String of Pearls is not just a jewelry term; it's also the name of the most popular hanging succulent plant that can bring a touch of elegance to your living space. The String of Pearls plant is the most popular hanging succulent among the Curio genus. The String of Pearls Senecio rowleyanus has spherical leaves that resemble small peas, which hold water and are ideal for arid conditions. They have a cool little translucent window in their round leaves that allows light to enter the leaf and reach the chloroplasts, which are responsible for photosynthesis. Here at Planet Desert, you can learn how to grow, propagate, and care for the String of Pearls.
Light and placement
Indoor care requires bright, indirect sunlight. If you don't have a spot with bright indirect light, you can also use artificial grow lights to provide the necessary bright light for your string of pearls. LED grow lights are a great option, as they emit the right spectrum of light for your succulent plant growth. Place the lights about 6-12 inches above these delicate pearl plants and keep them on for around 12-14 hours a day. If you are growing your string of pearls plants outdoors, they thrive in a full sunny environment, making them one of the best choices for container gardening. However, be cautious of exposing it to direct sunlight for extended periods, as it can scorch the delicate leaves. Remember, finding the perfect balance of light is key. Too little light can result in leggy growth and pale leaves, while too much direct sunlight can cause leaf burn.
Soil and watering
For the soil, you'll want to use well-draining sandy soil that allows excess water to flow through easily. Use a well-drained specialty soil mix, as this type of potting soil mix has been precisely developed to imitate well-drained desert soils. Avoid using standard potting mixes that contain too much moisture or nutrients. The commercial succulent mix is affordable and accessible online. Water thoroughly during the growing season, ensuring the soil stays slightly moist. Watering should be adjusted for indoor vs outdoor and season; in general, allow the soil to dry between waterings and avoid leaving the plant in standing water.
Temperature and humidity
When your succulent plant grows indoors, it prefers a warm temperature above 70°F during spring and 50° to 60°F in winter temperatures. Avoid placing it near drafty windows or in direct airflow from heating or cooling vents. Humidity should be low; the string of pearls can survive in any household setting.
Fertilizing and bloom
During the actively growing season (typically spring), you can use a natural NPK-balanced liquid fertilizer once a year with an equal mix of 5-10-5. If you want your string of pearls to bloom, overwintering is crucial; the white flowers have bright yellow anthers and long red stamens. In indoor conditions, blooming is rare but possible with regular feed, enough water, and light. The blooming period is relatively short but is a delightful sight to behold.
Pruning, propagation, and repotting
To prune your string of pearls, keep in mind that this trailing plant has delicate, trailing stems with small, bead-like leaves. Too much pruning can disrupt its natural cascading form. The best time to repot your String of Pearls is at the beginning of spring. Repotting can be done once a year. When repotting, take a pot larger than your previous size and use a shallow container to accommodate the plant's shallow root system. For propagation, the easiest method is by healthy stem cuttings; propagation from stem cuttings can be done in two ways: method one uses 3 to 4 cuttings pressed gently on the soil until roots form, and method two involves separating leaves from the stem and placing the stem on soil so growth nodes get immersed. Propagation from seeds is possible but more challenging. You can also layer for rapid propagation. Regular maintenance includes providing adequate light, ensuring drainage, and pruning to maintain shape.
Growing outdoors vs indoors and zone considerations
The String of Pearls can be grown indoors and outdoors. Outdoors, it can be grown in zones 9 and warmer, ideally in containers or as ground cover with morning sun and afternoon shade. Indoors, provide bright indirect light and avoid extreme temperatures. In zone 8 or lower, protect from cold drafts and consider winter indoor placement with enough light. Place in bright locations where indirect light is abundant and direct sun exposure is limited to prevent sunburn.
Troubleshooting and common issues
Pests are generally minimal, but mealybugs, aphids, whiteflies, and ants can be attracted to the plant. Overwatering can cause purple leaves and mushy stems, and root rot is a risk if roots sit in water too long. Brown blushing in intense sun is not true sunburn; the plant is simply adapting. If roots are mushy or blackish, trim dead roots and allow healthy roots to regrow. Water chemistry matters: letting tap water sit for 24 hours helps volatilize fluoride and chlorine; filtered water or rainwater is preferable. The String of Pearls is mildly toxic to pets if ingested, so place out of reach of curious animals and children.
Variegated string of pearls
The variegated string of pearls, Curio rowleyanus variegatus, displays leaves with green and creamy white colors, sometimes with pinkish tones. It is a trailing plant popular for hanging baskets or as a trailing accent in indoor gardens, adding elegance. It requires bright light, good drainage, and infrequent watering to prevent rot. Containers should have drainage holes, and use well-draining soil with 50% to 70% mineral grit such as coarse sand, pumice, or perlite. Variegated forms are more sensitive to intense sun and may benefit from more shaded conditions to preserve variegation.
Additional notes and comparison
What’s the difference between string of pearls and string of tears? The main difference is appearance: string of pearls has round bead-like leaves; string of tears (Curio citriformis) has elongated teardrop leaves. Both belong to the Curio rowleyanus group and share care fundamentals, including bright light, well-draining soil, and infrequent watering. The string of pearls is drought-tolerant and can grow quite rapidly under the right conditions, with a cascading habit that looks stunning in hanging pots or as a trailing accent.
- Common varieties include variegated string of pearls and string of tears; both require bright light and well-draining soil.
- Repot every 2-3 years or when growth slows; propagate via stem cuttings or layering.
- Keep away from pets and children when ingested; plant is mildly toxic.
All told, String of Pearls is an easy, but not too easy, plant to grow. With proper light, soil, and water management, these plants flourish and become stunning centerpieces in any indoor garden. They are commonly available at nurseries and garden centers specializing in succulents and cacti, and many growers offer a variety of forms including variegated types and related Curio rowleyanus members.
