Does anybody know if European Hazels (Corylus avellana) can be successfully grafted onto the native PNW beaked hazels (Corylus cornuta)?
I have a bunch of beaked hazels that I'm probably going to remove (yes I know they produce edible nuts, but they are few and far between and rather small), but was thinking of trying out grafting the Eur. hazels onto those already existing root systems.

You can graft any Corylus to any other Corylus and the graft, if done correctly, will take, no worries there since you are staying within the same family.

If you wanted to, you could leave one or two branches on the Corylus cornuta root stock just for fun or so you have two species of nut available.
