Will Gladiolus bulbs die if left in the ground

Question

If I do not dig up the gladiolus bulbs each year, will they die, rot or not bloom again?

Answer 1

My mother, in North West Pa, never dug her glads, and they would flower, but they'd get fewer and smaller every year, until she had to get a new bunch. Most gardeners agree that you have better luck with them if you dig and store them.
