Ok, I dont know if anyone here has a Passion Flower plant but if you have here are a couple of tips.

1) To promote flowering starve the palnt of water for as long as you dare, then water well and feed. You should see a good inprovement in the flowering rate.Why? The plant has a survival instinct built in, by starving it of water it thinks it may die so must produce offspring!!!

2)To improve the fruit production from the flowers use a soft brush to collect and distribute the pollen.


Good luck, these work for me.
