How to root cuttings from butterfly Bush?
What is the best way to root cutting from Butterfly Bush? In the past I have just taken a branch and laid it on the ground....pinned it down with a small piece of wire ...covered with soil and let it stay attached to the main plant until it formed roots of its own. I have several butterfly bushes and want to start some more for trades and to give to a friend for her garden. What are the best size cuttings? both length and diameter of the stem? any help will be greatly appreciated. Also I am wondering about mock orange, and purple plum can these be started from cuttings? Thanks
