Your tricking me into more trees. I see frostbite is a parent to many varieties in the minesotta program.
Any info on that swamp crab? How well it holds into the season ,early frost tolerance, any signs of disease. We got alot of beavers up at camp, but can find some small brook edges that it might be left alone.
Debating a 2nd tree order for some anty, B118, and m111 rootstocks. What I read about the siberian crab is all over the place. Tree size between standard to semidwarf and some have compatibility issues and some say no.
