Troubleshooting
Tongue of Fire Bean problems — and how to fix them
Tongue of Fire Bean (Phaseolus vulgaris 'Tongue of Fire') 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.
Poor pod set
Excess nitrogen or extreme heat reduces beans. Avoid high-nitrogen feed and water steadily through bloom in hot spells.
Seed rot in cold soil
Direct-sown seed rots in cold, wet ground; wait for soil above 16°C and sow into warm, moist soil.
Grey mould on drying pods
Damp, crowded conditions invite botrytis. Space plants, ensure airflow, and harvest dry pods promptly in wet weather.
Aphids and bean beetles
Check leaf undersides; treat early with insecticidal soap or hand-pick, as they spread bean mosaic virus.
