Tank lily (Astelia hastata)

Tank lily

Tank lily is notable for successfully adapting to living high up in trees, where it often grows in large colonies. Its long, V-shaped leaves funnel water into a reservoir where the plant saves it for dry spells. One mosquito species in New Zealand exclusively uses this plant for breeding. It also provides food for a rare bat species and many birds.

Water: Tank lily thrives in high-humidity environments, requiring weekly watering to avoid waterlogging. As an evergreen, it maintains year-round foliage and benefits from mulching to retain soil moisture, mimicking its native forest habitat. Typically grown outdoors, tank lily needs stable conditions for optimal growth.

Fertilize: Fertilize tank lily sparingly with balanced fertilizers every 4-6 weeks during the growing season, using a scant teaspoon for small pots. Avoid over-fertilization to prevent root burn. In winter, reduce frequency as growth slows, using a well-diluted solution for root safety.

Pruning: Pruning tank lily in early spring optimizes its growth cycle. Remove dead foliage and trim excess leaves for better air circulation without compromising its natural form. This practice boosts vitality, reduces disease risk, and enhances appearance, keeping tank lily vigorous and aesthetically pleasing.

Propagation: Tank lily is a hardy perennial that propagates well through division. Separate rhizomes with roots and shoots, plant in well-draining soil, and maintain consistent moisture. Provide dappled sunlight to minimize stress and promote healthy growth in young plants as they adapt.
