How to get a cutting of root stock to root
I went to a grafting class and we learned how to graft apple trees. They started with root stock MM111 and clipped the top to make space for the cleft graft--the instructor asked if we wanted to take the top portion of the root stock and try to get it to root. So I did.
But, I don't know how to have a cutting of root stock root?
Can I put it in a plastic bag in sunny spot inside with some moist sphagnum moss?
