Passiflora caerulea also known as Passion flowers are a semi-tropical flowering and fruiting plant that brings some of the most unique flowers to your garden. With regular pruning, you can promote even thicker stems, increase flowers, and subsequently increase fruit production which is a nice late feature on there own. Trimming your shoots while they are growing will help them to remain in a specific area rather than taking over the entirety of your garden as they can vigours if not controlled somewhat.
How to prune passion flowers
Pruning young plants
Pruning your passion flowers should first be done when the plant is young so that you can train it properly. You can also help to promote sticker annual growth and produce many more flowers.
Pruning overgrown plants
Finally, if your plant is neglected or damaged you can rejuvenate it with hard pruning to around 2ft from the base of the plant. Spring in early spring but be prepared to get very little flowers for the next year or two. you will however be rewarded with lots of new shoots which you can use to form a permanent framework.
Training a newly planted passion flower
When your plant is newly planted, training the shoots will help to produce more vigorous growth. By the second year, pruning is incredibly important to create a stronger framework and at this point, you should cut your plant back to the strongest one or two buds above the previous years growth at the beginning of Spring. This will help to produce thicker growth as well as more peripheral stems for flowers. By the third year, your plant will have properly filled out to the point where it will produce many flowers and fruit.
When to prune
The best time to prune is the end of winter or early spring because your plant is not yet actively growing which means any cuts you make won’t hurt the flower buds. Remove any broken or diseased wood initially and then remove stems so that you cut back to a handful of healthy buds. You can choose to leave your climber unmaintained without doing a lot of pruning but this might result in fewer flowers and fruits and they can get a little scrambled. Trimming lightly on a regular basis can help keep the annual growth in check and to a permanent.
How to train passion flowers
Passion flowers grow incessantly and they will crawl up any vertical surface you have. Without some sort of support structure, they will creep across the ground and take over the space of any other plants.
To that end, it is important to give them some sort of support and properly trained the vines so that they remain wherever you want them to grow and nowhere else. This is something you will have to do regularly because of how quickly they grow. If you neglect them for even a few weeks you will find that you have almost a meter of growth in some cases that has perhaps clung somewhere you don’t want it to. Each of the vines we’ll wrap their tendrils around whatever surface is nearby and if you’re not careful and neglect training them, they will wrap their tendrils around one another and this will eventually choke out the airflow.
So give them something to wrap around, and you can even physically rap some of the thinner vines as they are growing and their tendrils will naturally secure the vine to whatever surface you have. It is best to wrap them around things like fences, trellises, or arbours. If you are aiming to cultivate fruit and flowers, you want to make sure that you train them properly and prune them in early spring not too hard so that the entire plant enjoys the proper amount of exposure to the sun which leads to more flowers and fruit.
