Do you have to dig up gladiolus?

Question

I planted gladiolus years ago. I have never dug them up and they come back every year. This year there is an area I want to change and I will need to dig the gladiolus up. I want to make sure I do it right. But in reading the information, it states to dig up gladiolus every year. I just wanted to know if this was true.

Answer 1

These plants only need to be dug up in colder regions. In your area, the bulbs do not need to be dug up and stored for winter; however, in zones 6 to 7, they thrive better if the bulbs are protected by a thick mulch throughout the winter. After moving them where you want, simply leave them be and they will continue to reproduce each year, dividing them once they become overcrowded.
