Do I cut back the blades of blackberry lily plants in the fall, as I do Iris, or leave them? I have pulled bad leaves already. Thanks.
Cutting Back Blades of Blackberry Lily

They do not need to be cut back, nor do the irises. Allow the foliage to die back naturally, as the plants need this for producing enough energy to go into next year's blooms. You can, however, cut back any old blooms and stems down to the base.
