|I live in the Phoenix Metro area and have an Iris bed I moved to it's new location last Fall. We are now hitting 100 teens and they are showing signs of stress. I don't think it's a water problem. Should I cut back the leaves as if I were moving them to lessen their stress? If not, is there any time that's appropriate to cut them back?

|Wait until the leaves dry and and die down, then cut them off. As long as they are green they're collecting and transporting carbohydrates to the rhizomes. I know they look pathetic but soon they will die down and you can remove them from the beds.
