Water your orchid once a week during the winter and twice a week during the hotter, summer months. Watering should be done during the day, not at night.
Fertilize your orchid fertilizers that contain nitrogen, phosphorus and potassium. These are elements similar to the ones they would receive in the wild from animal droppings and rainwater.
Repot your orchid as necessary, usually every 18 to 24 months. The pot size should be based on the size of the roots. Orchids like to be somewhat tight in their pots, according to BeautifulOrchids.com.
