Cultivate and prepare seedbeds, covering them with clear polythene or fleece to warm up the soil before sowing.

Chit early and maincrop potatoes. If mild earlies are planted out in the second half of the month. If colder it is better to wait until April.

Plant shallots, garlic and onion sets. Plant Jerusalem artichoke tubers.

Plant asparagus crowns. A deep, friable, well-drained soil with plenty of organic matter incorporated is ideal.

Many vegetable crops can be sown this month, especially in mild areas with light soil, including: broad beans, carrots, parsnips, beetroot, bulb onions, lettuces, radish, peas, spinach, summer cabbage, salad leaves, leeks, Swiss chard, kohl rabi, turnip and summer cauliflower. Be guided by the weather, and sow only if conditions are suitable (as per guidance on the seed packets).

Fleece and polythene can be used to protect early outdoor sowings. Many vegetables can bolt if sown outside too early without protection (beetroot being an example). A greenhouse or conservatory is useful in all but the very mildest areas with the lightest soils, to start seeds off - hardening off and transplanting the young plants into the vegetable garden later in the spring.

Sweet peppers, tomatoes, cucumbers, aubergines, celery, salads and globe artichokes can all be sown in a frost-free greenhouse. Artichokes and celery can be transplanted outside later in the spring. Tomatoes can either remain in the greenhouse or be grown outside from early summer onwards. Peppers, cucumbers and aubergines do best kept under cover. Salad crops vary - it is best to check the temperature requirements on the seed packets.

Feed spring cabbages that have been standing all winter. Use high nitrogen feeds such as Growmore or pelleted poultry manure.

Continue to force chicory and seakale. Dig up selected chicory roots, pot them up, and position them in a dark warm place (10-13°C/50-55°F), with an upturned light-proof pot over them. The tasty chicons will appear in three to six weeks. Seakale is best forced outside at seasonal temperatures, with an upturned pot or cardboard box/tube over the top to exclude the light.

Put supports in place for peas.

Continue to harvest Jerusalem artichokes, parsnips, spring onions, leeks, winter salads, spring cauliflower and cabbage, Brussels sprouts, chicory, rhubarb, kale and sprouting broccoli.

When spring cabbages are ready to harvest, cut them off the stem and make a cross in the top of the cut stem. Sometimes mini-cabbages, or ‘spring greens’ will grow from the cut stems.

Feed crops which have been left sitting over winter (e.g. lettuces and brassicas). A balanced fertiliser such as Growmore or blood, fish and bone
