Plant a passionfruit – or two! I talk with horticulturist Sabina Fielding-Smith about passionfruit, including Panama Red, Panama Gold, Nellie Kelly and Banana passionfruit. Almost every garden has space for one passionfruit vine, so try to find a suitable spot against a sunny fence or wall.
In the podcast, (click on the audio above) Sabina explains about:
– varieties to grow in different Australian climates, from cool to tropical
– grafted varieties
– how to prepare the soil and train your passionfruit, and how long your plant will last
“I get flowers but no fruit, not even with hand pollination”
The most common reasons for passionfruit vines having lots of flowers but no fruit are:-
1. Lack of pollinators, i.e, bees.
2. Temperatures too hot or cold during flowering.
3. Long periods of overcast weather during flowering –vines in southern Victoria are prone to this problem.
4. Growing in too much shade.
5. Not enough water during flowering.
6. Lack of boron or other trace elements.
One other reason for a lack of fruit on grafted vines can sometimes be that the vigorous rootstock has sprouted and outgrown the scion without the grower realising. Check the leaves on your plant.
The understock has a palm shaped leaf, whereas the Nellie Kellie has an oval shaped leaf if you’re not sure about this.
