Troubleshooting
Goji Berry problems — and how to fix them
Goji Berry (Lycium barbarum) 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.
Slow to fruit
Young plants often grow vigorously for two to three years before cropping well; patience and full sun are needed, and pruning to an open framework speeds productive wood.
Suckering spread
Canes layer and sucker into surrounding ground; site away from borders or grow in a large container to contain its wandering habit.
Powdery mildew and rust
Dense, crowded growth in humid conditions develops mildew or rust on leaves; thin canes and improve airflow to reduce infection.
Bird and pest feeding
Ripe berries attract birds, and aphids gather on soft tips; net fruiting plants and tolerate or wash off light aphid colonies.
Prevent goji berry problems before they start
Most goji berry issues are care-mismatch, not bad luck. Dial in the basics:
