Solanum Lycopersicum var. cerasiforme 'Red Alert' F1

Grow from seed in early spring in heat, one seed per tray division, or pot. Fill 9cm (3½in) pot with seed or multipurpose compost.Level and firm the compost, then water. Sow seeds on the compost surface, spacing them evenly, about 1/2" apart, (to help prevent "damping off" disease). Cover the seed with a layer of vermiculite, or sifted soil or compost. Keep at approximately 21°C (70°F), ideally in a heated propagator, When seedlings are big enough to handle, plant out in to a greenhouse - at least 16" apart - or, although less satisfactory, to a sunny windowsill

Plant tomato plants grown from seed into the greenhouse border, when they are big enough to handle, and when risk of frost has passed. For outdoor varieties, young tender plants need to be hardened off, gradually, first in a cold-frame, and then in the open, before planting into their permanent position.
