Description
Start off in a seed tray indoors and plant out in borders. Fill a seed tray with good, free-draining, damp, seed compost. Sow seed on the surface of the compost and cover with a very fine sprinkling of dry vermiculite or finely sieved compost. Place the seed and tray in a propagator or seal inside a polythene bag and keep at around 20-25C (68-77F) until the seeds germinate. This will take about 7-14 days. Don’t exclude light as this helps germination. When the seedlings are large enough to handle, transplant them individually into 7.5cm (3") pots or multi-cell trays. Before planting out, acclimatise the plants to cooler conditions by putting them outside for a few hours a day for a few weeks. Plant out when all risk of frost has gone about 45cm (18") apart. Sow Cosmos seed from March to May at a depth of 3mm (1/8") in a good quality seed compost, and cover the seeds with a very fine sprinkling of vermiculite. Place the seed tray in a propagator at a temperature of 18-25C (64-77F) 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 7-15 days. When seedlings are large enough to handle, transplant into 7cm (3") pots and grow them on in cooler conditions until large enough to plant outdoors. When Cosmos plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over 7 to 10 days. Transplant outdoors in full sun in any moist, well-drained soil at a distance of 45cm (18") apart. Pinch out the growing tip of each stem when transplanting to encourage stems to branch and produce more Cosmos flowers.
