String of pearls (Curio rowleyanus) is a charming succulent known for its distinctive, bead-like leaves that cascade beautifully in hanging baskets. Loved by both beginners and plant collectors, this attractive houseplant is low-maintenance and thrives in most indoor spaces, bringing a unique touch of greenery to your home.
Light Requirements
String of pearls love lots of bright, indirect sunlight. Place them near an east or west-facing window where they get filtered light. Harsh, direct midday sun may scorch their leaves, while too little light can make them leggy. In apartments, a spot close to a window with sheer curtains works best for happy, lush growth.
Watering Schedule
Let the top inch of soil dry completely between waterings—typically every 2–3 weeks. Overwatering causes mushy, yellow pearls, while underwatering will shrivel them. Signs of overwatering include soggy soil and translucent leaves; crispy, shriveled beads mean they need a drink. Humidifiers aren’t necessary for string of pearls.
Humidity & Temperature
Ideal temperature is between 18–24°C (65–75°F). String of pearls dislike cold drafts or temperatures below 10°C (50°F). Avoid placing them near air conditioners or heaters. They’re not fussy about humidity and generally do well in normal indoor conditions.
Soil & Potting
Use a well-draining cactus or succulent soil mix. Good drainage is a must to prevent root rot. Repot only when the plant outgrows its pot (every 2–3 years), and always choose a pot with drainage holes.
Fertilizing
Fertilizing isn’t a must, but a diluted succulent fertilizer once in spring and once in summer can give your string of pearls a boost. Avoid fertilizing in fall or winter when growth slows down.
Common Problems & Solutions
Yellowing leaves often mean too much water; cut back and let soil dry out. Brown, crispy beads indicate underwatering or too much sun; move to less intense light and water when soil dries. Watch for pests like aphids or mealybugs; if spotted, rinse gently or wipe with insecticidal soap.
Extra Tips
Let long strings trail in a hanging basket, or style on shelves for a dramatic effect. Companion plants like string of hearts or burro’s tail make great visual pairings. Fun fact: String of pearls can bloom tiny, cinnamon-scented white flowers in the right conditions!
