Soil Type

Water: Cow lily flourishes in moist conditions similar to its aquatic origins. It prefers wet soil and high humidity, necessitating weekly watering. Rainwater is beneficial, providing water quality and nutrients that replicate its natural ecosystem.

Fertilize: Cow lily requires balanced nutrition fertilizers, supplemented with high-phosphorus blends for flowering, monthly during the growing season and reduced in fall. Use half the dose for aquatic plants to avoid harm. Monitor leaf color for nutrient deficiencies and incorporate fertilizers gently to protect roots.

Pruning: Cow lily is an aquatic plant with floating leaves and yellow flowers, needing precise pruning in early to late spring. Cut back decayed foliage and remove flower heads after blooming to control seeding. Minimize root disturbance to promote vigorous growth. Refer to reputable sources for detailed care instructions.

Propagation: Cow lily propagates best through sowing seeds collected from aquatic habitats. Use a wet, muddy substrate and provide ample light while keeping seeds submerged. Germination may be slow, but once seedlings are established, they can be relocated to larger water bodies for continued growth.
