What Grafts Onto The HCB-1 Hybrid Pistache?

Question

I purchased the hybrid pistache rootstock and want to know if other nut trees like almond can be grafted onto it.

Answer 1

They need to be a closely related species for the grafting process to work. It is more closely related to cashews and mangos. You may want to contact your local extension agent who may be able to help you with a graft.
