Re: [nafex] Apple roostocks for Display Garden
If you're looking to make this a comprehensive test, Kim, there are
several newer rootstock candidates that merit inclusion:
We have seen little difference in tree size among M.27, P.22 and Bud.
491. M.27 and P.16 are definitely less winter hardy than M.9, but that
isn't exactly your problem at Mt. Vernon. Bud.491 is very brittle, but
once established is very productive. P.22 tends to have one-sided root
system, mostly coarse roots. Unbudded P.22 is quite late to break bud
in the spring; still don't know what that implies for the tree in the
I can't recall any fire blight reports from your area. If that is a
factor, though, then do remember that all except the Geneva stocks are
quite susceptible, and G.11 is only moderately resistant.
