Cultivating Tips for Caulavola Colmanii:

3. Humidity: Aim for a humidity level of 50-70%. Use a humidity tray or humidifier if needed to maintain these levels.
4. Watering: Water thoroughly and allow the potting medium to dry slightly between waterings. Reduce watering during the winter months when the plant's growth slows.
5. Fertilizing: Use a balanced orchid fertilizer at half strength every two weeks during the growing season. Reduce feeding during the winter rest period.
6. Potting Medium: Use a well-draining orchid mix, such as bark or a combination of bark, perlite, and sphagnum moss. Repot every 2-3 years or when the medium breaks down.
