Leaving Oregon for home in Florida in 2weeks. Last year I left all foliage on the plants, no mulch or covering. Had many nights below -12. Most all survived well, lost some in the pots. So do I mulch the foliage clipped plants? Or just leave them naked. Or not clip at all. Confused in Bend, Or 97707 |
I have Siberian Iris growing for years in Wisconsin. I cut them to the ground in fall after the leaves turn brown. They come back every year. |
