Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water Arenaria erinacea regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter to prevent root rot.
Ensure good drainage to avoid waterlogged conditions, as this plant is susceptible to fungal issues.
Prune Arenaria erinacea after flowering to maintain its shape and encourage denser growth. Deadhead spent flowers to improve appearance and prevent self-seeding if unwanted.
Light trimming can also be done in early spring before new growth begins.
Propagate Arenaria erinacea by stem cuttings taken in late spring or early summer. Cuttings should be at least 5 cm long and placed in well-draining compost.
Alternatively, division of established clumps in spring is also effective.
Repot Arenaria erinacea every 2-3 years or when it becomes root-bound. Use a well-draining potting mix, such as a cactus or succulent blend.
Repot in spring, ensuring not to over-pot; a slightly snug pot often promotes better flowering.
