This is the Hoya that I was given at the entry gate to the Icheon Rice Festival last weekend in Seoul. Hoya's were always something that I had admired from afar and thought that I might own one day. Well... that happened before I knew it and I haven't had any education on the different types and how to grow them. I just sort'a know that some can not dry out, and that there are some that must dry out or they will rot. This one is planted in a sand/grit mix along with a bit of dirt and a smidgen of organic matter. It is much richer looking soil than the jacob's ladder and false aralia that I bought last week are in. I did not see any American style potting soil at any of the places that sell plants in my town or at the truck they were pulling all different kinds of plants from at the festival. As it is real humid here - over 50% 11 months of the year, I guess that plants need real sharp drainage to keep from rotting. Can you help me figure out how to care for this?
