Earlier in the year I bought a pack of three raspberry canes, each due to produce fruit at the different times. One cane grew a bit, produced leaves, three flowers and subsequent fruit in probably mid summer. One cane appears to have died and the third grew a few leaves but nothing else this year. Since they were only new this year and didn't cost much, I was happy enough and hoped they'd produce more next year.
However, the one which flowered has since produced 4 or 5 new canes. I assumed these would bear fruit next year but about a month ago they started to produce lots of flowers and they are now turning into fruit. What's going on with them and what should I do?! Leave them, cut them down to hope they work out the seasons for next year, or something else? I live in Greater Manchester.
Thank you for any help
