The Variegated String of Pearls plant (Curio rowleyanus ‘Variegata’) is a popular succulent. It is known for its unique, bead-like leaves with splashes of white, yellow, or pink. Its cascading growth habit makes it ideal for hanging displays.
Variegated String of Pearls Care
Light Requirements
Variegated String of Pearls thrives in bright, indirect light, essential for its vibrant coloration. An east-facing window offers gentle morning sun. South or west-facing windows require filtered light to prevent scorching. Too much direct sun can burn the pearls and fade variegation. Insufficient light causes leggy growth with sparse pearls, and the variegation may diminish.
Watering Practices
Correct watering is crucial, as overwatering often causes decline. Use the “soak and dry” method: water thoroughly until it drains, then let the soil dry completely before rewatering. Plump pearls indicate hydration; shriveled pearls signal thirst. During winter dormancy, reduce watering to about once a month, as needs decrease.
Soil Needs
Well-draining soil is essential to prevent root rot. A specialized succulent or cactus potting mix is ideal due to its sandy, fast-draining composition. For better aeration, amend regular potting mix with perlite or pumice. The pot must always have drainage holes to ensure excess water escapes.
Temperature and Humidity
This succulent prefers average room temperatures, between 70°F and 80°F during its active growing season. It tolerates typical indoor humidity and does not require high levels; excessive humidity can lead to fungal issues. Protect the plant from sudden temperature drops or cold drafts, as it is not tolerant of freezing conditions.
Fertilizing
During spring and summer, a light fertilizer application supports healthy growth. Use a balanced liquid fertilizer, diluted to half or quarter strength, every two to four weeks. Avoid over-fertilizing, which can cause nutrient burn. Cease fertilization entirely during winter dormancy.
Pruning and Repotting
Pruning encourages fuller growth, maintains length, and removes unhealthy sections. To promote a bushier appearance, trim vines just below a leaf node, where new growth emerges. Remove dead, yellowing, or leggy stems to redirect the plant’s energy towards healthy development.
Repot when the plant becomes root-bound, usually every two to three years. Repotting is best done in spring or early summer. Choose a pot one or two inches larger with drainage holes. Gently remove the plant, handle roots carefully, and use fresh, well-draining succulent mix. Position the plant so the crown is at the soil surface for proper airflow.
Propagating Variegated String of Pearls
Stem cuttings are the primary method for propagating Variegated String of Pearls. Take healthy stem cuttings, four to six inches long, from a mature plant. Remove pearls from the bottom one to two inches to expose nodes where roots form. Allow cut ends to dry and callus for a day or two before planting to prevent rot.
Once callused, place cuttings on top of well-draining succulent soil or insert shallowly, ensuring exposed nodes make good contact. Maintain light soil moisture through misting or light watering, and provide bright, indirect light. Roots typically form within three to five weeks, after which new plants can be cared for as established specimens.
Common Problems
Variegated String of Pearls can face common issues. If the plant loses variegation and appears greener, it often indicates insufficient light. Move the plant to a brighter spot with more indirect sunlight to restore its colors. Mushy or rotting pearls and stems indicate overwatering and potential root rot. Allow the soil to dry completely; if severe, unpot, inspect, and trim rotted roots before repotting in fresh, dry succulent mix.
Shriveled or dry pearls usually point to underwatering or severe root rot preventing water absorption. Check soil moisture; if dry, water thoroughly. If moist but pearls shrivel, root rot may be the issue. Pests like mealybugs, aphids, and spider mites can also affect the plant. Signs include sticky residue, distorted growth, or visible pests. Manage infestations by isolating the plant and treating with insecticidal soap or neem oil.
