I will be the first to admit that Hoya thailandica just does not like me very much. I have really struggled with it over the past 8 or 9 years and have had to start it over a number of times. In nature this plant besides living in very cool, humid, temperatures goes through a prolonged dry spell November through February. I have found that this plant requires very little water, and I just barely mist the soil every 10 days or so during the winter.
