Duckweed is one of the most underrated aquatic plants in the world. Despite being a very small plant, it has a plethora of benefits which makes it a must-have in any aquatic environment. It can be used to maintain water quality, as a food source for aquatic animals, and even as a fertilizer for other plants. But before you can reap the rewards of this resourceful plant, you need to learn how to harvest duckweed.

Harvesting duckweed is not difficult, but it does require a bit of knowledge and practice. In this article, we’ll explain everything you need to know about harvesting duckweed, from the best harvesting methods to the most suitable tools and equipment. So, let’s get started.

Choose an Appropriate Pond or Lake

The first step in harvesting duckweed is to choose the right pond or lake. Duckweed grows best in ponds and lakes with a lot of light and nutrient-rich water. Look for ponds or lakes that have plenty of sunlight, plenty of vegetation, and a large population of fish. These ponds and lakes will provide the ideal environment for duckweed to thrive.

When selecting a pond or lake, make sure to check for any signs of pollution. Polluted waters will reduce the chances of successful duckweed growth and can even harm the health of the aquatic environment. If you’re not sure if the pond or lake is safe, consult with a local water quality expert.

Choose the Right Tools and Equipment

Once you’ve chosen a suitable pond or lake, you’ll need to gather the right tools and equipment for harvesting duckweed. Some tools and equipment you’ll need include a net, buckets, and gloves. The net should be large enough to scoop up the duckweed, and the buckets should be deep enough to hold the duckweed without spilling.

You should also wear gloves when harvesting duckweed to protect your hands from any sharp edges. Gloves also help to prevent any disease-causing organisms from entering your body.

Harvest at the Right Time

Timing is critical when it comes to harvesting duckweed. The best time to harvest duckweed is in the early morning when the water is still and the duckweed is still moist. This will make it easier to scoop up the duckweed without damaging the plant.

Once you’ve harvested the duckweed, you should immediately transfer it to a bucket of water to keep it fresh. You can also add some fertilizer to the water to help the duckweed to thrive.

Separate the Duckweed from Other Aquatic Plants

Once you’ve harvested the duckweed, you’ll need to separate it from other aquatic plants. Duckweed is easily confused with other aquatic plants, so it’s important to be careful when harvesting it. Make sure to check for any signs of disease or pests before transferring the duckweed to its new environment.

To separate the duckweed from other aquatic plants, you can use a sieve or a strainer. Place the aquatic plants in the sieve or strainer and carefully shake it to separate the duckweed. You can also use your hands to pick out any unwanted aquatic plants.

Clean and Store the Duckweed

Once you’ve harvested and separated the duckweed, you’ll need to clean it and store it properly. To clean the duckweed, rinse it off in cold water to remove any dirt or debris. You can also add some bleach to the water to kill any disease-causing organisms.

Once the duckweed is clean, you can store it in a container filled with water and a few drops of hydrogen peroxide. This will help to prevent any mold or bacteria from growing on the duckweed. Make sure to change the water in the container every few days to keep the duckweed fresh.


Harvesting duckweed is a simple process that anyone with a bit of knowledge and practice can master. All you need is the right pond or lake, the right tools and equipment, and the right timing. Once you’ve harvested and stored the duckweed, you can enjoy its many benefits, from providing a food source for aquatic animals to maintaining water quality.
