Lawns:
If weather conditions are still mild and the grass is still growing give it a light trim; also continue to remove any fallen leaves that have blown onto the lawn. A handy piece of equipment to have for removing leaves (plus other garden debris) not only from the lawn but paths, between plants, etc is the Blower/Vacuum. A hollow-tined aerator can be used for spiking lawns and grit or sand can be brushed into the holes for improved drainage. Keep off the lawn if soil conditions are wet or frosty.
Borders:
Perennial plants that are past their best should be cut right down, remembering to clear away all remains and add them to the compost heap.
Bulbs:
Planting of spring bulbs should be completed as early in the month as possible
