Appearance of the String of Pearls
As the name suggests, the String of Pearls plant features cylindrical or rounded bead-like leaves along trailing stems. Individual leaves measure only about 1/4-1/2 inch wide and are stacked so tightly together they appear to be on a string. The leaves can be green, blue, silver or variegated shades.
This plant has an amazing ability to cascade freely over the edges of any container, pot or hanging basket. Full mature strands can reach 3-4 feet in length making it a showstopper.
Great for People who:

Caring for the String of Pearls
String of Pearls care truly could not be simpler. Water just enough to keep the pearls plump and hydrated, about once every 2-3 weeks. Too frequent watering can cause rot. Allow the top inch of soil to dry in between waterings.
It can tolerate low humidity and withstands temperature between 60 to 85 degrees F. Just be sure not to overwater and you’ll be successful with this unique trailing plant.
Toxicity Level of the String of Pearls
All parts of this plant are toxic to pets and livestock if ingested. Symptoms can include vomiting, drooling, diarrhea and potentially organ damage in severe cases. Keep it well out of reach of curious animals.
Light Requirements for the String of Pearls
String of Pearls thrive in medium to bright indirect light. Direct sun can cause scorching.
Light Conditions | Effect on String of Pearls |

An east or west window is a great spot. Rotate occasionally for balanced growth.
Watering the String of Pearls
- Water sparingly, about every 2-3 weeks or when the pearls appear deflated and wrinkled.
- Use room temperature water and avoid soggy soil which can cause rot.
- Allow soil to become dry between waterings, this builds character.
- The pearls will become noticeably shriveled when thirsty, plumping back within hours of watering.
Fertilizing the String of Pearls
String of Pearls are quite resilient and may not even need fertilizer, especially if repotted annually. If the plant is not thriving, incorporate a diluted liquid fertilizer once every 2-3 months during spring and summer. Dilute to 1⁄4 – 1⁄2 strength.
Potting the String of Pearls
Repot annually in spring using a well-draining soil-less potting media. Gently remove from nursery pot being careful of the delicate stems. Secure the base in the new container and guide stems over the edge. Water sparingly.
Propagation of the String of Pearls
String of Pearls readily propagate from stem cuttings. Simply place a 5–6 inch cutting with 3-4 pearl beads water in a clear jar or container to allow roots to develop over 4-6 weeks. Once rooted, pot up in well-draining soil and care for as the parent plant.
Growth and Development
With its minimal needs, String of Pearls grows slowly throughout the year. Trim stems periodically to encourage bushier growth. Ensure the potting mix dries slightly between waterings. Move to indirect light if growth becomes leggy. Space looks magical adornede with full dangling strings.
Managing Pests and Diseases
Mealybugs occasionally bother String of Pearls. Check leaves for signs of fuzzy white insects. Thoroughly rinse plants and apply neem or insecticidal soap treatment. Provide good drainage, air flow and sanitize pruners between trimmings to deter any issues.
