Prevention Tips for Healthy Dendrobium Orchids
1. Maintain Proper Hygiene
Regularly clean your orchid’s pot, tools, and workspace to prevent the spread of pathogens. Remove dead or diseased leaves promptly to reduce infection risk.

Isolate new orchids for a few weeks before introducing them to your collection. This helps prevent the spread of unseen diseases.
8. Regular Inspection
Inspect your orchids weekly for early signs of disease. Prompt action can prevent minor issues from becoming severe.
