Q.
Why are my passionfruit puckered and falling while still green?

A.
Possible causes include irregular watering, insufficient feeding, insect infestation, sudden change in temperature, poor pollination.
Make sure the vine is regularly watered, mulch around it to help conserve soil moisture.
Feed with Tui Citrus Food or Tui Enrich Fruit, Citrus, Tree & Shrub fertiliser. Passionfruit vines grow very quickly over a short period of time and require regular feeding in the growing season.
Passion vine hopper is a problem in summer, they are a sucking insect, the best way to control them is with a hose as they are very hard to control with an insecticide. Make sure the vine is well watered and regularly fertilised as when it gets stressed that is a signal to insects such as passion vine hopper that the plant is weak and they will move in quickly.
