This Hoya is potted in a coco husk plug with a potting mix consisting of coco coir, orchid bark, perlite and worm castings. We do not recommend removing from the coco husk plug.
Light: Bright indirect light, meaning the plant sees the sun for 0-4 hours per day - this could be through trees or a translucent curtain, it’s important for the plant to see the sky in order to thrive. Hoya callistophylla would appreciate 1-2 hours of direct light.
Water: Allow the majority of the mix to dry out as the mix is traditionally quite chunky, water will usually flow through quite easily. Be sure to thoroughly moisten the substrate. Pour water slowly over the top of the substrate and allow the water to pass through the drainage holes.
Potting mix: A chunky well draining mix composed of coco coir, perlite or vermiculite, orchid bark, sphagnum moss and worm castings; you could also add some horticultural charcoal to this epiphytic mix.
Fertilising: Feed your plant every few waterings during the growing season or when you observe active growth. You can dilute fertiliser to half the recommended amount but never add more.
Humidity: Hoya would prefer higher humidity, between 60-80% but do well to adapt to average home humidity. You can increase humidity by placing the plant on a watered pebble tray or using a humidifier.
