Originally from Madagascar, the Christ's thorn is considered to be quite robust and easy to care for. So he is relatively rarely sick or attacked by pests. Last but not least, it owes this to its toxicity, which deters many of the pests.

The Christ thorn does not like its location, it sheds leaves

What diseases does the Christ thorn suffer from most often?

One thing that can make the Christ's thorn very difficult is root rot. It is mostly a result of waterlogging and/or overwatering. As a first aid measure, it is advisable to repot the Christ thorn. Remove all rotten and soggy root parts and place the plant in dry substrate. Pour the soil very carefully and refrain from further watering for a few days.

The leaves of the Christ thorn also occasionally fall off. If there are only a few leaves at the beginning of the dry dormancy, then this is not a cause for concern. If, on the other hand, all the leaves suddenly fall off, you should investigate the cause.

Your Christ thorn probably doesn't like its location. It is too warm, too cold or too dark. Put it in an airy, bright place, for example in the garden, and it will recover fairly quickly.

How can I prevent diseases and pests on the Christ thorn?

The best prevention against pests and all kinds of plant diseases is good care and the right location. If a plant feels comfortable in its place, then it is also healthy and robust.

For the thorn of Christ this means that it is in a light and warm, well-ventilated place. It should be watered regularly but not too much, and only very little when it is dry. During the growth phase, fertilize your Christ's Thorn about every two weeks.

Tips for staying healthy:

  • Location: warm, light, airy, slightly cooler during the dry dormant period
  • water: regularly, moderately in summer, sparingly in winter
  • fertilize: only during the growth phase
  • Humidity: rather low to medium

tips

Powdery mildew can occur in high humidity, especially in combination with heat. Isolate the affected Christ's thorn and remove all affected parts of the plant.
