I have rescued my mother's hoya carnosa. It is probably about 10 years old and has been badly neglected over the past couple of years as her alzheimers has become more evident. I've watered it when I visit but we all know how warm and dry retirement homes can be.
Its been 15 years since I've had a hoya though I had sucess with them. I've pruned it back some but it badly needs repotting. I'm sure it is in the original pot with less dirt. Do they prefer to be pot bound or should I pot it up a bit? What type of fertilizer? I've used half strength orchid fertilizer once simply because it is all I have on hand right now.
