I want to separate some plants this fall…is this a good time?

Question by But Inside I’m Screaming: I want to separate some plants this fall…is this a good time?
I want to split and move some hostas and bearded irises. Do I need to wait for all of the foliage to die before, or can I do it now? I live in zone 4.

You can separate & move them now. You don’t have to wait for the foliage to die. For Iris, it’s best to do this early enough so they can get established before winter sets in.

If you don’t divide Iris when they get crowded…they don’t like to bloom. Also if you plant them too deep…they won’t bloom. Make sure their rhizomes have their top part exposed so they can get some sun & won’t rot. Cut the leaves in a fan shape to compensate for the lose of roots.

Hosta is tough enough to divide anytime after the plants have hardened off & are not still tender. These instructional videos on Hosta discuss dividing & transplanting Hosta in the spring or later in the fall:

Good luck!!! Hope this is helpful.
