How do you get your Hoya to bloom. I live in the Houston Texas area. My Mom had one which bloomed and this is a cutting from it. I almost killed it when she told me to put it in the hot sun to force blooms. It fried, lost all leaves, but constant nurturing and it is back and beautiful, but I have had it for more than 10 years with not a single bloom. What am I doing wrong. It stays on my open patio under roof and I bring it in during cold times.
