Care Guide
Watering
Allow the soil to dry out completely between waterings. Hoyas are semi-succulent and prone to root rot if kept consistently soggy.
Sunlight
Provide bright, indirect sunlight. Some direct morning sun is beneficial, but harsh afternoon sun can scorch the leaves.
Soil and Fertilizer
Use a well-draining, airy potting mix, such as a blend of standard potting soil, orchid bark, and perlite. Feed with a balanced, diluted houseplant fertilizer during the spring and summer growing season.
Pruning
Do not cut off old flower spurs (peduncles), as Hoya flowers reappear on the same spurs year after year. Prune only to control leggy vines or shape the plant.
Propagation Methods
Cutting
Take a stem cutting with at least two or three leaves and a node. Root them in water, sphagnum moss, or a direct potting mix with high humidity.
Common Diseases & Pests
