Don't panic if your Passiflora suddenly turns yellow leaves, there are usually no dangerous diseases behind it. With a little extra care, the passion flower will quickly feel good again.
Why does my passion flower have yellow leaves?
Yellow leaves on Passiflora can be caused by incorrect watering and fertilization, waterlogging or drying out. In spring and summer, care should be taken to ensure sufficient water supply and fertilize weekly, but individual yellow leaves are normal in autumn and winter.
The cause is often incorrect watering and fertilization
Yellow leaves on Passiflora in spring and summer are usually an indication of either too much or too little water. You should be especially careful when it comes to waterlogging, as the plant doesn't like it at all. Therefore, ensure good drainage in the pot, for example by placing a layer of expanded clay (€19.00 on Amazon) under the actual substrate. The passion flower also doesn't dry out because it needs a lot of water, especially during the flowering period - the plant is a heavy feeder. That's why it's better to fertilize the passiflora weekly in summer instead of just every two weeks, as stated in many guides. Then you will be rewarded with many beautiful flowers.
Tips & Tricks
In autumn and winter, however, a few yellow leaves are completely normal. Pluck them off as soon as you notice them.
