Sow vegetable seeds
Sow seeds in modules/pots in an unheated greenhouse: broad beans, leeks, lettuce, rocket, coriander, peas and Swiss chard. Sow sweet peppers, chillies, tomatoes, cucumbers, aubergines, celery and globe artichokes in a propagator.
Early strawberry crop
Plant strawberry runners in hanging baskets or pots to grow in the greenhouse for an early summer crop.
Pot up Agapanthus
Repot established Agapanthus into slightly larger containers – but they do like to be rootbound.
Top-dress acid-loving fruit
Mulch raspberries, blueberries, cranberries and lingonberries with well-rotted farmyard manure (not mushroom compost as it is too alkaline).
Prepare runner bean trenches
Start preparing runner bean supports and trenches for sowing (in May) or planting out (in June).
