How to care for String of Pearls (Senecio rowleyanus)
Quick facts
- Water roughly every 14 days
- Light: Bright, indirect light
Overview
Senecio rowleyanus, commonly known as String of Pearls, is a unique and charming succulent native to the arid regions of southwestern Africa. Its trailing stems are adorned with pea-like, spherical leaves that store water, giving it a distinctive appearance. This plant is a wonderful choice for hanging baskets or shelves, adding a whimsical touch to any indoor space.
Watering
Water thoroughly only when the soil is completely dry to the touch, typically every 2-4 weeks depending on conditions. Overwatering is the most common cause of root rot; ensure good drainage. Signs of underwatering include shriveling or flattening pearls.
Light
String of Pearls thrives in bright, indirect light. It can tolerate some direct morning sun, but intense afternoon sun can scorch its delicate leaves. Place it near an east-facing window or a few feet away from a south or west-facing window.
Soil & potting
Use a well-draining succulent or cactus potting mix. You can amend standard potting soil with perlite or pumice to improve aeration and drainage, which is crucial for preventing root rot in this plant.
Fertilizing
Feed your String of Pearls sparingly during the growing season (spring and summer) with a diluted succulent fertilizer. Avoid fertilizing in fall and winter when the plant's growth slows down.
Seasonal care
During spring and summer, provide consistent watering and light feeding. In fall and winter, reduce watering significantly and stop fertilizing, as the plant enters a period of dormancy. Protect from cold drafts.
Common problems
Overwatering leads to root rot, causing yellowing and mushy stems. Mealybugs can also be an issue; inspect regularly and treat with neem oil or insecticidal soap. Underwatering causes pearls to shrivel and flatten.
