Growing Hoya collina Part Three

The plant picked up during the summer of 2019 growing many new leaves in the summer greenhouse. So I decided to keep it around and hope for a better winter with it, but it was not to be! The winter of 2019/2020 was every bit as bad and maybe worse than the previous winter. I tried everything I could think of but I kept having to pull off yellowed sickly leaves. I so wanted to throw out this plant, but I had put so much time into it, I wanted to flower it before it went away.
