Care tips
This Hoya requires bright, indirect light; avoid strong direct sun to protect its leaves and flowers. Water when the substrate is almost dry to the touch, reducing frequency in winter, and ensure the potting mix is very well-draining, such as an orchid or aroid blend. A common mistake is overwatering, which can lead to root rot, so it's better to underwater than overwater.
