How to Propagate Gladioli?
Gladioli is commonly propagated through corms, which are a type of underground storage organ. Key factors for successful propagation include well-draining soil, warm temperatures, and full sun exposure. Special considerations include waiting for the corms to form and harden off before planting. The general difficulty level is moderate, with the main challenge being the proper separation and treatment of corms for disease prevention. To propagate, follow these steps: 1) In late summer or fall, dig up mature corms and remove the new cormlets, 2) Allow them to cure for a few days in a warm, dry location, 3) Store the corms and cormlets in a cool, dry place over winter, 4) Plant the corms in spring after the last frost, about 3-4 inches deep in soil with good drainage, and water thoroughly. This ensures a higher likelihood of successful propagation for gladioli.
