Tuberous begonias that have hibernated through the winter need prodding into action now. Tip them from their pots, clean off old stems and then settle them into a tray of moist compost to sprout again, concave side uppermost. A heated propagator will speed up the sprouting. When new leaves have appeared, plant the tubers in separate pots and grow them on at a temperature of around 50F.
Continue to sow seeds of annuals such as sweet peas, tobacco flowers and petunias to set out later in the season. I have just sown seed of a perennial aquilegia called Double Pleat (Thompson & Morgan pounds 1.89) with frilly double flowers of purple and white. Ideally seed should be sown fresh in late summer, but this does not suit seed companies. Germination is better if you put the seed, sown in a pot of compost and covered with clingfilm, into the fridge for a couple of weeks, before bringing it out in the warm. If the seed sprouts while it is still in the fridge, bring the pot out and let the seedlings grow on in a warmer place.Reuse content
