Troubleshooting
Bignay problems — and how to fix them
Bignay (Antidesma bunius) 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.
No fruit on a lone tree
Bignay is usually dioecious, so a solitary female sets no fruit without a nearby male; plant both sexes or a known self-fertile clone.
Cold damage
Frost-tender and damaged below about 5°C; protect or move containers indoors before cold weather.
Fruit drop
Caused by water stress or temperature swings during fruiting; maintain steady moisture and warmth while berries develop.
Fungal leaf spot
Occurs in stagnant, very humid conditions; improve airflow, avoid wetting foliage late in the day and remove affected leaves.
Prevent bignay problems before they start
Most bignay issues are care-mismatch, not bad luck. Dial in the basics:
