String of pearls (string of beads) care

Light

String of pearls needs sun on the leaves, not just bright ambient room light. 4-6 hours of bright light, with some direct sun. A south or east-facing window is ideal; insufficient light produces sparse strands and shrivelled pearls. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water string of pearls when the soil is completely dry, every 2-3 weeks. Succulent-style plants store water in stem and leaf tissue — they'd rather be slightly thirsty than slightly soggy, and the most common way to kill one is to water it on a fixed weekly calendar instead of by feel. Water deeply and let the soil dry fully between drinks. Shrivelled pearls signal thirst; mushy pearls signal overwatering.

Soil and pot

String of pearls grows best in gritty cactus or succulent mix. Coarse cactus mix or 1:1 potting compost and perlite. A shallow pot suits the shallow roots. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

String of pearls sits happiest at around 30-50% humidity and 18-24°C (65-75°F). Dry household air is ideal. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed string of pearls sparingly. Quarter-strength cactus feed every 6-8 weeks during the growing season only. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on string of pearls in the Growli community. Where a problem matches one of our diagnostic guides, click through for the full step-by-step recovery plan written for string of pearls specifically.

• Shrivelled pearls — Underwatering; soak thoroughly.
• Mushy pearls — Overwatering or root rot — let dry out fully.
• Bald top of pot with strands trailing only — Lay strands on the soil surface so they root and refill the centre.
• Leggy thin strands — Insufficient light; move closer to a window.

Companion plants

String of pearls pairs well with String of hearts, Hoya, and Jade plant. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.

Propagation

Lay a strand of pearls on moist mix in a shallow tray; roots form at every node within 3-4 weeks. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

String of pearls is toxic to pets. Treat string of pearls as toxic to cats and dogs. It is not on the ASPCA's formal toxic-plant list, but the ASPCA's succulent-safety guidance says that if ingested it causes stomach upset — predominantly vomiting — and lethargy; the irritant sap can also inflame skin and eyes on contact. The exact toxic compound is unconfirmed (suspected alkaloids), so keep strands out of reach and call your vet or ASPCA Poison Control (888-426-4435) if a pet chews it. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
