How Does a Gladiolus Reproduce?

Corms

• Corms look similar to bulbs but have some important differences. Each year, the mother corm shrivels as its carbohydrates and nutrients are expended, and a new corm forms in its place. The cormels that develop at the base of the corm grow into mature corms over a period of a few years.

Dividing Corms

• Divide corms that have more than one bud at the top. At planting time, use a sharp knife to divide the bulb as equally as possible. Each half should have one bud.

Cormels

• Remove cormels that are dime-size or larger from the base of the corm, Store them over winter in an open box or jar. Before replanting in spring, soak them in water overnight. Plant them 1 to 2 inches deep and keep the soil moist until the plants emerge. It takes two to three years for cormels to produce flowers.
