I read the heck out of a thread yesterday (sorry I have not read the above links) and basically peach on apricot = “many will not do well. some ok”
Asian / European plum grafting compatibility
If you were to bridge pluot first then peach on pluot, you should be fine.
Here are my notes and a chart from this thread:
(See Chart)
I’ve read this thread now twice and compiled notes:
EDIT: European to Asian plum = no
Asian to European is not always compatible. In fact in most cases is not. Don’t even mess with it. (crfg publication) The majority of members report incompatibility. EDIT: According to the chard many will work.
Japanese plum to Japanese plum or rootstocks: St Julien, Citation, Krymsk 1, Krymsk 86
Peach accepts European plums (chart says); pluots do well according to Lizzy; Asian plums do well according to Lizzy but member Lizzy however lost many E.plums on peach. Figure that one out.
Apricots accept pluots very well. EDIT: Japanese plums (Some see chart) / European (Most not compatible)
Raintree Nursery puts all their multi-plum grafts onto peach root.
Old Asian plum trees may have better acceptance to European plums because they are not as vigorous as younger trees. There within lies the possible compatibility when grafting European plums to Asian plums.
