How to Propagate String of Pearls: A Step-by-Step Guide

String of Pearls (Senecio rowleyanus, now reclassified as Curio rowleyanus) is one of the most visually striking succulents you can grow — and one of the most rewarding to propagate. Those cascading strands of perfect spherical leaves are surprisingly easy to multiply once you understand what this plant needs. Here's how to do it successfully.

How String of Pearls Propagates

String of Pearls propagates primarily through stem cuttings. Unlike many succulents, it doesn't propagate well from individual leaves — you need a section of stem with multiple pearls attached. The good news is that cuttings root quickly and readily when given the right conditions.

What You'll Need

• A healthy String of Pearls with long, full strands
• Clean, sharp scissors (sterilized)
• Well-draining succulent or cactus potting mix
• A shallow pot or tray with drainage holes
• Optional: rooting hormone powder

Step 1: Take Your Cuttings

Select healthy strands and cut sections 3–4 inches long using clean scissors. You can take multiple cuttings from a single strand — this is a great way to tidy up a leggy plant while propagating at the same time. Remove the pearls from the bottom inch of each cutting to expose the bare stem, which is where roots will emerge.

Step 2: Let the Cuttings Callous

Set the cuttings aside in a dry, shaded spot for a few hours to allow the cut ends to callous. This step reduces the risk of rot when the stem contacts soil. Unlike thicker succulents, String of Pearls doesn't need a long callousing period — a few hours is usually sufficient.

Step 3: Plant the Cuttings

There are two effective approaches:

Laying on Soil (Recommended)

Lay the cuttings horizontally on the surface of lightly moistened succulent mix, pressing the bare stem sections gently into the soil. This maximizes the number of contact points between stem and soil, encouraging roots to form along the entire length of the cutting. Pin down with a hairpin or bent wire if needed to keep the stem in contact with the soil.

Upright in Soil

Insert the bare end of the cutting 1 inch into the soil upright. This works well but produces roots only at the base rather than along the full stem.

Step 4: Provide the Right Environment

• Light: Bright, indirect light. String of Pearls needs good light to root and grow, but direct sun can scorch fresh cuttings.
• Temperature: 65–80°F (18–27°C). Avoid cold drafts and temperatures below 50°F.
• Watering: Mist lightly every few days until roots establish, then transition to a normal succulent watering schedule (water thoroughly, then allow to dry completely before watering again).
• Humidity: Low to moderate. String of Pearls prefers dry air — avoid propagation domes, which can trap too much moisture and cause rot.

Step 5: Wait for Roots and New Growth

Roots typically form within 2–3 weeks. You'll know the cutting has rooted when you see new pearl growth emerging or feel resistance when gently tugging the stem. Once established, resume normal care.

Common String of Pearls Propagation Mistakes

• Using individual leaves: Unlike many succulents, String of Pearls does not reliably propagate from single pearls. Always use stem cuttings.
• Overwatering: This is the most common cause of failure. String of Pearls is highly susceptible to rot. Water sparingly and ensure excellent drainage.
• Using a propagation dome: Trapped humidity encourages rot in this species. Skip the dome and propagate in open air.
• Too little light: Insufficient light leads to weak, sparse growth. Bright, indirect light is essential.
• Skipping the callous step: Even a few hours of callousing significantly reduces rot risk. Don't skip it.

Tips for a Fuller Plant

For the most lush, cascading result, plant multiple cuttings together in the same pot. String of Pearls looks best when densely planted, and propagating several strands at once gives you a full, established-looking plant much faster than a single cutting.

With the right conditions and a light hand with water, String of Pearls is a joy to propagate — and a stunning addition to any succulent collection.
