Care Guide
Hoya carnosa Care Guide ### Light Place your Hoya in bright, indirect light. While it can tolerate some direct morning sun, harsh afternoon rays can burn the foliage. Insufficient light will prevent the plant from blooming. ### Watering Allow the potting medium to dry out almost completely between waterings. When you do water, soak the soil thoroughly and ensure all excess water drains away. Overwatering is the most common cause of failure. ### Soil Use a well-aerated, chunky mix. A combination of one part potting soil, one part orchid bark, and one part perlite is ideal for providing the drainage and air circulation these epiphytic roots require. ### Flowering Tips Do not prune the flower stalks, known as peduncles, after the blooms fall. Hoya carnosa will re-bloom from these same structures year after year. ### Maintenance Keep the leaves dust-free by wiping them with a damp cloth. This helps the plant photosynthesize efficiently and keeps pests like mealybugs at bay.
