The String of Pearls plant (Senecio rowleyanus) is one of the most popular trailing succulents, known for its unique bead-like leaves and cascading vines. This eye-catching houseplant is perfect for hanging baskets, windowsills, and modern plant decor. In this guide, we’ll explore how to care for a String of Pearls plant, how to propagate it, common problems, and styling ideas to enhance your home.
What Is a String-of-Pearls Plant?
The String of Pearls succulent is a fast-growing, drought-tolerant houseplant native to southwest Africa. It belongs to the daisy family (Asteraceae) and gets its name from its small, round, pearl-like leaves. These leaves store water and help the plant survive dry conditions, making it an ideal indoor plant for beginners and busy plant parents.
Best Lighting for String of Pearls
The String of Pearls plant thrives in bright, indirect sunlight. Direct morning sun is beneficial, but too much intense afternoon sun can burn its delicate leaves.
Light tips:
- Place near a south or west-facing window
- Use sheer curtains to filter intense sunlight
- Consider using a grow light in low-light spaces
Avoid keeping your plant in dark corners or full shade, as it may grow leggy and lose its compact shape.
How to Water a String of Pearls Plant
Watering is critical for healthy String of Pearls care. These succulents are sensitive to overwatering.
Watering schedule:
- Water every 2–3 weeks during the growing season (spring/summer)
- Reduce watering to once a month in fall and winter
- Use the “soak and dry” method: water thoroughly and let the soil dry out completely
Signs of trouble:
- Shriveled pearls = underwatering
- Mushy stems = overwatering or root rot
Always plant in a container with drainage holes, and avoid letting the plant sit in water.
Best Soil for String of Pearls
Use a well-draining cactus or succulent potting mix. You can also make your own by combining:
- 2 parts regular potting soil
- 1 part perlite or pumice
- 1 part coarse sand
This soil mix prevents water from pooling around the roots and reduces the risk of rot.
Ideal Temperature and Humidity
The String of Pearls plant prefers warm, dry conditions:
- Ideal temperature: 70–80°F (21–27°C)
- Minimum temperature: 50°F (10°C)
- Humidity: Low to moderate
Avoid placing it near heaters, air vents, or cold drafts. It is not frost-tolerant and should be brought indoors during the winter.
How to Fertilize a String of Pearls
Fertilize your String of Pearls every 4–6 weeks during the growing season with a diluted succulent fertilizer. Avoid over-fertilizing, which can damage the plant or encourage weak growth.
Tip: Use a balanced liquid fertilizer at half-strength. Don’t fertilize in winter.
How to Propagate String of Pearls
Propagating String of Pearls is simple and fun! The easiest way is by using stem cuttings.
Propagation steps:
- Cut a 4–6 inch stem from a healthy vine
- Let the cut end callous over for 1–2 days
- Place the cutting on top of moist, succulent soil or in water
- Roots will form in 2–3 weeks
You can also lay stems flat on soil, pressing them gently so the nodes touch the surface.
Repotting and Pruning Tips
Repot your String of Pearls plant every 1–2 years in the spring. Use fresh, succulent soil and a slightly larger pot. Choose terracotta pots for better breathability.
Pruning tips:
- Trim leggy or damaged vines to encourage fullness
- Pinch growing tips to promote bushier growth
- Use trimmings for propagation
Best Companion Plants and Styling Pairings
Create eye-catching indoor arrangements by pairing your String of Pearls with other plants that thrive in similar conditions:
Great Companions:
- Burro’s Tail (Sedum morganianum): Another trailing succulent with thick, overlapping leaves.
- Hoya species: Wax plants with thick leaves that like similar light and water.
- Echeveria: Rosette succulents that provide a structural contrast to the pearls.
- Crassula ovata (Jade Plant): The Upright form complements the cascading pearls.
- Cactus varieties: For a bold desert-style look.
These combinations work well visually and make watering and lighting easier since they all enjoy similar care.
Common Myths and Misconceptions
Myth 1: “String of Pearls doesn’t need any sunlight.”
Truth: While it tolerates low light for short periods, it needs bright, indirect light to thrive and maintain its iconic plump leaves.
Myth 2: “You should mist String of Pearls.”
Truth: As a succulent, it dislikes humidity. Misting increases the risk of rot and should be avoided.
Myth 3: “You can bottom-water it like other houseplants.”
Truth: It’s better to top-water thoroughly and let it drain completely. Bottom watering may not reach all roots due to the plant’s shallow root system.
Myth 4: “More pearls mean a healthier plant.”
Truth: Density is one factor, but true health is determined by color, firmness, and overall growth—not just volume.
Common Problems and How to Fix Them
| Problem | Cause | Solution |
|---|---|---|
| Shriveled Pearls | Underwatering | Water thoroughly, check soil moisture |
| Mushy Stems | Overwatering/root rot | Cut damaged parts, let dry, repot if needed |
| Leggy Growth | Low light | Move to a brighter location |
| Yellow Leaves | Too much sun or water | Adjust light exposure and watering |
| Pests (mealybugs, aphids) | Poor airflow or infested soil | Use insecticidal soap or neem oil |

- Hanging baskets: Let vines trail down elegantly
- Macrame hangers: Add a boho-chic touch

Mix with companion plants like Burro’s Tail, String of Dolphins, or Echeveria for a stunning succulent arrangement.
