These guides come from the permanent Plant Library rather than current stock. A QR label therefore continues to work after the plant is sold, dispatched or no longer available.

String of Pearls • Variegated Form Care Guide
Care overview
Lay several nodes onto an airy, free-draining medium. Avoid high humidity and overwatering; shallow pots with airflow work well.
Light
Bright, indirect light to morning sun
Watering
Allow the upper half of the mix to dry, then water thoroughly. Do not leave the roots wet or keep the plant completely dry for extended periods.
Humidity
Low to moderate (40–55%)
Temperature
18–28°C
Feeding and fertiliser
Feed lightly every 6–8 weeks during spring and summer with a dilute cactus or succulent fertiliser. Do not feed unrooted propagations.
Potting mix
50% potting mix, 30% perlite, 20% coarse pumice
Propagation
Node-bearing stem cuttings laid onto the medium
Support
Ideal for hanging baskets or trailing displays. Trellising can trap moisture and increase rot risk.
Mature size
Mature indoor size varies with the species, support, light and root space. Expect gradual development into a fuller specimen rather than a fixed final size.
Semi-hydro suitability
Suitability depends on the plant, root condition and the chosen semi-hydro system.
Dormancy and winter growth
No true dormancy is normally required indoors. Growth may slow during the darker UK winter, so reduce watering and feeding in line with the plant's actual growth rate.
About this plant
String of Pearls (Curio rowleyanus) is held in the Snip & Sprout permanent collection and propagated in small batches when suitable parent growth is available.
Mealybugs
Likely cause
Mealybugs may hide in leaf joints, stems, crevices and around the root zone.
What to do
Inspect regularly, isolate affected plants and identify whether the infestation is above or below the growing medium before treating.
Pale variegated areas browning
Likely cause
White or very pale tissue with little chlorophyll can be more vulnerable to scorch and visible damage, but browning can also result from water stress, root problems, salt build-up and other growing conditions.
What to do
Provide suitable bright light without exposing sensitive pale tissue to excessive direct sun, keep watering consistent and maintain healthy roots. Diagnose repeated browning rather than assuming all damage is unavoidable.
Root or stem rot
Likely cause
Prolonged wet conditions, poor drainage and low root-zone oxygen can damage roots and favour root-rotting organisms.
What to do
Use a suitably free-draining medium, provide adequate light and allow the medium to dry to the degree appropriate for the species before watering again.
Stretched growth
Likely cause
Weak, elongated growth is commonly associated with insufficient light.
What to do
Increase light gradually to a level suitable for the species. Existing stretched growth will not become compact again.
Does String of Pearls go dormant in winter?
No true dormancy is normally required indoors. Growth may slow during the darker UK winter, so reduce watering and feeding in line with the plant's actual growth rate.
How large can String of Pearls grow indoors?
Mature indoor size varies with the species, support, light and root space. Expect gradual development into a fuller specimen rather than a fixed final size.
What is the most important care point for String of Pearls?
Lay several nodes onto an airy, free-draining medium. Avoid high humidity and overwatering; shallow pots with airflow work well.
