Pruning: Seawrack features submerged, ribbon-like leaves and flourishes in marine settings. Prune in early to late spring to remove dead leaves, promoting growth and water circulation. Avoid over-pruning to prevent stress, as proper care enhances oxygenation and reduces disease risks.

Propagation: Seawrack is an aquatic perennial that propagates through rhizome division. To successfully grow new plants, separate substantial rhizome pieces with multiple shoots. When replanting, use loose, nutrient-rich sediment. Initially shielding cuttings from currents helps ensure establishment.
