Orchid Diseases

Orchids that are suffering from a disease may show symptoms like streaks, blotches, or even crinkling on their leaves, roots, or flowers.

If you suspect a problem, the first step is always to isolate sick plants so that the pathogen can’t spread to healthy plants.

With some diseases, you can remove the affected tissue with a clean knife and then treat the orchid with an appropriate bactericide or fungicide. In other situations, the best strategy is to dispose of the infected plants.

Cut down on future disease problems by creating a healthy growing environment and practicing good sanitation. Provide good air movement, avoid getting the foliage and flowers wet, and always use clean tools when transplanting and propagating your orchids.
