry days. Trim edges and keep an eye out for any areas of disease on the lawn, such as fairy rings, which may need treating.
