What is Duckweed?

Duckweed is a small aquatic plant that belongs to the Lemnaceae family. It is also known as water lens or water velvet. It is a floating plant that grows rapidly in still water, and can spread quickly to form a floating mat. It is also a highly nutritious food source for animals and birds, and it can be used to treat wastewater. Duckweed can be grown in a variety of conditions, including ponds, lakes, or even in tanks or barrels. It is also a great alternative for those looking for a sustainable food source.

Benefits of Duckweed

Duckweed has many benefits. It is a great food source for ducks and other waterfowl, as well as other wildlife. It can also help to improve water quality by absorbing excess nutrients from the water, which can reduce algae growth and improve clarity. Duckweed can also be used as a fertilizer, as it contains high amounts of nitrogen and phosphorus. Additionally, duckweed can be used as a natural water filter, as it is effective at removing heavy metals and other pollutants from water.

Preparing the Area for Growing Duckweed

Before you can begin growing duckweed, you need to make sure that the area where you plan to grow it is prepared properly. You will need to ensure that the water is clean and free of pollutants and debris. Additionally, you should make sure that the water is not too shallow, as duckweed needs at least 6 inches of water depth to thrive. You should also make sure that the water is not too warm, as duckweed prefers cooler temperatures.

Planting Duckweed

Once the area is prepared, the next step is to plant the duckweed. You can buy duckweed from a garden center or online. You can also collect duckweed from ponds or lakes, but make sure to check for any pollutants before bringing it into your tank. Once you have the duckweed, you can either directly plant it into the water or put it into a mesh bag and submerge it into the water. The mesh bag will help to keep the duckweed from floating away.

Maintaining Duckweed

Once the duckweed is planted, it will begin to spread quickly. To keep it from taking over the tank, you will need to thin out the duckweed regularly. This can be done by manually removing the excess duckweed or by using a skimmer net. Additionally, you will need to make sure that the water is kept clean and free of debris, as this will help to keep the duckweed from becoming overcrowded.

Fertilizing Duckweed

Duckweed is a fast-growing plant and will need to be fertilized regularly to ensure that it continues to thrive. You can use a liquid fertilizer specifically designed for aquatic plants, or you can use a slow-release fertilizer. When using a liquid fertilizer, you should make sure to follow the instructions carefully, as too much fertilizer can be harmful to the duckweed. Additionally, if you are using a slow-release fertilizer, you should make sure to place it away from the duckweed, as the fertilizer may damage the plants.

Harvesting Duckweed

Once the duckweed has grown to a desirable size, you can begin to harvest it. To do this, you can simply use a skimmer net to scoop out the duckweed. Make sure to remove all of the excess water before transferring the duckweed to a container, as the duckweed needs to remain moist. You can then use the duckweed as feed for animals or birds, or you can use it as a fertilizer for your garden.


Producing duckweed can be a great way to provide a sustainable food source for animals or to help improve water quality. It can be grown in a variety of conditions, but it is important to make sure that the area is properly prepared and that the water is kept clean. Additionally, it is important to fertilize the duckweed regularly and to thin it out when necessary. When done correctly, duckweed can be a great addition to any water feature.
