ABOUT

Azolla pinnata, commonly known as feathered mosquito fern, is a small, free-floating aquatic fern native to Asia and Africa. It thrives in subtropical climates and is often found in rice paddies, ponds, and slow-moving streams. This hydroperennial plant is known for its rapid growth and ability to fix nitrogen, making it beneficial for agricultural purposes.

DETAILS

Care Instructions
Azolla pinnata requires bright, indirect light and thrives in warm, humid conditions. It prefers temperatures around 25°C and high humidity levels. Ensure the plant is kept in waterlogged conditions, as it is an aquatic plant. Regularly check the water quality to maintain optimal growth.
Soil
Azolla pinnata does not require traditional soil as it is an aquatic plant. Instead, it thrives in water with a slightly acidic pH. Ensure the water is nutrient-rich and free from pollutants. Peat can be used to maintain the acidity of the water.
Fertilizer
Azolla pinnata generally does not require additional fertilizer as it can fix nitrogen from the atmosphere. However, if the water lacks nutrients, a balanced aquatic plant fertilizer can be used sparingly.
Repotting
Repotting is not typically necessary for Azolla pinnata as it grows freely on the water surface. However, if the plant becomes overcrowded, you can thin it out by removing excess growth and transferring it to another water body.
Propagation
Azolla pinnata propagates easily through vegetative means. Simply divide the plant and place the sections in a new water body. Ensure the new environment has similar conditions to promote healthy growth.
Pruning
Pruning is not required for Azolla pinnata. However, you can manage its growth by periodically thinning out the plant to prevent overcrowding and ensure optimal water quality.
Toxicity
Azolla pinnata is not toxic to pets or humans. It is safe to handle and can be used in various agricultural and ecological applications.
Additional
Azolla pinnata is often used in rice paddies to improve soil fertility and reduce the need for chemical fertilizers. It also provides habitat for aquatic organisms and helps control mosquito populations by covering the water surface.
