Sow petunias from February to April on the surface of a good seed compost and gently firm down. Lightly cover the seed with a fine sprinkling of vermiculite. Place the seed tray in a propagator at a temperature of 21-25C (70-77F) or seal it inside a polythene bag. Keep the soil damp but not wet. Do not exclude light as this aids germination which usually takes 10-21 days.
When petunia seedlings are large enough to handle, transplant and grow them on in cooler conditions until large enough to plant outdoors. When petunia plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over 7 to 10 days. Transplant into well drained soil at a distance of 30cm (12") apart or grow in containers in full sun.
