The String of Hearts (Ceropegia woodii), also known as the Chain of Hearts or Rosary Vine, is a charming trailing succulent plant with cascading vines adorned with small, heart-shaped leaves. Here are some care tips for the String of Hearts:

1. Light: String of Hearts prefers bright, indirect light. It can tolerate some direct sunlight, but too much can scorch the leaves. Insufficient light may lead to leggy growth.

2. Watering: Allow the top inch or two of the soil to dry out before watering. Water sparingly, especially during the winter months when the plant is in a semi-dormant state. Overwatering can lead to root rot, so it's crucial to let the soil dry between waterings.

3. Soil: Use a well-draining potting mix, such as a cactus or succulent mix. Adding perlite or sand can further enhance drainage. A lightweight mix prevents water from lingering around the roots.

4. Temperature: String of Hearts prefers temperatures between 60-75°F (15-24°C). It can tolerate slightly cooler temperatures but should be protected from frost.

5. Humidity: String of Hearts is adaptable to normal household humidity levels. It doesn't require high humidity to thrive.

6. Container: Choose a container with drainage holes to prevent waterlogging. Hanging baskets or containers with a trellis are ideal for showcasing the trailing vines.

7. Fertilization: Feed with a balanced, diluted liquid fertilizer every 4-6 weeks during the growing season (spring and summer). Reduce fertilization during the fall and winter when growth slows down.

8. Pruning: Trim the vines to control the plant's size and encourage bushier growth. You can also pinch back the growing tips to promote branching.

String of Hearts is a popular choice for hanging baskets or trailing from shelves due to its graceful cascading vines. Its distinctive heart-shaped leaves and ease of care make it a favorite among succulent enthusiasts and indoor plant lovers.
