The Q&A Archives: Gladiolus

Question: I have gladiolus that bloomed in spring and were so tall they kept falling over. I want to dig the bulbs and put them in an area where I can more easily handle them but some of the leaves refuse to die back and this is November 4th. It may or may not frost before spring. Would it really harm them if I cut green leaves off now?

Answer: Leaves provide food for the corms, so it's understandable that you're reluctant to cut the foliage off of your gladiolus. But, commercial growers cut the leaves off the corms while they're still green, so it probably won't hurt yours to do the same. You can dig the glads, cut off the foliage just above the corms, and replant immediately, or allow the corms to dry in a shaded, ventilated area for about three weeks. Then store them at 40F - 50F until spring when it's time to replant them.
