This month sow the wildflowers primrose and cowslip in a cold frame.

Sweet peas can be sown in a cold frame or unheated greenhouse to over-winter. The young plants can be planted out in March/April to obtain early blooms.

Once summer bedding plants have been removed from your borders, plant spring flowering plants such as bellis (daisy), pansy, polyanthus, primrose and wallflowers along with spring flowering bulbs. When rose blooms have faded a last deadheading of roses can be done, and taller stems may be slightly shortened so that movement from wind can be reduced.
