How to prune passion flowers

Passion flowers (Passiflora) are rigorous, evergreen climbers that thrive in sunny, sheltered positions. The exotic flowers come in a variety of colours, but white and purple are most common in the UK. Here’s how to prune your passion flower for a healthy display of brightly coloured blooms, year after year.

The best time to prune your goji is spring. Wait until the buds begin to break, as it will be easier to see where any stems have died back over winter. 

As your plant grows, you’ll get the best results by training it against a wall, fence, trellis or obelisk. Simply tie in the loose stems to secure.

  • • To prune your passion flower, start by removing any dead or damaged shoots.

  • • Reduce the remaining stems to fit the growth to the available space, forming a fan-shaped framework that should be tied in to its supports with soft ties.

  • • After flowering, cut back any flowered shoots to two buds away from the previous year’s framework of stems. 

  • • Try not to prune any harder than this – hard pruning may forfeit any flowers in the following year.

  • • If your passion flower gets frost damage, when spring arrives, try cutting the stems back to around a height of 30cm, just above a good bud. With luck, this will stimulate new green shoots to appear.
