Mine are grown in pots too. About 4 years old, maybe 5. Not producing a lot and they're not good unless very ripe. Noticed the birds ate the ones on top so I sorta panicked and picked all the rest I could find. None of those were sweet or tasty at all. I'm giving them one more year and letting the fruit ripen longer. If they're still only providing a handful of fruit from the 6 large plants, I'll probably sell some off to make room for more productive, tasty edibles. Really, IME, the only thing "honeyberries" have going for them, at least my varieties, is they are the first fruit of the season.
