After Season Care For Gladiolus Bulbs
Standard Gladiolus: In zones 8-10, you can leave Gladiolus bulbs in the ground for an easy-to-grow flower that returns each season; your Gladiolus bulbs will rest for several months before starting their cycle again. If you are in zones 3-7, you can either treat your Gladiolus as an annual, replanting new corms in the following spring, or you can dig the corms to store for winter (see tips below).
Hardy Gladiolus: In zones 5-8, you can leave Hardy Gladiolus bulbs in the ground for an easy-to-grow flower that returns each season; your Gladiolus bulbs will rest for several months before starting their cycle again.
