Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water consistently 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 Arenaria species generally prefer drier soil.
Pruning is generally minimal for Arenaria densissima. After flowering, you can lightly trim back any straggly stems to maintain a neat, compact shape.
This also helps to encourage denser growth and prevent the plant from becoming leggy.
Propagation is best achieved through division of established clumps in spring. Carefully separate young plants with roots attached.
Alternatively, cuttings can be taken in late spring or early summer and rooted in a well-draining medium.
Repot Arenaria densissima every 2-3 years, or when the plant becomes root-bound. Use a fast-draining potting mix, such as a cactus or succulent blend, with added grit.
Repot in spring before active growth begins to minimize transplant shock.
