How to care for hoya carnosa

  • Light: Requires bright, indirect light for best growth and flowering. Can tolerate medium light, but flowering may be reduced. Some morning sun is beneficial.
  • Water: Water thoroughly when the top few inches of soil are dry. Allow soil to dry out almost completely between waterings, as it stores water in its leaves.
  • Soil: Needs a well-draining, airy potting mix, such as an orchid mix or a blend of potting soil, perlite, and bark. Good drainage is essential.
  • Temperature: Thrives in average room temperatures between 60-80°F (15-27°C). Protect from cold drafts and temperatures below 50°F (10°C).
  • Humidity: Enjoys moderate to high humidity, especially during flowering. Occasional misting or a pebble tray can be beneficial in dry environments.
  • Fertilizer: Feed monthly during spring and summer with a balanced liquid fertilizer diluted to half strength. Reduce or stop fertilizing in fall and winter.
  • Propagation: Propagated easily from stem cuttings. Cuttings can be rooted in water or directly in moist soil.

Is hoya carnosa toxic to pets?

Pet-safe. Non-toxic to cats, dogs, and humans. See our guide to toxic plants for cats and dogs.

Common problems

  • Lack of flowering or slow growth: Often due to insufficient light. Move the plant to a brighter location with consistent indirect light; mature plants also prefer to be somewhat root-bound to flower.
  • Yellowing leaves or leaf drop: Typically a sign of overwatering or poor drainage. Allow soil to dry more thoroughly between waterings and ensure pot has adequate drainage holes.
