🌱 How to Care for Hoya Callistophylla to Prevent Mealybugs?

💧 How to Water

Only water again when the top 1-2 inches (2-5 cm) of the substrate are completely dry. Significantly reduce watering during the fall and winter. Use lukewarm, soft water and never allow water to sit in the decorative pot to prevent root rot.

☀️ Lighting

Bright and indirect light is ideal—a spot by an east or west-facing window, or a few feet away from a south-facing window. Direct midday sun causes leaf scorch, while insufficient light causes the characteristic vein patterns to fade and prevents blooming.

🪴 Ideal Soil

A coarse, airy substrate made of orchid bark, perlite, and some coconut husk or peat moss provides the necessary drainage. The pot must have a drainage hole, as the roots cannot tolerate standing water.
