All About GladiolusGladiolus makes its appearance in mid to late summer and lasts up until the first frost. Because the flower stalks are relatively fragile and usually must be staked, their most popular use is as a cut flower. Each stalk produces several blossoms, and may reach a height of 2 to 4 feet. Planting several together in a group not only gives them some protection, but with the numerous available color combinations, will provide a brilliant display.
Growing GladiolusWhen you are able to work the ground in the spring, choose a sunny location with soil that drains well. Gladiolus is grown from corms, which resemble bulbs. Depending on the size of the corm, set it into the ground at a depth of 4-6 inches with the pointed end facing up. Space additional corms about 6 inches apart. Water well. Many people plant a few new corms every week or so to ensure a steady supply of new flowers.
Gladioulus corms will not survive cold winters, and need to be dug up in the fall. Cut the foliage away close to the corm and discard. Rinse them off and lay them out to dry where they will be protected from the cold. Once they are dry, you can put them in a paper bag or box and store them inside for the winter.
