Duckweed is one of the most common aquatic plants, found in many ponds and lakes throughout the world. It is a floating plant that grows in a wide range of water conditions. Duckweed is easy to grow and can be used for a variety of purposes, from keeping aquariums clean to providing food for fish. Growing duckweed from seeds can be a rewarding experience, and it can also be an easy way to start a new pond or aquarium. Read on to learn more about growing duckweed from seeds.

Choose Your Seeds

The first step in growing duckweed from seeds is to choose the right type of seeds. Duckweed is available in many varieties, and each of these varieties has different characteristics. Some varieties are more suited to warm climates while others are better adapted to cold climates. When choosing your seeds, it is important to consider the climate and water conditions of your area. Once you have chosen the right variety, you can purchase the seeds from a local garden center or online retailer.

Prepare the Seeds

Once you have purchased your duckweed seeds, you will need to prepare them for planting. Begin by soaking the seeds in warm water for 12-24 hours. This will help to soften the outer layer of the seed, making it easier for the seed to germinate. After the seeds have been soaked, you will need to remove any debris or contaminants from the surface of the seed. This can be done by gently brushing the seed with a soft brush or by gently rubbing it between your fingers.

Planting the Seeds

Once your seeds have been prepared, you are ready to plant them. The ideal way to plant duckweed seeds is to scatter them on the surface of the water. The seeds can then be left to float around until they settle on the bottom. It is important to ensure that the water is shallow enough for the duckweed to get the sunlight that it needs to grow. If the water is too deep, the duckweed will not be able to get enough sunlight and will not be able to grow.

Maintain the Duckweed

Once the duckweed has been planted, you will need to maintain it. Regular pruning is important to keep the duckweed from becoming overgrown and taking over the pond or aquarium. You will also need to check the pH level of the water and adjust it if necessary. Duckweed prefers slightly acidic water, so you may need to add some pH stabilizing chemicals to the water if the pH is too high or too low.

Fertilize the Duckweed

In order to ensure that your duckweed is growing well, you will need to fertilize it. Duckweed is a fast-growing plant and will need regular fertilization in order to reach its full potential. The best way to fertilize duckweed is to use a liquid fertilizer that is specifically formulated for aquatic plants. You should apply the fertilizer every two weeks, or as directed by the fertilizer’s instructions.

Harvest the Duckweed

Once your duckweed has grown to a suitable size, you can begin to harvest it. The best way to harvest duckweed is to scoop it off the surface of the water with a net. Be sure to remove any debris or contaminants from the duckweed before consuming it. Duckweed can be eaten raw, cooked, or dried and stored for later use.


Growing duckweed from seeds is a rewarding experience, and it can be a great way to start a new pond or aquarium. Duckweed is an easy plant to grow and can provide many benefits, from keeping aquariums clean to providing food for fish. With the right care and maintenance, you can grow a healthy crop of duckweed from seeds in no time.
