Care guide for Greek Gromwell

Watering, pruning, propagation, and repotting details from plant data

Water

Water Greek Gromwell regularly during its active growing season, ensuring the soil dries slightly between waterings. Reduce watering significantly in winter to prevent root rot.

Aim for consistent moisture but avoid waterlogged conditions. Proper drainage is crucial for this plant's health.

Pruning

Prune Lithodora zahnii after flowering to maintain its shape and encourage bushier growth. Remove dead or faded blooms and trim back any leggy stems.

Light pruning can also be done in early spring before new growth begins.

Propagation

Propagate Lithodora zahnii from semi-hardwood cuttings taken in summer. Insert cuttings into a well-draining medium and keep them moist and warm. Rooting typically occurs within a few weeks.

You can also try layering in spring.

Repotting

Repot Lithodora zahnii every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix, ideally with added grit. Choose a pot one size larger than the current one.

Repot in spring before the active growing season begins.
