Soil Type

Water: Sweet milfoil originates from temperate regions and thrives in moderate moisture. It requires consistent weekly watering, prefers well-draining soil, and tolerates short dryness. Typically grown outdoors, sweet milfoil's growth cycle is linked to adequate rainfall and specific climate zones.

Fertilize: Sweet milfoil requires minimal fertilization, as excessive fertilizer leads to overgrowth. Apply organic fertilizer once or twice during the spring growing season. Avoid high nitrogen fertilizers, as they can negatively impact flower coloration.

Pruning: Sweet milfoil has aromatic, fern-like leaves and bright yellow flower clusters. Pruning in early to late spring fosters growth and blooms. Remove dead stems, trim spent flowers, and shape to maintain compactness, promoting air circulation and reducing disease risk for a lush display.

Propagation: Sweet milfoil thrives with well-drained soil and ample sunlight. Propagate by sowing seeds in trays, spaced evenly and lightly covered. Maintain consistent moisture and transplant sturdy seedlings, ensuring adequate space. Support growth with regular watering, mulching, and occasional feeding for robust development.

Repotting: For sweet milfoil, a bushy perennial, repot every 2-3 years in early spring to support growth. Use a slightly larger pot with drainage. Ensure well-draining soil post-repotting and avoid overwatering to promote healthy recovery and aromatic blooms.
