Pinnate mosquito fern
Also known as: Mosquito fern
Pinnate mosquito fern (Azolla pinnata) is a water plant that spreads rapidly on still water. In countries such as New Zealand, it is classed as invasive because it suppresses the growth of native species. But it is also a potentially useful species in removing environmental pollutants. The living and dead tissue of the plant can help to absorb dyes, and harmful chemicals from wastewater.

Water: Thriving in humid environments, pinnate mosquito fern prefers high humidity and regular watering, needing moisture weekly for optimal growth. Typically grown as an aquatic plant in outdoor ponds or water gardens, it aids in water purification by absorbing nutrients and reducing algae growth.
Fertilize: For healthy growth, pinnate mosquito fern requires balanced nutrition, benefiting from high-nitrogen fertilizers during peak growth. Apply diluted fertilizer biweekly, reducing to monthly in cooler seasons. Use high nitrogen monthly in the growing season, adjusting amounts for size. Protect waterways from runoff for optimal health.
Pruning: Pinnate mosquito fern is a floating aquatic fern with feather-like fronds. Pruning should occur in early to late spring, trimming overgrown or damaged fronds to improve growth and water circulation while reducing fungal disease risk. Use clean, sharp tools to minimize stress and damage.
Propagation: A delicate aquatic fern, pinnate mosquito fern thrives in water gardens and ponds, enhancing ecosystems with its nitrogen-fixing abilities. It propagates through spores, which need careful handling when distributed on the water surface. Stable warmth and light are essential for successful germination and growth.
