Hi friends, I'm living in the northern of Vietnam. Now I'm growing some A.P Matsumurae and Dissectum, and found they reply good in my garden. So I want to have more cultivars. What I'm wondering is: For A.Shirasawanum Aureum, can I use Aureum scion to graft on to rootstock(A.Palmatum green)? Or do I need to use Aureum scion to graft on rootstock:A.Shirasawanum? Many thanks in advance!
