Sow seeds in January to may on the surface of a good, free-draining, damp, seed compost and place at a temperature of at 18-29C (65-85F). Lightly cover the seed with vermiculite. Place in a propagator or seal container inside a polythene bag until after germination which usually takes 20-25 days. Do not exclude light, as this helps germination.Transplant seedlings when large enough to handle into trays or 7.5cm (3in) pots. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost. Space the plants about 1 foot apart. If you're planting petunias in containers, use a soil-less mix.

Care

• Petunias are tolerant of heat so you don't have to water them regularly. A thorough watering once a week should be sufficient (unless there are prolonged periods of drought in your area). The spreading types and those in containers require more frequent watering though.
• Fertilize your plants monthly to ensure good growth. Double-flowered cultivars like a biweekly dose of fertilizer.
• Remove faded/dead flowers to prolong blooming.

 The seeds are supplied in a special self seal airtight clear seed bag.
