Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Sea Wormwood prefers well-drained soil and is drought-tolerant once established. Water moderately during dry periods, especially in the first year. Avoid waterlogging, as this can lead to root rot.
Allow the soil to dry out slightly between waterings for optimal health.
Prune Sea Wormwood in early spring before new growth emerges to maintain a compact shape and remove any winter damage.
Deadheading spent flower stalks in late summer can also prevent self-seeding and encourage a tidier appearance. Light trimming can be done throughout the growing season.
Sea Wormwood is easily propagated by seed sown in spring or by division of established clumps in early spring. Cuttings can also be taken from semi-hardwood in summer.
Ensure good drainage for seeds and cuttings to prevent rot.
Repotting is rarely necessary for Sea Wormwood, as it thrives in well-drained conditions and can tolerate being slightly root-bound. If container-grown plants become pot-bound, repot in spring into a slightly larger pot with fresh, well-draining potting mix.
