Vegetables

Prepare a deep trench, for Runner beans You can fill the trench with compost (well rotted) or a good rotted manure. Then in late spring cover with soil and sow your beans on top.
Seed potatoes should be stored in trays, in a light, cool, frost-free place to chit ready for planting in March or April. Broad Bean Sowings can still be made
Sowings of onion should be made in the greenhouse, harden off the plants in March prior to planting outdoors in April.

Flowers

Sowings can be made of antirrhinum, begonia, dianthus, geranium, gloxinia, lobelia, salpiglossis, statice, sweet pea and verbena. Some perennial plants such as anemone, auricula, aquilegia, hollyhock and kniphofia can also be sown at this time. Sweet peas that have been raised from autumn sowings can be encouraged to form sideshoots by pinching out the seedling tips. 

Cut down flowering perennials to ground level. Any newly planted perennials or winter bedding that have been lifted by frost should be firmed back in.

When leaf shoots begin to show on crocuses, remove the pots from the beds where they had been placed, clean the pots of any old compost and place them in a cold greenhouse for the flowers to develop.  

Bare-rooted roses can continue to be planted. To avoid disease refrain from planting new roses where old ones have been removed from. However, the exception to this is if the soil has been replaced and conditioned.
