Can you cut the foliage of your Siberian Iris now that they have stopped blooming?

Yes, you can cut back the foliage of your Siberian Iris after they have finished blooming. It's best to wait until late summer or early fall, allowing the leaves to photosynthesize and store energy for next year's growth. When cutting, trim the leaves down to about 2-3 inches above the ground to promote healthy regrowth. Always ensure that the tools used are clean to prevent any potential disease transmission.
