Passionfruit infertility? No fruit on my passionfruit.
Now three years in, our passionfruit (on grafted root stock) is again producing flowers in abundance and looks a picture of perfection. It has yet to set a single fruit. I have corrected the ph level, added sulphate of potash (both suggested by the local nursery), fertilised and even spoken to it kindly.
In response, it continues to drop its spent flowers.
Any ideas friends?
