Troubleshooting
Passiflora quadrangularis problems — and how to fix them
Passiflora quadrangularis (Passiflora quadrangularis) 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.
Poor fruit set
Often inadequate pollination or low humidity and heat; hand-pollinate flowers and ensure warm, humid growing conditions.
Excess leafy growth
Too much nitrogen produces lush vines but few flowers; switch to a high-potash feed and reduce nitrogen.
Fungal leaf spot
Dense, humid foliage encourages spotting and blight; improve air movement, avoid wetting leaves and remove affected growth.
Root rot in cool, wet soil
Cold, waterlogged compost rots the roots; provide sharp drainage and water sparingly in cooler periods.
