ussurian pear started in large plug trays

ussurian pear started in large plug trays. They can be a bit tricky to grow in trays or beds so I've had better luck in the first year as a plug. some of these are large enough to graft next spring, though most I think should grow another year in the ground. i'm growing 20:1 apples just because of rootstock availability in Canada, for zone 3 pears. basically they need to be seedlings, and basically you need to grow them yourself. I'm going to try some varied trays and small beds next spring as well, since stooling ussurian didn't produce results . some ohxf87 is possible though it's more of a zone 4 stock.
