The ‘String of Arrows’ (Ceropegia woodii ‘String of Arrows’ or Ceropegia linearis ssp. woodii ‘String of Arrows’) is a popular trailing succulent. Native to South Africa, it features elongated, arrow-shaped leaves with attractive veining that cascade from hanging baskets. Its drought-tolerant nature and straightforward care make it a favored houseplant.
Caring for Your String of Arrows
Light Needs
The String of Arrows thrives in bright, indirect light. Place your plant near a window that receives ample ambient light but is shielded from harsh, direct afternoon sun. While it tolerates some direct morning sun, excessive intense sunlight can cause the leaves to turn pink or reddish, or lead to scorching.
Watering Practices
Watering is crucial for String of Arrows, as these succulent-like plants store water in their leaves and stems. Overwatering is a common issue, leading to root rot and yellow, mushy leaves. Use the “soak and dry” method: water thoroughly until drainage, then allow the soil to dry completely before the next watering. This means watering every one to two weeks during the active growing season (spring/summer), and reducing frequency to once or twice a month in fall/winter dormancy.
Ideal Soil Mix
A well-draining soil mix prevents waterlogging and root rot for String of Arrows. A specialized succulent or cactus mix, often containing perlite or sand, provides enhanced aeration and drainage. If using a standard potting mix, amend it with 50% to 70% mineral grit like coarse sand, pumice, or perlite to improve drainage. Ensure the pot has drainage holes to allow excess water to escape.
Temperature and Humidity
The String of Arrows prefers average indoor temperatures, ranging between 60°F and 80°F (15-27°C). It is not frost-hardy; avoid temperatures consistently below 50°F (10°C), bringing plants indoors during colder months. Average household humidity levels are sufficient, as this semi-succulent is tolerant of dry air. Misting is not necessary and can cause problems.
Fertilizing Your Plant
The String of Arrows has minimal fertilizer requirements. During its active growing season (spring and summer), apply a diluted, balanced liquid houseplant fertilizer once a month or every two months. The plant can also thrive without regular fertilization if repotted periodically with fresh soil. Avoid fertilizing in fall and winter when growth slows, as this can lead to nutrient buildup and harm the plant.
Propagating String of Arrows
Propagating String of Arrows is achieved through stem cuttings. Take cuttings with at least three to four nodes (points where leaves emerge). Remove leaves from the bottom half, ensuring at least two nodes will be submerged in water or in contact with soil.
Water propagation
For water propagation, place cuttings in a small glass jar with room temperature water, keeping leaves above the water line. Change the water every few days to keep it fresh and prevent algae. Roots begin to develop within a couple of weeks; once they are at least half an inch long, transplant cuttings into soil.
Soil propagation
Alternatively, root cuttings directly in soil. Fill a small pot with a well-draining succulent mix and moisten it slightly. Lay stem cuttings on the soil surface, ensuring nodes contact the moist substrate; gently bury them or use bent paperclips to hold them down. Keep the soil lightly moist (not soaking wet) and provide bright, indirect light to encourage rooting, with new growth signaling establishment.
Addressing Common String of Arrows Issues
If leaves appear mushy or turn yellow, it indicates overwatering, which can lead to root rot. To resolve this, allow the soil to dry out completely between waterings and ensure proper drainage. Conversely, wrinkled or shriveled leaves signal underwatering, indicating the plant needs a thorough soak.
Lack of growth or leggy stems with increased space between leaves points to insufficient light. Move the plant to a brighter, indirect light location to promote denser, healthier growth. String of Arrows can be susceptible to common houseplant pests like mealybugs or spider mites. Regular inspection helps early detection; address infestations promptly with appropriate, non-toxic treatments like neem oil to prevent widespread damage.
