Water
Water the plant regularly, but be careful not to overwater it. Allow the soil to dry out slightly between waterings, and never let the plant sit in standing water. During the growing season, water the plant once a week. During the dormant season, reduce watering to once every two weeks.
Fertilization
Fertilize the plant once a month during the growing season, using a balanced orchid fertilizer. Be sure to dilute the fertilizer to half its recommended strength, as orchids are sensitive to high levels of nutrients.
Soil
Polystachya Ottoniana is an epiphytic orchid, which means it grows on other plants rather than in soil. It is typically grown in a potting mix that consists of bark, sphagnum moss, and perlite. The potting mix should be well-draining, as orchids are prone to root rot if the soil is too wet.
Sunlight
Polystachya Ottoniana prefers bright, indirect sunlight. Avoid placing the plant in direct sunlight, as this can cause the leaves to burn. If the leaves start to turn yellow, this may be a sign that the plant is receiving too much sunlight.
