String of Hearts Care & Growing Guide
Caring for a String of Hearts (Ceropegia woodii) is relatively straightforward, making it an excellent choice for both novice and experienced plant enthusiasts. This succulent vine thrives in bright, indirect light and prefers to dry out slightly between waterings, mimicking its natural habitat in South Africa.
When it comes to watering, it’s essential to strike a balance. Allow the top inch or two of soil to dry out completely before watering thoroughly. During the growing season (spring and summer), you may need to water more frequently, while in winter, reduce watering to prevent overwatering and root rot. The String of Hearts is drought-tolerant and can withstand periods of neglect, but consistent care will result in healthier, more vigorous growth.
Fertilization should be done sparingly, as the String of Hearts doesn’t require heavy feeding. Use a balanced, water-soluble fertilizer diluted to half strength once a month during the growing season. In terms of soil, a well-draining succulent or cactus mix is ideal. This plant appreciates good air circulation around its roots, so choose a pot with drainage holes and consider adding perlite or coarse sand to improve drainage. Regular pruning can help maintain the plant’s shape and encourage bushier growth, while propagation through stem cuttings or tubers is an easy way to expand your collection.
Soil
The String of Hearts (Ceropegia woodii) thrives in well-draining soil with a slightly acidic to neutral pH range of 6.0-7.0. The ideal soil composition should be a mix of regular potting soil, coarse sand, and perlite or pumice to ensure excellent drainage. A commercial cactus or succulent mix can also work well.
The soil should be light and airy to prevent water retention and root rot. Adding organic matter like coco coir or peat moss can help retain some moisture while still allowing for proper drainage. The ideal soil acidity range is slightly acidic to neutral, but the plant can tolerate a wider range if other conditions are optimal.
