Orchids are not only decorative but also relatively sensitive when it comes to plant diseases. The Phalaenopsis or butterfly orchid is no exception. Treatment is possible for some diseases, but unfortunately not for others.
What diseases are common in Phalaenopsis orchids and how to treat them?
Phalaenopsis diseases such as root rot, sunburn, leaf spot, mosaic virus or wrinkle growth can be caused by incorrect location, too much or too little water and pests. Treatment varies - sometimes affected parts can be removed or fungicides can be used.
What do butterfly orchids often suffer from?
The most common diseases affecting Phalaenopsis are sunburn and root rot. The former occurs easily if the Phalaenopsis is placed in a south-facing window with direct sunlight at midday. Root rot, on the other hand, is usually caused by too frequent watering. In both cases, however, it is easy to help if the damage is discovered early.
Leaf spot diseases can sometimes be easily confused with sunburn, but the trigger here is fungi of the genera Cercospora and Colletotrichum. When an infestation occurs, yellowish, reddish, brown or black spots appear on the leaves, often with a dark edge. With the mosaic virus, spots initially only appear on the underside of the leaves. Infected plants are almost impossible to save.
Common diseases of Phalaenopsis:
- Leaf spot disease
- Crinkled or accordion chews
- Mosaic virus
- Sunburn
- Black or root rot
How are sick phalaenopsis treated?
Check the Phalaenopsis for visible pests and wet roots. Pests can usually be controlled biologically. You should cut off wet roots. Fungicides help against fungal pathogens, but only on mildly to moderately affected plants. It is best to cut off affected leaves immediately to prevent the pathogens from spreading. If the infestation has already progressed too far, treatment is often no longer successful.
Can I protect my Phalaenopsis from diseases?
You can prevent your Phalaenopsis from becoming sick or attacked by pests in the first place. The most important thing is a suitable location. It should be warm and bright, but not expose the Phalaenopsis to direct sun.
In addition to the location, good care is of course also important for he althy plants. For Phalaenopsis, this means moderate watering and careful use of fertilizer. Too much of both damages the sensitive orchid, as does cold drafts.
Tip
The first step in treating your Phalaenopsis is identifying the cause. Only when you know what the plant is suffering from can you help it.
