Select a place that gets bright, indirect light. Don’t let their waxy foliage fool you. They are not succulents and can’t take harsh afternoon light. They will grow in lower light situations but it’s unlikely they will bloom.
Soil and Repotting
Potting soil with good air circulation is very important for Hoya. To create a perfect blend mix equal parts of Espoma’s organic Cactus Mix, Orchid Mix, and Perlite. Hoya like to be pot-bound or crowded in their pots. They will only need to be repotted every two or three years.
Water regularly with room-temperature water, spring through summer. Let the top layer of soil dry between watering. In the fall and winter growth naturally slows down and they won’t use as much water. Water sparingly during fall and winter, give them just enough that the soil doesn’t dry out completely. Too much water can cause flowers to drop.
Hoya are tropical plants that thrive in humid conditions. Use a humidifier to bring the humidity levels up, especially in winter when indoor air tends to be dry. A saucer with gravel and water also provides humidity as the water evaporates. Misting with room-temperature water also helps but avoid spraying the flowers.
