you can also take bark from an oak tree and boil it and then dip your cuttings in this and it works well also
I have never heard of this we have a lot of oak tree's will have to try it.
I borrowed a few tiny limb's off a weeping willow tree.Dipped them in rutone and stuck them in potting soil .
I looked at them today they have tiny green leave's coming out.
I have considered that too, Jade. But I justify the outlay by considering it a recreational expense. I also justify it by not playing golf. LOL
Jade, at our last house, we didn't have those restrictions, but I really didn't have the room for anything big, so I put in a coldframe by the back porch. It was really surprising how many plants I could put in something 3' x 4'. I had enough for myself and enough to give away quite a dew to friends.
