1 Packet (75 Zinnia Seeds) (TT06818)
Direct sow zinnia seeds outdoors where they are to grow from April to May once the soil has warmed. Choose a position in full sun on moist, well drained soil which has been raked to a fine tilth. Sow seeds thinly, at a depth of 3mm (1/8") in drills spaced 30cm (12") apart. Water the ground regularly, especially during dry periods. Germination usually takes 7-14 days. When zinnia seedlings are large enough to handle, thin them out to 23cm (9") apart.
Alternatively, sow indoors from March to April at a temperature of 15-25C (59-77F). After sowing, keep the surface of the compost moist but not waterlogged and do not exclude light as this helps germination. When seedlings are large enough to handle, transplant and grow them on in cooler conditions. When zinnia plants are well grown and all risk of frost has passed, gradually acclimatise them to outdoor conditions for 10-15 days before planting outdoors.
