Sowing annuals

Most half-hardy (or tender) annuals may be sown now ; if you have a greenhouse or conservatory in which to keep them. Sown too early, and the plant become leggy in their search for light, making them grow into poor specimens, and no good for planting out at the appropriate time (after the frosts in late May or early June). You can sow marigolds, ageratum, stocks, tobacco plants and masses of others ; see what's on the seed racks at the garden centre!
