Troubleshooting
Black Mission Fig problems — and how to fix them
Black Mission Fig (Ficus carica) 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.
Fruit souring
Overripe or split fruits ferment rapidly in humid conditions. Harvest at peak ripeness and improve air circulation.
Leaf rust
Yellow-orange pustules on leaves in humid conditions. Remove affected leaves and improve airflow; apply copper fungicide if severe.
Mediterranean fruit fly
Larvae damage ripening fruit. Use protein bait traps and harvest promptly when fruit is ripe.
Nitrogen excess
Over-fertilising promotes lush foliage at the expense of fruit. Use low-nitrogen feeds after initial spring application.
Gopher and root damage
Rodents attack roots in California gardens. Install wire root barriers when planting.
