Discover how to care for String of Pearls plants, encourage rare blooms, fix common issues, and where to buy them. Expert tips from a 10-year gardening pro!
Hi! I’m Ashley Scott, a gardening enthusiast with over a decade of experience nurturing succulents and houseplants. Today, I’m sharing my personal journey with the String of Pearls plant (Senecio rowleyanus)—a quirky, cascading succulent that’s stolen my heart. Whether you’re a new plant parent or a seasoned green thumb, this guide will help you master its care, solve common problems, and maybe even coax out its elusive flowers.
Why I Love String of Pearls Plants
I’ll never forget the first time I saw a String of Pearls—its delicate strands of pea-shaped leaves spilling over a hanging planter like a living necklace. I bought one on a whim, and despite a few early mishaps (overwatering, leggy stems… oops!), it’s now thriving in my sunroom. What makes this plant special? It’s low-maintenance, visually striking, and perfect for small spaces. Plus, propagating it is so rewarding—I’ve gifted cuttings to friends and even sold a few on my plant marketplace!
How to Care for String of Pearls Plants
1. Light Requirements: Bright but Gentle
String of Pearls thrives in bright, indirect light—think east- or west-facing windows. Direct afternoon sun can scorch its pearls, while low light causes leggy growth. My plant sits 2 feet from a south-facing window with sheer curtains for filtered light. Pro tip: Rotate the pot weekly for even growth!
2. Watering: Less Is More
Overwatering is the #1 killer. Let the soil dry completely between waterings. In summer, I water every 7–10 days; in winter, every 2–3 weeks. Use the “pearl test”: if they look shriveled, it’s thirsty. Mushy pearls? You’ve overdone it.
3. Soil & Potting: Fast Drainage Is Key
A gritty, well-draining mix prevents root rot. I blend 1 part cactus soil, 1 part perlite, and 1 part coarse sand. Terracotta pots are ideal—they wick away moisture.
4. Temperature & Humidity: Keep It Cozy
Aim for 65–75°F (18–24°C) and low humidity. Avoid drafty spots or steamy bathrooms.
5. Fertilizing: Feed Sparingly
During spring/summer, use a diluted succulent fertilizer (I love FoxFarm Grow Big) every 4–6 weeks. Skip fertilizing in winter.
How to Encourage String of Pearls Flowers
Yes, these plants can bloom! The fragrant, cinnamon-scented white flowers appear in summer but are rare indoors. To boost your chances:
- Maximize light: 6+ hours of bright, indirect light daily.
- Mimic dormancy: Reduce watering and keep temps cooler (50–60°F) in winter.
- Avoid stress: Stable conditions = happy plants.
My plant bloomed after I moved it outdoors to a shaded patio for the summer—try it !
Common Problems (& Solutions!)
| Issue | Symptoms | Fix |
|---|---|---|
| Overwatering | Mushy pearls, yellow stems | Let soil dry, repot in fresh mix, trim rot. |
| Underwatering | Shriveled pearls | Soak the soil, then adjust schedule. |
| Leggy Growth | Sparse stems | Move to brighter light, prune tips for bushiness. |
| Pests | Mealybugs, spider mites | Wipe with alcohol, spray neem oil, improve airflow. |
| Leaf Drop | Pearls falling off | Check for drafts, overwatering, or sudden temp changes. |
Where to Buy String of Pearls Plants
I recommend:
- Local nurseries: Check for healthy, pest-free plants.
- Online shops: Planet Desert and Etsy offer gorgeous specimens.
- Big-box stores: Lowe’s and Home Depot often carry them seasonally.
Why are they pricey? Their delicate stems make shipping tricky. A 4″ pot typically costs 15–15–25.
Are String of Pearls Plants Toxic to Pets?
Yes! All parts are toxic to cats and dogs (ASPCA confirms this). Hang them high or opt for pet-safe plants like spider plants instead.
How to Propagate String of Pearls
- Snip a 4–6″ stem.
- Remove the bottom pearls to expose nodes.
- Lay the stem on damp soil or place in water until roots form (2–4 weeks).
- Transplant and watch it grow!
I’ve rooted dozens this way—it’s foolproof.
My Top 3 String of Pearls Hacks
- Bottom watering: Reduces leaf rot. Set the pot in a tray of water for 10 minutes.
- Grow lights: Use LED lights 6″ above the plant in dark winters.
- Misting: Skip it! These desert natives hate humidity.
