Water: Originating from damp habitats, marsh willowherb prefers consistent moisture and is moderately drought-tolerant, thriving with weekly watering. As an herbaceous perennial, it experiences dormancy, reducing water needs and adapting to seasonal precipitation changes.

Fertilize: For optimal growth, marsh willowherb requires balanced nutrition fertilizer every 4-6 weeks during the growing season. Light applications prevent nutrient overload, with reduced frequency in winter. Avoid contact with foliage, follow instructions, and conduct regular soil testing for effective nutrient management.

Pruning: Marsh willowherb is a perennial found in wetlands, with slender stems and pink to purple flowers. Prune in early to late spring by removing dead stems and thinning older growth to promote new shoots, enhance vigor, and manage its spread in gardens.

Propagation: Marsh willowherb, part of the Onagraceae family, propagates through cuttings for genetic consistency. Use healthy, non-flowering cuttings, dip in rooting hormone, and plant in well-draining soil. Maintain moisture and indirect light until roots develop, then transplant to a permanent location.
