Troubleshooting
Banana Passion Fruit problems — and how to fix them
Banana Passion Fruit (Passiflora tripartita var. mollissima) 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.
Invasive, rampant growth
It grows aggressively and self-seeds, becoming a serious weed in some warm regions. Prune hard, deadhead, and avoid planting where it can escape into the wild.
Cyanogenic unripe fruit and leaves
Green fruit and foliage contain cyanogenic compounds and are unsafe to eat. Harvest only fully ripe, yellow, soft fruit and keep pets away from the vine.
Powdery mildew and fungal leaf spot
Dense growth in damp, still air invites mildew and leaf spots. Improve airflow, avoid overhead watering, and thin congested growth.
Poor fruit set in cool or shaded sites
Insufficient warmth, light or pollinators reduce fruiting. Site in full sun and shelter, and hand-pollinate flowers if natural pollinators are scarce.
