They are frost to half hardy and will need a sunny and fertile, well drained site. You will need to plant the corms 10-15cm deep and the same distance apart in spring, water well in summer and support the tall cultivars with canes. Cormlets, removed after lifting should be stored in frost-free conditions and then be planted out 5cms deep in spring; lift in winter as for mature corms. They will flower in 1-2 years.
You can propagate by seeds or by removal of young cormlets. The seeds should be sown in early spring in a cool greenhouse. Seed sown in early spring in a cool greenhouse will take 2-3 years to flower and may not breed true to type.

Gladiolus scab causes blotches on leaves. Gladiolus yellows causes yellowing stripes then death of leaves. Affected corms should be destroyed and healthy corms should be planted in a new site each year.
