Cleome seeds grown outdoors should be sowed on the surface in a partially shaded or sunny area of the garden. They can grow in most soils that have a pH of 6 to 7. When planning on growing spider flower seedlings indoors first then the process should be started about one and a half months before you plan to put them out.
Germination takes about two weeks, but first seeds should be imbibed by placing the seeds (within soil) in a black bag, then placing in the fridge for two weeks. Seeds should then be sown out at a temperature of 21 to 24 Centigrade. Seedlings of Cleome should be planted out with a spacing of about 50 to 60 cm after the last frost of spring.
Plants of the Cleome genus are easy to look after. They should be fertilized and watered whilst growing. Remove seed pods before they have chance to shatter.
