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.
Do You Have to Dig Up Gladiolus?

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.
