Troubleshooting
Yellow Raspberry problems — and how to fix them
Yellow Raspberry (Rubus idaeus 'All Gold') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Raspberry beetle
Larvae tunnel into ripening fruit, leaving dried, maggoty drupelets. Autumn-fruiting types like 'All Gold' largely escape the worst because they crop after the beetle's egg-laying window.
Crumbly, seedy berries
Caused by drought during fruiting, poor pollination in cold weather, or raspberry mosaic virus. Keep plants watered and replace plants showing persistent crumbliness with certified virus-free stock.
Grey mould (botrytis)
Furry grey rot on ripe berries in wet, still conditions. Improve airflow, pick fruit promptly and remove any rotting berries to stop spread.
Chlorosis on alkaline soil
Yellowing leaves with green veins signal iron and manganese lock-out on chalky ground. Mulch with acidic organic matter and apply chelated sequestered iron.
Prevent yellow raspberry problems before they start
Most yellow raspberry issues are care-mismatch, not bad luck. Dial in the basics:
