Getting to Know the String of Pearls Plant

String of pearls plants, scientifically known as Curio rowleyanus, are known for their round, bead-like leaves that closely resemble a string of pearls. These plants are fast growers, adding about five to 15 inches in length each year. While they are commonly grown indoors as hanging plants, in their natural habitat, string of pearls plants grow as ground cover in the desert.

Apart from their unique leaves, string of pearls plants also produce white, cinnamon-scented flowers in the spring, although this is a rare occurrence when grown indoors. It’s important to note that these plants are toxic to humans and pets, so it’s essential to keep them out of reach of children and animals.

String of Pearls Care Tips

String of pearls plants are relatively low-maintenance, but they do have specific care requirements to ensure they thrive. Here are some key care tips for these unique succulents:

Light

String of pearls plants thrive in a combination of direct and indirect sunlight, receiving about six to eight hours of light each day.
Place them in direct sunlight during the morning hours and move them to a spot with diffused light or partial shade in the afternoon.

Soil

Use a well-draining succulent potting soil or a cactus potting mix for your string of pearls plants.
A mixture of potting soil and sharp sand in a 3:1 ratio can also be beneficial to prevent root rot.
Ensure the container has ample drainage holes to prevent waterlogging.

Water

Keep the soil lightly moist during the growing season (spring and summer) and reduce watering in the winter.
Water the plant once every seven to 14 days, depending on the climate and the type of pot.
Check the soil moisture by touching the top inch of soil; if it’s dry, it’s time to water.

Temperature and Humidity

String of pearls plants prefer warm temperatures above 70 degrees Fahrenheit in the growing season and cooler temperatures of 50 to 60 degrees Fahrenheit in winter.
Avoid high humidity environments, as these plants thrive in low humidity conditions.

Fertilizer

Feed your string of pearls plants biweekly during the growing season with a diluted, balanced liquid fertilizer.
Reduce fertilizer frequency to every six weeks during the plant’s dormant period in winter.

Types of String of Pearls Plants

Apart from the classic string of pearls plant (Curio rowleyanus), there are several closely related species that feature variations in leaf shape. These include Curio radicans, Curio herreanus, and Curio citriformus, each with its unique characteristics that add diversity to your succulent collection.

Pruning and Propagating String of Pearls Plants

To maintain the health and appearance of your string of pearls plant, regular pruning and propagation are essential. Here are some tips on how to prune and propagate these succulents:

Pruning

Use sterilized scissors or pruners to trim off any dead or overgrown stems, as well as stems lacking leaves.
Prune leggy branches to promote bushier growth and propagate new plants from the cuttings.

Propagating

String of pearls plants are easily propagated from stem cuttings, either in soil or water.
Propagation is best done in spring, summer, or early fall, allowing the cutting to root in about three to four weeks.

Repot the plant in the beginning of spring using a fast-draining succulent soil mix.
Choose a pot with adequate drainage holes, and position the plant in a slightly larger pot to allow room for growth.
Repotting annually is recommended, but after a few years, it’s better to propagate a new plant from cuttings.
