How to Keep String of Pearls Alive: Expert Care Tips

By Michael Chen · January 23, 2026

To keep a string of pearls (Curio rowleyanus) alive, provide bright indirect light, well-draining soil, and water only when the soil is completely dry. Avoid overwatering, maintain temperatures between 70°F and 80°F (21–27°C), and use a succulent-appropriate potting mix to prevent root rot.

Understanding String of Pearls Care Basics

The string of pearls (Curio rowleyanus) is a unique trailing succulent prized for its bead-like leaves and cascading growth habit. Native to arid regions of Southwest Africa, it thrives in conditions that mimic its natural habitat: low humidity, infrequent watering, and plenty of sunlight.

Key Challenges in Keeping String of Pearls Alive

Overwatering leading to root rot
Insufficient light causing leggy growth
Poor drainage or compacted soil
Exposure to cold drafts or temperatures below 50°F (10°C)
Pests such as mealybugs and spider mites

Optimal Light Conditions for Healthy Growth

String of pearls requires bright, indirect sunlight for at least 6 hours daily. Direct afternoon sun can scorch the foliage, while too little light leads to stretched stems and sparse foliage.

Ideal Placement by Season

Spring & Summer: East or south-facing window with sheer curtains
Fall & Winter: Move closer to windows; supplement with grow lights if needed

Watering Techniques That Prevent Root Rot

This succulent stores water in its spherical leaves and needs minimal irrigation. Water deeply but only when the soil is fully dry—typically every 2–3 weeks in warm months and once a month during winter dormancy.

Signs of Improper Watering

Underwatering: Wrinkled, shriveled beads
Overwatering: Yellowing, mushy stems and dropping pearls

Season	Water Frequency	Soil Moisture Level	Light Duration (hrs/day)
Spring	Every 2 weeks	Dry 1 inch deep	6–8
Summer	Every 2–3 weeks	Dry completely	6–8
Fall	Every 3–4 weeks	Dry completely	5–6
Winter	Once monthly	Dry completely, top 2 inches	4–5

The data shows that watering frequency should decrease significantly in cooler months, aligning with reduced evaporation and plant dormancy. Maintaining dry soil between waterings is critical year-round to avoid fungal issues and root decay.

Choosing the Right Soil and Pot

Use a fast-draining succulent or cactus mix amended with perlite or pumice (up to 50%) to enhance aeration. Terracotta pots are ideal due to their porous nature, which helps wick away excess moisture.

Pot Selection Checklist

At least one drainage hole
Terracotta or unglazed ceramic material
Size no more than 2 inches wider than root ball

Fertilizing and Seasonal Maintenance

Fertilize sparingly—once per month during spring and summer with a balanced, diluted liquid fertilizer (e.g., 10-10-10 NPK at half strength). Do not fertilize in fall and winter.

Pruning Tips

Trim leggy stems to encourage bushier growth
Use cuttings for propagation in fresh succulent mix
Remove dead or diseased stems immediately

Common Pests and Diseases

Mealybugs and spider mites are common pests. Inspect regularly under leaves and along stems. Treat infestations early using insecticidal soap or neem oil applied weekly for 3 weeks.

Symptoms and Solutions

White cottony patches: Mealybugs — dab with alcohol-soaked cotton swab
Fine webbing: Spider mites — increase humidity slightly and spray with neem oil
Mushy base: Root rot — repot immediately in dry, fresh mix after trimming roots

Frequently Asked Questions About String of Pearls Care

Why are my string of pearls turning yellow?

Yellowing pearls typically indicate overwatering or poor drainage. Ensure the soil dries completely between waterings and check that your pot has adequate drainage holes. Replace soggy soil immediately to prevent root rot.

How often should I water my string of pearls?

Water every 2–3 weeks in growing seasons (spring and summer) and reduce to once a month in winter. Always confirm the soil is fully dry before watering again.

Can string of pearls survive in low light?

No, prolonged low light causes etiolation—stretching and leaf loss. While it tolerates some shade, it needs bright indirect light for at least 5–6 hours daily to thrive.

Is string of pearls toxic to pets?

Yes, string of pearls is toxic to cats and dogs if ingested. It contains compounds that may cause vomiting, diarrhea, and depression. Keep out of reach of pets and children.

How do I propagate string of pearls?

Take 3–4 inch stem cuttings, lay them on top of moist succulent soil, and secure lightly with pins. Roots will form within 2–3 weeks. Keep in bright, indirect light and mist occasionally until established.
