- Granadillas need hand pollinating. Use a different flower to the one you want to pollinate ie don’t use the same flower to pollinate itself. Use a soft chicken/bird feather or a light paint brush.
- Shelley Gage Recently I put old pantyhose over my Granadilla fruits and so far it has stopped the snails which make pock marks on the fruit leading to rotting. Some of the fruit was hand pollinated and some set without any help.
