When you divide your irises because they are too thick and have stopped blooming, how far apart should you space them when you are replanting?
how to plant
I dont know what TB's are but I assume I should plant about a foot apart. Thanks so much for helping me. DG'ers are the best!
Thanks for defining TB. I have this kind as well as Louisiana and the zig zag.
18" to 24" for the bearded and at least 24", better 3' for the Louisiana.
