Lance-leaf water plantain (Alisma lanceolatum)

Lance-leaf water plantain

Also known as: Lance-leaved water plantain

Commonly known as lance-leaf water plantain, Alisma lanceolatum is no friend to rice crops since it often grows as a noxious weed in rice paddies. This water-loving wildflower looks similar to Plantago-aquatica, but its leaves are more narrow and its flowers are lilac-colored instead of pink. You're likely to see this plant at the edge of ponds and streams, and it is particularly fond of canals.

Water: Originating from marshy environments, lance-leaf water plantain thrives in moisture-rich conditions with moderate drought tolerance. It needs weekly watering for hydration and is best planted in areas that replicate its wetland habitat, ensuring moist, well-drained soil for optimal growth.

Fertilize: For lance-leaf water plantain, use balanced fertilizers with equal NPK ratios during active growth, switching to high phosphorus before blooming. Fertilize monthly at half-strength, reducing during dormancy. Avoid over-fertilization to prevent root burn. Adjust fertilization seasonally, applying evenly and avoiding direct contact with foliage and roots.

Pruning: Lance-leaf water plantain is an aquatic perennial with broad, lance-shaped leaves and star-like flowers. Prune dead or damaged foliage in early spring and maintain through late spring. Regularly remove yellowing leaves to enhance water quality and promote blooming, using clean, sharp tools to prevent stress and disease.

Propagation: Lance-leaf water plantain is an aquatic perennial thriving in wetland conditions, propagating mainly through division during its dormant phase. Successful propagation requires each division to include part of the root system, with careful handling and timely replanting ensuring rapid recovery and establishment of new specimens.
