Care guide for Greek Valerian

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

Water

Keep the soil consistently moist, especially during dry periods. Water thoroughly when the top inch of soil feels dry. Avoid waterlogging, as this can lead to root rot.

In hotter climates or during active growth, more frequent watering may be necessary.

Pruning

Deadhead spent flowers to encourage more blooms and maintain a tidy appearance. Cut back the plant in late fall or early spring to remove dead or damaged foliage and to promote vigorous new growth.

This also helps prevent self-seeding if not desired.

Propagation

Propagate by division in early spring or fall. Carefully separate the root ball into smaller sections, ensuring each section has roots and shoots. Replant immediately in prepared soil.

It can also be propagated by seed, sown in fall or early spring.

Repotting

Repot container-grown plants every 2-3 years, or when they become root-bound. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.

Repotting is best done in early spring before new growth begins.
