I posted on the Fruit & Orchard forum, but I wanted to link to it from here b/c I thought you all might know of some scion sources or have some suggestions for me. Thank you! Here is a link that might be useful: My Post

In the UK the commercial form of Mazzard rootstock used for cherry propagation is F12/1. It is resistant to bacterial canker and trees typically reach a mature height and spread of 20ft x 20ft or more.

I found the nursery in Monroe Twp I'd been looking for- where I bought these last year - Pop's. But they don't have these this year, altho they have a really nice collection of unusual annuals and perenniels. Any ideas of where I could find these plants? Not too far from central Jersey. thanks.

Adams County Nursery sometimes has some, but they havent even opened ordering for 2017 on their website yet and they were sold out of alot of things when I was on the hunt for a few supplemental trees last month.
