Lighting: Provide bright, indirect light for Hoya Carnosa 'Crimson Queen.' It can tolerate some direct sunlight, but prolonged exposure may lead to leaf burn.

Watering: Allow the top inch of the soil to dry out before watering. Water thoroughly and let excess water drain away. Hoya Carnosa prefers slightly drier conditions compared to overwatering.

Temperature: Maintain temperatures between 60-80°F (15-27°C). Protect the plant from drafts and sudden temperature fluctuations.

Size: Hoya Carnosa 'Crimson Queen' can grow as a trailing or climbing plant, and its size will depend on its environment. Regular pruning can help control its size and shape.

Fertilizing: Feed the plant with a balanced liquid fertilizer diluted to half strength during the growing season (spring and summer). Reduce or cease fertilization in the fall and winter when growth slows.

Pet Friendly: Hoya Carnosa 'Crimson Queen' is generally considered non-toxic to pets. However, individual pets may react differently, and it's always a good idea to monitor them around any houseplant. If in doubt, consult with a veterinarian.

Ensure the pot has drainage holes, use well-draining soil, and repot when the plant outgrows its container. Prune occasionally to maintain a bushy and compact shape. Regularly check for pests such as mealybugs or aphids, and treat promptly if detected.
