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. year ago we have 1 passion fruit has a lot of flower but never harvest any fruit finally we chop down the vine. Recently someone gave us 4 baby vine passion fruit (about 1-2 months old about 4 feet tall) we make a gazebo iron house and plant 1 vine at each corner.
