Shrivelling Sweet Granadila Flowers

Question

I have a sweet granadila vine that has produced many flower buds. Problem is, the flower buds do not open fully, they shrivel and eventually drop to the ground. What could be the problem and how do I fix this?

Answer 1

The sweet granadila is the common form of passiflora and its care is somewhat different. It doesn't like very hot weather, but according to your average temperatures, Nairobi doesn't have hot weather. I wonder if it is getting enough water. There is some kind of environmental stress or there is some type of bud mite affecting the blooms. This article gives tips on care. Compare those to yours:
