Troubleshooting
Passiflora alata problems — and how to fix them
Passiflora alata (Passiflora alata) 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.
Cold sensitivity
Very frost-tender — needs minimum temperatures around 10-13°C; sudden chills cause leaf drop or dieback, so overwinter in a warm, heated space.
Shy flowering in low light or with excess nitrogen
Too little light or over-feeding with nitrogen gives lush foliage but few flowers; provide bright light and a high-potash feed to promote blooms.
Greenhouse pests
Red spider mite, whitefly and mealybug thrive in warm, dry indoor air; maintain humidity, inspect regularly and use biological controls or insecticidal soap.
Vigorous, tangled growth
Grows fast and can quickly smother its support; prune and train regularly through the growing season to keep it manageable and flowering well.
