Should Gladiolus Bulbs Be Dug up in the Fall?

In U.S. Department of Agriculture hardiness zones 7 and 8, dig up gladiolus bulbs after the foliage has died and before the ground freezes. Gladiolus bulbs are food-storage structures called corms.

  1. Dig up the plant with a spade, being careful not to damage or bruise the corms. Cut the stem back to 1 inch. Discard any damaged corms. Remove the old corms from underneath the new corms.
  2. Shake off the soil and allow the corms to dry in the sun for 2 days. Cure in a well-ventilated location at 80 to 85 degrees for two weeks.
  3. Store the corms in trays with screened bottoms, onion bags, or paper boxes and bags. The environment should be dry and a constant 35 to 45 degrees. Do not allow them to freeze.
