Why won’t my Fallgold raspberries flower and fruit?
Hi, I live in zone 7A, in the Intermountain west. My property is at 4,000ft. I have approximately 60 Fallgold raspberry plants that are otherwise happy and healthy. Every year they multiply, their soil is rich, they get ample moisture. The only problem I can see is that they're in a somewhat shady area, and so they only get about 3 hours of direct, morning sunlight. My berries have never blossomed, so obviously they've never set fruit. Other than more sunlight, I can't think of what to give them to help them flower. Any suggestions would be gratefully accepted.

You can try applying potassium phosphate, but the lack of light will, ultimately, be the cause of this. You will have to let them multiply until they reach out to a brighter area, or move them to a brighter area. This will be the only fix to the problem.
