Quarantine scions?

Hello folks! I have a handful of extra apple rootstocks and I would like to get some scions from old apples trees nearby to graft.

Should I keep the trees grafted from the old wood separated from the trees I grafted from nursery grown scionwood? Not sure if there is risk of disease transfer.


If the older trees look healthy, there’s not much risk. If there is something specific that concerns you, post a pic showing what you see so other members can help evaluate.
