Hi all! I live in NE Ohio zone 5b. I am new to irises. I just planted 8 mini tall bearded irises in my raised bed. The bed is well drained (about a foot high), good loamy soil.
My question is... Since I live in an area that gets very cold down to about 20's, 10's and maybe even sometimes singe digits, and plenty of snowfall, do I mulch the irises? I don't want them to be subjected to heaving of the ground in the late fall, winter, or early spring. I have heard that mulching iris is bad. Do I just leave the "necks" or rhizomes sticking out of the ground all winter?
one who needs an "Irises for Dummies" book lol
