This Fiji Native Is A Bear To Flower

I recently posted a video of Hoya vitiensis on YouTube and one of my subscribers suggested that this is a plant that requires good quality soil with a slightly acid pH range. He indicated to transplant it into a product called Ocean Forest. I have now purchased a bag and look forward to working with it. He also indicated that it is a plant that flowers as the days are shortening, which follows my experience with the plant.
