Watering, pruning, propagation, and repotting details from plant data
Water sparingly during the growing season (spring and autumn), allowing the soil to dry out completely between waterings. Reduce watering significantly in winter to prevent rot, especially when the plant is dormant.
Overwatering is the most common cause of failure.
Pruning is generally not required for Gibbaeum album. Remove any dead or dried leaves to maintain a tidy appearance and prevent potential disease. If the plant becomes leggy, it may indicate insufficient light.
Propagate by offsets or stem cuttings. Allow cuttings to dry and callus for a few days before planting in well-draining succulent soil. Offsets can be carefully separated and planted directly.
This is best done in spring.
Repot every 2-3 years or when the plant outgrows its container, preferably in spring. Use a gritty, fast-draining potting mix designed for succulents or cacti.
Ensure the new pot has drainage holes to prevent waterlogging.
