Growing Information and Gladiolus Life Cycle

Gladiolus life cycle begins when the corm is planted in spring after the danger of frost has passed. Roots emerge first, followed by a sword-like shoot that eventually sends up a flower stalk. Blooms open from the base upward over several weeks, creating a prolonged show of color. In USDA zones 3–6, corms should be lifted and stored in a cool, dry place after foliage has died back. In warmer climates, leave them in the ground to return each year.

Plant corms 5 inches deep and space them 4–5 inches apart in full sun. Water regularly, especially during dry spells, and use mulch to retain soil moisture and suppress weeds. For expert planting and care tips, visit our guide on Growing Summer Blooming Flowers: Gladiolus.
