The String of Pearls, scientifically known as Senecio rowleyanus, is a captivating succulent that has gained immense popularity among indoor plant enthusiasts. Its unique pearl-like foliage and cascading growth habit make it a standout addition to any indoor garden. This String of Pearls Care Guide aims to provide comprehensive insights into nurturing this gem to its full potential.

Light Needs

String of Pearls thrives in bright, indirect light. A spot near an east or west-facing window, shielded by sheer curtains, is ideal. While it can tolerate some direct sunlight, prolonged exposure can cause the pearls to scorch. If you notice the pearls turning yellow or becoming shriveled, consider adjusting its placement.

Soil Type

For beginners, a well-draining cactus or succulent mix, like those from Miracle-Gro or Espoma, will suffice. Advanced gardeners can create a mix using one part perlite, one part sand, and two parts potting soil. This ensures optimal drainage. The plant prefers a slightly acidic to neutral pH, ranging between 6.0 and 7.5.

Watering Preferences

Being a succulent, String of Pearls requires minimal watering. Water thoroughly once the top 2 inches of soil are dry, ensuring the pot drains well. Overwatering can lead to root rot, so it’s crucial to avoid letting the plant sit in water.


Originating from arid regions of southwest Africa, this plant is accustomed to low humidity levels. Ideally, it prefers a humidity range of 40-50%. While it can tolerate average room humidity, it’s essential to ensure good air circulation to prevent fungal issues.

Ideal Temperature Range

The optimal temperature range for String of Pearls is between 70-80°F (21-27°C) during the day and slightly cooler at night. Prolonged exposure to temperatures below 50°F (10°C) can be detrimental. To maintain a consistent temperature, avoid placing the plant near radiators, heaters, or drafty windows.


Repot your String of Pearls every 2-3 years or when it becomes root-bound. If a pot size increase is necessary, choose one that’s 1-2 inches larger in diameter. This ensures the roots have ample space while preventing overwatering.


Pruning isn’t mandatory but can help maintain a neat appearance. If the strands become too long or sparse, trim them back to encourage bushier growth. Regularly removing dead or yellowing pearls can also promote overall plant health.


Propagating String of Pearls is relatively simple:

  1. Snip off a healthy strand, ensuring it has several pearls attached.
  2. Allow the cut end to callous for a day or two.
  3. Plant the calloused end into a pot with fresh soil.
  4. Water sparingly until new growth appears.

Common Pests

  • Mealybugs: Wipe with alcohol-soaked cotton swabs.
  • Spider Mites: Use a neem oil spray.
  • Aphids: Rinse with a strong water stream.
  • Scale: Manually remove and apply insecticidal soap.
  • Whiteflies: Introduce beneficial insects like ladybugs.
  • Thrips: Use yellow sticky traps.
  • Fungus Gnats: Allow the top layer of soil to dry out between watering.

Common Growth Issues

  • Shriveled Pearls: Indicates underwatering.
  • Mushy Pearls: A sign of overwatering.
  • Yellowing Pearls: Excessive sunlight exposure.
  • Sparse Growth: Inadequate light or nutrients.

Frequently Asked Questions

To encourage a denser, fuller growth in your String of Pearls (Senecio rowleyanus), consider the following steps:

  1. Pruning: Regularly trim back overly long or sparse strands. This can stimulate new growth at the base and along the strand, leading to a fuller appearance.

  2. Propagate and Plant: You can propagate cuttings from your String of Pearls. Once rooted, plant them back into the original pot to create a denser look.

  3. Adequate Light: Ensure the plant receives bright, indirect light. While they can tolerate some shade, they thrive best in well-lit conditions, which can promote denser growth.

  4. Fertilizing: During the growing season (spring and summer), feed the plant with a diluted, balanced fertilizer every 3-4 weeks. This provides essential nutrients that can promote fuller growth.

String of Pearls, being a succulent, prefers to dry out between waterings. Here’s a guideline:

  1. Check the Soil: Water when the top 1-2 inches of soil feels dry to the touch. Overwatering can lead to root rot, a common issue with this plant.

  2. Watering Frequency: Depending on the environment, this might mean watering once every 2-3 weeks. In hotter, drier climates or seasons, you might need to water more frequently.

  3. Watering Method: When you water, ensure you water thoroughly, allowing excess water to drain out of the pot. Avoid letting the plant sit in standing water.

Under optimal conditions, String of Pearls can grow relatively quickly. During its active growing season (spring and summer), it can grow several inches a month. However, its growth rate can be influenced by factors like light, water, and overall care. In brighter light (without direct sun) and with proper care, you can expect a more rapid growth rate.
