Mosquito Fern

Azolla caroliniana

Also Known As - Carolina Mosquitofern
The mosquito fern (Azolla caroliniana) is a small free-floating flowering aquatic fern native to tropical and subtropical regions. It is generally found in quiet, still water such as in stagnant ponds, ponds, lakes, and even rice fields. It is easily recognizable by its dark green or red color and by its ability to grow in a thick mat across the surface of bodies of water. The mosquito fern produces tiny flowers and helps to reduce mosquito populations by consuming the larvae. The fern is an important food source for many water birds, amphibians, and fish.

watering

For the mosquito fern (Azolla caroliniana), it is best to water twice a week with an inch of water each time. Additionally, it is helpful to mist the fern daily to keep its delicate leaves from drying out.

sunlight

Mosquito Fern (Azolla caroliniana) requires plenty of direct sunlight to grow and thrive. It has been shown to do best when exposed to 10-12 hours of bright sunlight each day. However, if planted in an area with too much direct sunlight, it is prone to drying out and wilting. As such, if planted outdoors, it's recommended to site it in a partially shaded area that receives a few hours of direct sunlight each day combined with some indirect light.

pruning

Mosquito Fern (Azolla caroliniana) should be pruned regularly and heavily. Pruning should occur once a month in the spring and summer months, and once every 2 months in the fall and winter. It is important to remove any dead or dying leaves as part of the pruning process. Using sharp, clean scissors or pruners, cut the Mosquito Fern back to half its height every time it is pruned. This will help keep the plant healthy and promote new growth.
