CARE
Gladiolas are winter hardy in zones 7-10. In colder zones they can be grown as annuals or the corms may be dug up in the fall and stored indoors for replanting the next spring.
Plant your gladiolus bulbs from February to June. Grow in frost-free conditions or plant straight outside after the risk of frost has passed
Grow in borders or containers in full sun or partial shade
Plant the bulbs 10-15cm deep
Space the bulbs about 10-15cm apart
Plant with the pointed side facing upwards
Water well after planting and keep hydrated while in growth
