How to Take Care of Gladiola Bulbs During Winter
- 1). Dig up the gladiolus after the foliage dies back. Dig a trench 6 inches out from the base of the plant, circling the plant. Make the trench 3 to 4 inches deep. Slide your trowel under the corm and lift it from the garden bed.
- 2). Brush the soil from the gladiolus corms. Break off any small corms growing from the main one. You can save these for replanting, though they may not bloom for two or three years.
- 3). Cut the dead foliage stems off the corms with a sharp knife. Leave no more than ½ inch of foliage attached.
- 4). Dry the corms for 14 to 21 days in a dry, shady area where temperatures remain between 60 and 70 degrees Fahrenheit. Brush the remaining soil from the corms after they finish drying.
- 5). Line a shallow box with dry peat moss. Bury the corms inside the peat moss. Store the boxes in a dry, 40 degree Fahrenheit location until you replant them in spring.
