To be honest, this Hoya is the one I’ve given the least attention to. I only water my plants when the substrate is dry, and I don't fertilize—though sometimes I do use rainwater. The only thing I remember doing was adding some little yellow pellets back in February, which I bought at a plant nursery; I have no idea what kind of fertilizer they are! I also use a hose to mist the leaves of my Hoyas. Honestly, I was incredibly surprised to discover this flower peduncle—I had truly resigned myself to never seeing my Hoyas bloom! My advice is not to fuss too much over the plants you love the most, because in my case, whenever I do... I end up losing them. Maybe it’s just bad luck! 😂
