Gladioli and Iris bulbs on the front range- winter
This may seem a little early to be asking this question, but do gladioli bulbs need to be dug up and stored during the winter around here or can they be left in the ground?
I was once told they need to be dug up, which we did last year, but I am looking for a second opinion in case it might not be necessary.
Also, iris bulbs - the dutch nonrhizome type that look like onions. Does any one know if I'll need to remove them from the ground in the fall?
