Can You Trim Back Morning Glories Before Transplanting Outdoors?

Question

I started my morning glories indoors & have them climbing on a wire but they are growing so high & it will be weeks here in Upper Michigan before they can be put outside. Can I cut them back or will that prevent them from regrowing or shock them, or stunt their growth?

Answer 1

You can cut them back. It will encourage branching.
