Grafting Paw Paw
I have recently ordered a small Shenandoah and a Susquehanna paw paw seedling for delivery in October. In northern VA is it advisable to immediately plant them in their designated lanscaping spots and allow them to overwinter there or to pot them and keep them in a cold garage and put them out in the spring?
I eventually want to graft a scion from each species onto the other to help with polination. What type of graft should I use?
