Why hasn't my 3 year old passionfruit fruited?

My two or three year old passionfruit has not fruited but this season there are only 2 or three green fruits. Enclosed two photos show two types of vines, leaves and flowers. My vine grows vigorously on a north south fence backed onto a chook yard and gets plenty of sun. I have not pruned it. I have mulched and added dynamic lifter and Seasol but probably not enough. What is the problem please? Only one photo seems to have attached.

Hello Noreen,

The two types of vines (including flowers) you are seeing from your plant are likely to be from the scion stock (the plant variety above the graft that is intended to produce fruit) and from the root stock (the plant variety below the graft intended to provide a hardy, disease resistant root system). Sucker vines growing from the rootstock (below the graft) should be removed carefully at their base with a sharp blade. Lack of fruit set may be more likely in a younger plant, but correct nutrition is usually required to support optimum flower and fruit production. We recommend Yates Dynamic Lifter Plus Fruit Food as a complete fertiliser, along with Yates Fruit and Flower Booster Liquid Potash for more targeted nutrition supporting flower and fruit production. Kind regards, Matt Yates Consumer Advice Horticulturalist
