Feed orchids twice a month with a balanced organic fertilizer, and give a nitrogen supplement such as fish emulsion at each feeding.
Pests and Diseases
Orchids are remarkably problem-free. Use insecticidal soap to control the most common pests: mealybugs, scale, and spider mites. If a plant shows signs of disease, isolate it, remove affected parts with a sharp, flame-sterilized knife, and watch for recurrences.
