Manchurian apricots, sprouting in the fridge at 120 days stratifying

Manchurian apricots, sprouting in the fridge at 120 days stratifying so time to pot up. they don't need the shells removed, which just fall apart when ready. excited because these have good genetics. from a local zone 3 apricot orchard where a named cultivar was selected. time to plant our own apricot grove. and use for rootstocks.
