Water: Prostrate marshwort thrives in wet habitats, requiring high humidity and weekly watering. As a deciduous plant, it sheds leaves in dry seasons to conserve water, making it ideal for outdoor gardens in regions with ample rainfall.

Fertilize: To promote root growth and flowering in prostrate marshwort, use a high-phosphorus fertilizer quarterly, following guidelines. Reduce applications in autumn for dormancy preparation. Avoid over-fertilizing and mix the fertilizer into the topsoil around prostrate marshwort, keeping it away from foliage and stems.

Pruning: Prostrate marshwort has low-growing, vine-like stems ideal for ground cover. Prune in early to late spring to encourage growth and shape. Remove dead stems and thin crowded areas for air circulation. Regular pruning promotes healthier foliage and disease prevention; use clean, sharp tools for precise cuts.

Propagation: Prostrate marshwort thrives in moist, well-drained soil when seeds are sown directly. Fresh seeds improve germination, and pre-soaking can further enhance rates. A light soil layer on the seed bed ensures moisture for growth, while consistent watering supports healthy, vigorous plants.
