How to grow string of pearls
Overview
String of pearls (Curio rowleyanus) is a trailing succulent with distinctive bead-like leaves. It is grown for its unique foliage and cascading habit, making it ideal for hanging baskets. This plant requires bright light and careful watering to thrive.
Varieties
- String of Pearls — The classic variety with small, round, bead-like leaves, widely available in Australian nurseries.
- Variegated String of Pearls — A rare form with cream and green striped leaves, offering a striking contrast in hanging baskets.
Soil Preparation
Use a well-draining cactus or succulent mix with added perlite or coarse sand. Ideal pH is 6.0–7.0. Avoid heavy clay or moisture-retentive soils; ensure the pot has drainage holes.
Growing Guide
Position string of pearls in bright, indirect light with protection from harsh afternoon sun. Use a free-draining succulent or cactus mix, and plant in a hanging basket or shallow pot to allow trailing stems. Space plants 15–20 cm apart for good air circulation. Water sparingly, allowing the soil to dry completely between waterings; reduce watering in winter. Avoid wetting the leaves to prevent rot.
Care
Feed with a diluted liquid succulent fertiliser every 4–6 weeks during spring and summer. Prune back leggy stems in early spring to encourage bushier growth. Remove any dead or shrivelled beads to maintain appearance.
Companion Planting
Pair string of pearls with other succulents like echeveria, sedum, or haworthia in a mixed hanging basket. Avoid planting with moisture-loving ferns or impatiens, which require frequent watering and can cause root rot.
Common Pests & Risks
Mealybugs are the most common pest, appearing as white cottony masses on stems and leaves; treat with neem oil or insecticidal soap. Stem rot occurs from overwatering or poor drainage; remove affected stems and reduce watering. Check regularly for spider mites in dry conditions.
Troubleshooting
Yellowing leaves: overwatering or poor drainage; let soil dry out and repot in fresh mix. Shrivelled beads: underwatering or too much direct sun; water more and move to brighter indirect light. Stems rotting: fungal infection from wet soil; remove affected parts and reduce watering. Mealybugs: white cottony spots on stems; treat with neem oil. Leaves dropping: sudden temperature change or cold draught; move to a stable spot.
