Hoyas are easy to care for plant with average water needs and can be sensitive to over-watering. They prefer sandy well-drained soil and bright indirect light. Pests include scale insects, mealybugs and red spider mites. Fertilise every 1-2 during spring and summer.


While the hoya may be non-toxic to cats, fertilisers and pest control used on or around the plant may be potentially toxic. Ingestion of large volumes of hoya can potentially lead to a gastrointestinal obstruction but most cats seem to favour plants with strappy leaves and should leave hoya alone. If you do have a cat who is interested in eating the plant, consider moving it to another location the cat cannot access and bring in some cat-friendly plants such as catnip or cat grass.
