Banana passionflower problems — and how to fix them
Banana passionflower (Passiflora 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.
Aphids and whitefly
Colonies colonise new growth rapidly; blast off with water or apply insecticidal soap. Ants farming aphids worsen infestations — control ants with sticky barriers.
Root rot from overwatering
Yellow leaves with soft stems indicate waterlogged roots. Improve drainage immediately, remove affected roots, and allow soil to partially dry before watering again.
Invasive spread (outdoors)
Listed as an invasive weed in New Zealand, Hawaii, and parts of Australia. Do not plant near native bush; remove fruit before it ripens to prevent bird dispersal.
