Fertilize: To maintain japanese stream orchid, use orchid-specific fertilizers with low nitrogen, applying diluted solutions bi-monthly during growth and reducing in dormancy. Seasonal adjustments are necessary, and watering before fertilization aids absorption while preventing root burn. Rinse excess to prevent salt buildup.
