The Q&A Archives: Gladiolus

Question: Several years ago I planted a variety of gladiola bulbs. Our climate allows them to stay in the ground all winter. Each year we get less and less of a variety until now they are all pink. Why did this happen? What can I do to prevent it?

Answer: It sounds as though some of the hybrid corms died off and the more vigorous corms - in this case pink - took over the bed. You'd be doing your glads a favor to dig the corms when the leaves begin to yellow and store them in a cool, dark place until spring. Then plant them back in the garden. You'll lose fewer corms this way, and will have nice healthy plants that will present you with new baby corms, to increase your stock.
