Since they are semi-succulent epiphytic plants, Hoya Obovatas grow well in areas with regular misting or high humidity levels. The humidity level should be kept at about 60 percent and in temperatures ranging between 15° C to 29° C. However, during winter, you will need to change the temperature and humidity levels. Avoid placing your Hoya plant too close to heat vents, drafty windows, and fans to prevent exposure to extreme temperatures. Alternatively, you can decide to cluster other household plants with the Hoya Obovata or use a humidifier.
