Hoya rangsan plants like heaps of bright, indirect sunlight and will be right at home if they can make contact for at least 6 to 8 hours each day (indirect contact, that is!). This plant should not be exposed to direct sunlight, as it can lead to leaf burn.


Water your Hoya rangsan every 1 to 2 weeks during the spring and summer. In the fall and winter months, you can reduce how often you are watering this plant. During this time, you can water it every 2 to 4 weeks.


Hoya rangsan prefer a well-draining potting mix that lets extra water to flow out away from the roots. The mix can include a combination of peat moss, perlite, orchid bark, and pumice.

For your Hoya rangsan, aim for a humidity level of around 50% to 60% (or even higher). This plant loves humid environments! To increase humidity levels, you can group plants together, use a humidifier, provide a pebble tray, or regularly mist! Additionally, you should avoid your plant near any drafty areas, as it can cause the air to dry out and reduce humidity levels for your plant. 


A Hoya rangsan should be fertilized every 4 to 6 weeks during the spring and summer. In the colder months, you can reduce or even pause on fertilizing your plant. We suggest that you use a balanced liquid fertilizer with the equal ratio of exactly 10-10-10 or 20-20-20. Avoid getting the fertilizer on the leaves, as it can cause leaf burn!
