Why won't my passionfruit vine flower
About 2.5 years ago i threw some seeds from a shop bought passionfruit into the garden and they have grown huge and very healthy but have not produced a single flower. should I rip it out and try again or is there a chance they will give me some flowers/fruit
You certainly have a very healthy vine - what a pity it hasn't flowered or produced any fruit for you. The flowers do require insects for pollination. Heavy rainfall at a time when the vine is producing pollen can reduce the likelihood of pollination. The absence of bees and pollinating insects can also interfer with pollination. To encourage flowering this spring, you might like to apply a fertiliser that is high in potassium. One that we would suggest is Dynamic Lifter for Fruit & Citrus or Thrive Granular Plant Food for Citrus. I wouldn't take out your vine just yet. You might like to prune back the long straggly laterals now before you apply the fertiliser in spring. If the weather conditons are still cold or if there is any likelihood of a frost, wait until conditions improve before pruning. Good luck, I hope this year is 'the year' for your passionfruit vine.
