Other greenhouse vegetables

Early and late season supplies of carrots can be had from the greenhouse, frame or low tunnel. Sow ‘Early Nantes’ or ‘Amsterdam Forcing’ in December or January for supplies in late May and June. A late sowing of the same varieties in August gives a December crop.

 

Early carrots from a cold frame

 

White turnips, broccoli, radish, scallions and parsley can be grown under protection too. Sowing can start in January in a cold greenhouse or frame, December in a cool greenhouse. Delay sowing until early February under low tunnels but put up the tunnels about three weeks before sowing.

Florence fennel and chinese cabbage are two crops that are difficult to get right outdoors – they both have a tendency to bolt if the weather is not warm and moist. Sow florence fennel in late March and chinese cabbage in May. Keep both well-watered to prevent bolting.

Early and late potatoes can be produced under protection. Planted in December or January they will be ready in May.
