Hoya kerrii, commonly known as the Sweetheart Plant or Heart-leaf Hoya, is a charming and popular houseplant cherished for its thick, succulent, heart-shaped leaves. Here are some care tips for Hoya kerrii:

1. Light: Hoya kerrii prefers bright, indirect light. It can tolerate some morning sun, especially in cooler climates, but avoid direct sunlight as it can scorch the leaves. Insufficient light may result in slower growth.

2. Temperature: It thrives in temperatures between 60-80°F (15-27°C). Protect it from drafts and sudden temperature fluctuations, especially during colder months.

3. Watering: Allow the soil to dry out slightly between waterings. Hoya kerrii is drought-tolerant but prefers consistently moist soil during the growing season (spring and summer). Reduce watering in fall and winter, allowing the top inch or so of soil to dry out before watering again.

4. Humidity: It tolerates average indoor humidity levels but benefits from slightly higher humidity. You can increase humidity by misting the leaves or placing a humidity tray filled with water and pebbles nearby.

5. Soil: Use a well-draining potting mix designed for succulents or a mix of peat, perlite, and orchid bark. Good drainage is crucial to prevent root rot.

6. Fertilizing: Feed with a balanced liquid fertilizer diluted to half-strength every 4-6 weeks during the growing season. Reduce feeding in fall and winter when growth slows down.

7. Pruning: Trim back any leggy growth to maintain a compact shape. You can also prune to promote branching and fuller growth.

8. Support: Hoya kerrii can be trained to climb a support structure or left to trail from a hanging basket. Use gentle ties or clips to support the vines without damaging them.

9. Pests: Monitor for common houseplant pests such as spider mites and aphids. Treat infestations promptly with insecticidal soap or neem oil.

10. Propagation: Hoya kerrii can be propagated from stem cuttings. Take 4-6 inch cuttings with at least one leaf node, allow the cut end to callous for a few days, and then plant in a well-draining potting mix. Rooting typically occurs within a few weeks to a couple of months.

By following these care tips, you can enjoy the unique beauty of Hoya kerrii's heart-shaped leaves and its easy-care nature as a delightful addition to your indoor plant collection.
