Water: Hoya pubicalyx thrives in high humidity and is common in tropical rainforests. It prefers consistent moisture, with watering recommended weekly. A well-draining soil mix is essential to prevent waterlogging and root rot, making it a popular choice for indoor environments.

Fertilize: Feed hoya pubicalyx with succulents and cacti food every 4-6 weeks during spring and summer at half-strength for optimal growth. In winter, reduce feeding. Water hoya pubicalyx first to avoid root damage, ensuring proper nutrition for a thriving, blooming plant while preventing over-fertilization risks.

Propagation: Hoya pubicalyx is a favored indoor tropical plant known for its lush foliage and blooms. Propagation primarily involves leaf cuttings; choose a healthy leaf and allow the cut end to callus before planting in well-draining soil. Maintain consistent moisture and warmth, avoiding overwatering.

Repotting: For hoya pubicalyx, repot every 2 years in spring using a container one size larger with good drainage. After repotting, provide bright, indirect light and maintain humidity. Water when the topsoil is dry. This climber requires attentive care post-repotting to thrive.
