Speedster,
I agree I’ve found sour cherries such as Montmorency very easy to graft but sweet cherries are something different. Apricots are a real pain like peaches!
@IowaJer,
ER should be easy to graft but I’m curious how big you want your tree to get? I would hold off until Jan or Feb to harvest scion wood. I’m one state away and it’s usually cold then. You might grab a little wood now in case February turns into shorts weather like last year. You want the wood totally dormant which for me means a -10 F day is great. My trees still have leaves hanging on them. I will get my scions in early Feb… You might like this sweet cherry grafting thread Sweet cherry grafts. Sour cherries are much easier but the concept is similar.
