Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water moderately when the top layer of soil feels dry to the touch. Avoid waterlogging, as Arenaria balearica prefers well-drained conditions.
Reduce watering in winter, allowing the soil to dry out more between applications to prevent root rot.
Prune lightly after flowering to maintain a compact shape and encourage bushier growth. Deadhead spent blooms to improve appearance. Heavy pruning is generally not required, as it naturally forms a dense mat.
Propagate by division in spring or early autumn. Carefully separate small clumps of the plant, ensuring each piece has roots attached.
Alternatively, take cuttings in late spring or early summer, rooting them in a moist, well-drained medium.
Repot every 2-3 years or when the plant becomes pot-bound. Use a well-draining compost mix, such as a gritty loam or a specialized succulent/cactus mix. Repot in spring before active growth begins.
