Water: Scouler's fumewort thrives in humid environments, requiring a balance of moisture and dryness. Weekly watering is ideal. As an evergreen, it grows actively during rainy seasons, reflecting its dependence on water for optimal growth.

Fertilize: For optimal growth, fertilize scouler's fumewort with balanced nutrition every 4-6 weeks during the growing season, using about 0.5 tsp per gallon of water. Water before fertilizing to avoid root burn, adjust frequency in fall, and refrain from fertilizing in winter. Wear gloves and avoid over-fertilization.

Pruning: Scouler's fumewort is a herbaceous perennial with fern-like leaves and pink to purple flowers. Prune in early to late spring to remove dead stems and leggy growth, promoting bushiness and vitality. Avoid excessive pruning to prevent stress and reduced flowering.

Propagation: To propagate scouler's fumewort, use healthy, non-flowering stem cuttings. Employ a well-draining soil mix and place them in a warm, indirect sunlight location. Rooting hormone can enhance root establishment. Keep cuttings moist, and handle fragile roots gently during transplantation.
