Beware moving this in your nursery, if you don't
want to spend your time pulling roots.
Prunus virginiana has the unfortunate habit of
spreading wildly from the root. It can send numerous underground shoots
many feet. When you graft something on this type of prunus, it soon finds itself
tighly surrounded by bushes of choke cherries.
Prunus pennsylvanica is even worse. The later is
good for prunus rootstock but it's life is short and it is easily broken so it
is usually recommended that you bury the graft union underground so your variety
will make it's own root. Meanwhile, it will send roots many tens of feet in all
directions. The roots are bigger than prunus virginiana and far more difficult
to pull. You need picks and axes.
Both plants seems to prefer sandy
soils.
On the other hand, prunus nigra, the wild plum that
you find on roadsides, likes clay and has more contained growth
habits.

Kevin, just found the website..... <http://www.agt.net/public/pchenier/thesis/fruit.html> It
mentions using prunus nigra "Canada plum". I haven't encountered
it, have you? It recommends prunus virginiana for super hardy
rootstock....anyone out there use it? I've got a forest floor covered with
seeedlings and think to move a bunch into nursery bed area for future
grafting of plum and or evans cherry. I would guess it has dwarfing
characteristics. Anyone experimented with it?
Heres another good
site for folks like me seeing photos of just what "green tip" or "popcorn"
or "silver tip" mean, from Mich. State U.
