Hoya Kerrii “Sweetheart Hoya”

Native to Southeast Asia, this slow-growing, semi-succulent plant is a member of the Apocynaceae family. It’s often given as a symbol of love and affection due to its distinct heart-shaped leaves, which is why it’s sometimes called the Lucky-Heart Plant.

The Sweetheart Hoya is often sold as a single-leaf cutting in a small pot, and while it can stay as a single decorative leaf for a long time, given the right care, it will eventually grow into a trailing or climbing vine with multiple heart-shaped leaves. This plant is relatively low-maintenance, making it a popular choice for both beginners and experienced plant enthusiasts.

Plant Care for Hoya Kerrii “Sweetheart Hoya”

1. Light:

   • The Sweetheart Hoya prefers bright, indirect light. While it can tolerate lower light conditions, its growth will be much slower. If possible, place it near a bright window, but avoid direct sunlight, which can scorch its leaves.

2. Watering:

   • As a semi-succulent, the Sweetheart Hoya is quite drought-tolerant and prefers to dry out between waterings. Water the plant thoroughly when the top 1-2 inches of soil are dry, but ensure the pot has proper drainage to avoid soggy soil. Overwatering can lead to root rot. Reduce watering in the winter when the plant’s growth slows.

3. Humidity:

   • The Sweetheart Hoya can tolerate average household humidity, but it will appreciate slightly higher humidity levels, especially in dry climates. You can mist the plant occasionally or place it near a humidifier, but it will generally thrive in normal indoor conditions.

4. Temperature:

   • The plant thrives in warm temperatures between 65°F to 80°F (18°C to 27°C). It’s sensitive to cold drafts and should not be exposed to temperatures below 50°F (10°C). Avoid placing the plant near air conditioning units or heaters.

5. Soil:

   • Use a well-draining potting mix for your Sweetheart Hoya, such as a cactus or succulent mix. You can also mix standard potting soil with perlite or orchid bark to improve aeration and drainage.

6. Fertilizing:

   • Fertilize the plant with a balanced, water-soluble fertilizer once a month during the growing season (spring and summer). Avoid fertilizing during the winter when the plant is dormant. Over-fertilizing can lead to salt buildup in the soil, so it’s best to err on the side of caution.

7. Flowering:

   • Given proper care and bright light, the Sweetheart Hoya may produce clusters of small, star-shaped flowers. These flowers are typically white or pale pink with red centers and have a waxy texture. However, flowering is rare indoors, and it may take several years for a Sweetheart Hoya to mature enough to bloom.

8. Pruning:

   • Pruning is generally unnecessary for the Sweetheart Hoya, but you can trim back leggy growth if you prefer a more compact shape. If your plant develops a long vine, be careful not to prune the growing tips, as this is where new leaves and flowers will emerge.

9. Repotting:

   • Repotting is rarely needed, as the Sweetheart Hoya prefers to be slightly root-bound. If you notice that the plant has outgrown its pot or the soil isn’t draining well, you can repot it every 2-3 years in fresh soil.

10. Propagation:

    • The Sweetheart Hoya can be propagated through stem cuttings. Cut a segment of the vine with at least two leaves and nodes, let it dry for a day, and then plant it in well-draining soil or place it in water until roots develop.

11. Pest Control:

    • While relatively pest-resistant, the Sweetheart Hoya can occasionally attract mealybugs, aphids, or spider mites. Inspect the plant regularly and treat any infestations with insecticidal soap or neem oil.

12. Toxicity:

    • The Hoya Kerrii is considered non-toxic to pets and humans, making it a safe choice for homes with animals or children.
