Hello, I am new to fruit trees and newer to grafting. I am curious if it is possible to graft onto a graft? I have a Wurtz Avocado tree in my yard that is about a year old. I want to graft onto the main leader a malama variety, then after a few months of growth, graft onto the malama part a sharwill scion. maybe even graft onto that one in a few months a Murashige Avocado variety.
Is this possible or does it not work like that? my intent is to make a avocado tree that fruits most of the year.
and on a side note, will the wurtz, which is smaller than most trees, keep the overall tree small even though I've grafted larger more vigorous varieties? Please let me know! Mahalo.
