Apricots on Plum Rootstocks
I've read that grafts between apricots and Myrobalan are weak and often result in damage at the graft or delayed incompatibility. Apricot seedling rootstocks are recommended for best results. Peach seedlings are somewhere in between. Myrobalan is only recommended for sites where apricot and peach rootstocks cannot tolerate the soil. However, shorter life expectancy is to be expected.
Any opinions on this? Does delayed Myrobalan incompatibility contribute to sudden unexpected death of apricots after a few vigorous years? What about Marianna 2624?
