Can anyone help me figure out why my Fallgold raspberries won't flower and fruit? I live in Zone 7, at 3,500 feet. Our summers tend to be rather hot and dry, so the FGs are in a lightly shaded bed. They multiply like crazy! I planed one, the next summer it was 7, 25, now 60. It would be nice if they'd fruit though. NorCal Pat
