I have two cornus mas, but I think they are too far apart to pollinate.
I've decided that rather than move the smaller one, I will buy a new
one this fall. (My soil is rocky, and if the roots have established
much, it will be very hard to move the tree.) I will put it near the
one that is doing better. There's more sun on that side.
Any advice on good cultivars, and/or good people to buy from? I prefer
to buy from east of the rockies, partly because the shipping is less
stressful for the plants, and partly because I'm afraid of sudden oak
death. (Although I suppose we will all be seeing that all too soon.)
Also, it's always easier to buy from the same climate or north, rather
than from the south. A southern plant may have broken dormancy in the
spring before I can get it in the ground, and may not have hardened off
in the fall.
