Soil Type

Water: Marsh rosemary thrives in saline wetlands, preferring consistently moist but not waterlogged soil. Watering should occur weekly to mimic its coastal environment. As an herbaceous perennial, marsh rosemary retains water in its fleshy leaves, aiding its survival during high tide and increased soil salinity.

Fertilize: To promote marsh rosemary's growth and flowering, use balanced fertilizers and seasonal high-phosphorus options twice a year. Apply gently to avoid root disturbance, water afterward for absorption, and adjust feeding frequency from spring to fall. Follow manufacturer's guidelines for specific amounts to prevent over-fertilization.

Pruning: Marsh rosemary thrives with proper late winter to early spring pruning during its dormant phase. Remove old and damaged stems for new growth and ensure clean tools to prevent disease. Pruning enhances air circulation, reduces mold risks, and promotes a compact, healthy appearance in marsh rosemary.

Propagation: Marsh rosemary flourishes in salt marshes and alkaline soils, where reproduction aids survival. To propagate marsh rosemary, division is recommended—separating a mature plant into sections with their own roots, ensuring high success rates when planted in a suitable substrate that mimics marsh rosemary's natural habitat.
