One more mow to go?
Keep the lawn clear of fallen leaves which block out light and repair damaged edges and any patches. If you are planning to sow a new lawn in spring you can start deep digging, raking and tramping down the soil in preparation.
Try not to walk on the lawn when it’s frosty – it can damage the grass. Continue brushing out worm casts and check for any problem areas to note you may need to deal with them: waterlogging, algae where there is poor drainage or excessive shade which needs cutting back, Fusarium patch or snow mould where the grass may have been overfed. Add them to your checklist to take remedial action and follow your lawn maintenance regime come spring.
