Two years ago, i cut raspberry canes from an escaped alley dweller and managed to root one. I've had to move the plant twice to completely different yards, and though the cane grew and sent out other branches/canes, it hasn't bloomed at all. The parent plants are fruiting like crazy. Do raspberries need a couple of years to establish? Am i doing something wrong? The growth is vigorous and strong and i used sheep manure, and the plants are in full sun with moderate amounts of watering, unless the weather warrants more, but green leaves and tall canes are not why i'm growing it! I'm in Calgary's Zone 3.
