I have had this Hoya for ??? 5-8 years. Don't think it has ever been re-potted (maybe once a few springs ago) there are a few "tendrals" that have much more curl in the leaves than the rest of the plant. Hopefully the pictures will aid in Identification. I would love to know how to re-pot it best. It is neglected because it has lived so long in this pot and flowers every summer so I have been scared to re-pot since I don't know its soil needs
