What to Look for When Purchasing
Ethylene has been shown to cause abortion of unopen florets. Ask if your supplier has treated the product with an ethylene action inhibitor. Avoid stems with brown or shriveled florets. Avoid stems in which foliage exhibits tip burn. Choose spikes that have a few open florets. Flowers should have 1-5 stems showing color.
Miniature cultivars available. Gladiolus make excellent line flowers and can provide a lot of height for larger, showy arrangements. In any arrangement, associate with other flowers that have similar vase life characteristics.
Pest & Disease Information
Gladiolus are resilient to diseases post-harvest, except for when exposed to ethylene.
Flower fade/translucency due to ethylene and/or high temperatures. Remaining florets do not open due to early harvest, stored too long, extreme temperatures, and/or low humidity. Petal and foliage burning due to excessive fluoride. Avoid fluoridated water. Gladiolus stem ends are prone to developing a biofilm formation when in water due to bacterial growth. Sensitive to leaf yellowing. Use bulb flower food. Store upright if possible as Gladiolus tend to bend and deform.
