Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Arenaria acaulis prefers consistently moist soil, especially during its active growth period. Allow the top centimeter of soil to dry out between waterings. Avoid waterlogging, as this can lead to root rot.
Reduce watering significantly during winter dormancy to prevent over-saturation.
Pruning is minimal for Arenaria acaulis. Lightly trim back any dead or straggly growth after flowering to maintain a tidy appearance. This also encourages denser foliage.
Avoid heavy pruning, as it can disrupt the plant's natural low-growing habit.
Propagate Arenaria acaulis by division in early spring or autumn. Carefully separate clumps, ensuring each section has roots and shoots. Alternatively, sow seeds in autumn or early spring.
Cuttings can also be taken in late spring or early summer.
Repot Arenaria acaulis every 2-3 years, or when the plant becomes pot-bound. This is best done in early spring before new growth begins.
Use a well-draining potting mix, such as a cactus or succulent blend, or add perlite to a standard potting mix.
