String of Hearts: A Guide to Caring for This Lovely Trailing Plant

Understanding the String of Hearts Plant

The String of Hearts, scientifically known as Ceropegia woodii, is a captivating trailing plant native to southern Africa. It is widely cherished for its heart-shaped leaves, delicate variegation, and slender vines that cascade beautifully from shelves and hanging pots. This endearing succulent is not only attractive but also quite resilient and low-maintenance, making it a perfect addition to any indoor plant collection.

Optimal Lighting Conditions

For a thriving String of Hearts, lighting is crucial. This plant prefers bright, indirect light, as direct sunlight can scorch the leaves. However, a little morning sun can be beneficial. A north or east-facing window usually provides the ideal light conditions. If natural light is limited, consider using grow lights to supplement.

Watering Requirements

Being succulent-like in nature, the String of Hearts stores water in its leaves and stems, which allows it to be more drought-tolerant. Watering should be done sparingly—typically when the soil has dried out completely. Over-watering can lead to root rot, so ensuring good drainage is essential. During the winter months, reduce watering frequency as the plant goes into dormancy.

How to Tell When It’s Time to Water

To check if your String of Hearts needs water, feel the top inch of the soil. If it’s dry, it’s time to water. Alternatively, you can pick up the pot; a lighter pot usually indicates that the soil has dried out. Be sure to water thoroughly, allowing excess water to drain out of the bottom.

Soil and Repotting

The ideal soil for a String of Hearts is a well-draining mix, similar to that used for cacti and succulents. You can buy a pre-made mix or create your own by combining potting soil with perlite or sand to improve aeration and drainage. Repotting is infrequent, as the String of Hearts prefers a snug pot, but it may be necessary every few years or when roots start to outgrow the current container. The best time to repot is during spring or summer.

Fertilizing Your Plant

Feeding your String of Hearts is relatively straightforward. Use a balanced, water-soluble houseplant fertilizer, diluted to half the recommended strength, every month during the growing season, which typically spans spring and summer. Refrain from fertilizing in fall and winter when the plant’s growth slows down.

Pruning and Propagation

Pruning is seldom needed for this plant, although you may occasionally trim it to maintain its shape or encourage fuller growth. Regularly removing dead or yellowing leaves is also a good practice. As for propagation, the String of Hearts is quite amenable—it can be easily propagated from cuttings or by using the tubers that form on the base of the leaves.

Propagation Steps

Simply place a leaf-cutting or tuber on top of the soil, and with some patience and steady moisture, new growth should appear. This makes it simple to expand your collection or share with fellow plant enthusiasts.

Common Pests and Problems

Fortunately, the String of Hearts is not prone to many pests. However, mealybugs and aphids can occasionally be a problem. Regular inspection and wiping the leaves with a damp cloth can prevent infestation. If pests are spotted, treat the plant with insecticidal soap or neem oil.


The String of Hearts plant, with its elegant trails and charming foliage, is a delightful choice for both novice and seasoned plant lovers. By providing proper lighting, watering appropriately, and observing basic care practices, this hardy houseplant can be a long-lasting and spectacular feature in your home or office.
