More tips from Pete Anderson - March 2010
Around the middle of the month, plant first early potatoes, second earlies being planted at the end of the month. The seed bed may be sown around the middle of the month if conditions permit. This includes cabbage, sprouts, broccoli, leeks. Sow in their final growing positions peas, broad beans, onions, radish, parsley, parsnips, spinach, swedes, turnips, beetroots, carrots. Carrots will need protecting from carrot root fly by either a tall barrier around them, or by covering with a mesh tunnel. Both need leaving in position until autumn. In a greenhouse, sow celery and African marigolds for companion planting with brassicas to reduce whitefly in summer. Cut down autumn-fruiting raspberries when new growth appears.
