Troubleshooting
Sweet Granadilla problems — and how to fix them
Sweet Granadilla (Passiflora ligularis) 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.
Heat intolerance
Unlike lowland passion fruit, it struggles in prolonged high heat, dropping flowers and fruit; site it where summers are mild or give afternoon shade and cool root runs.
Poor pollination
Large flowers need big bees or hand-pollination for good set; transfer pollen by hand in the late morning when stigmas are receptive.
Root and collar rot
Wet, poorly drained soil causes fungal root and collar rots; plant high in free-draining ground and avoid overwatering.
Aphids and viruses
Aphids spread debilitating passionflower viruses that mottle leaves and deform fruit; control aphids early and remove badly virused vines.

Most sweet granadilla issues are care-mismatch, not bad luck. Dial in the basics:
