Capping the side shoots leads to stronger branching
Passion flowers grow from several strong main shoots, which can also lignify with age - provided they have not been pruned beforehand. The hoped-for blooming splendor can only be seen on the young (ie this year's) side shoots, which is why they should be shortened in autumn, but at the latest shortly before the start of the growing season. All you have to do is leave three to five eyes, the more the plant will sprout again and develop numerous branches. As a rule of thumb, the more new shoots and branches, the more flowers you can expect.

Remove dead flowers
If you are not necessarily hoping for fruits and seeds, you should remove the shoots with the dead flowers. The development of fruits and seeds costs the plant a lot of strength, and it fulfills its urge to reproduce by producing seeds. As a result, she invests less energy in her flowers. Removing that has faded ensures that you can enjoy the beautiful flowers of your Passiflora for a longer period of time. But don't worry: since passion flowers are usually perennial, you can look forward to the following year.
Prune passiflora in autumn
Passion flowers can grow very large: provided they have a large pot, a nice, sunny spot and plenty of water and fertilizer, the vigorous plants can quickly climb all the climbing aids they can get hold of. However, only a few Passiflora are hardy and should therefore be overwintered frost-free - in the house, in the apartment or in an unheated greenhouse. However, you do not need to worry about space problems, because you can cut back the plant drastically without worrying. The leading branches of older passion flowers can be shortened to around 15 to 20 so that they easily fit on the windowsill in the unheated bedroom.
Tips & Tricks
When pruning the plant, be sure to use both sharp and clean tools. A blunt knife or scissors would only injure the Passiflora unnecessarily and would also provide a gateway for fungi and other pathogens.
