Choosing Grafting Understock
Where can I find out what types of understock are compatible with which scion wood? What understock do you use if you want to graft a Hydrangea paniculata on a standard? What about Syringa meyeri on a standard? These are just a few of the many examples I am looking for answers to. I have heard of some strange combinations that I would never think of, like grafting Chamaecyparis pisifera on Thuja occidentalis. Is there an "understock" book that tells all of this info? Many thanks!
