Duckweed is a type of aquatic plant that has been used for decades in water gardens and as a natural form of filtration for ponds and other bodies of water. Many people think that duckweed smells bad, but is this true? In this article, we'll take a look at what duckweed smells like and how it affects the environment.

What Does Duckweed Smell Like?

The short answer is that duckweed doesn't have a strong smell. Even though it is an aquatic plant, it doesn't give off any kind of strong odour. Some people may notice a faint earthy smell, but it is generally not unpleasant or overwhelming. This can be attributed to the fact that duckweed doesn't produce any volatile compounds like other plants do.

What Causes the Smell?

The smell of duckweed is actually caused by the decomposition of organic matter in the water. As duckweed grows and dies, it leaves behind decaying material, which can give off an earthy or musty smell. This is the same smell that can be noticed in ponds and other bodies of water that are full of organic material.

What Are the Benefits of Duckweed?

Duckweed is a great natural form of filtration for ponds and other bodies of water. It helps to remove pollutants, such as nitrogen and phosphorus, from the water. This helps to keep the water clean and free of harmful substances. Duckweed also helps to reduce the growth of algae, which can be a major problem in bodies of water.

How Can Duckweed Be Used?

Duckweed can be used in water gardens and ponds to help improve the water quality. It can also be used as a natural form of filtration for fish tanks and aquariums. Duckweed can also be used as a form of compost for garden plants, as it helps to provide essential nutrients.

Are There Any Negatives to Duckweed?

One of the main negatives to using duckweed is that it can be quite invasive. If it is not controlled properly, it can quickly take over a body of water. This can lead to a decrease in oxygen levels and an increase in pollutants, which can be damaging to the environment. It is important to keep an eye on duckweed growth and to take measures to control it if necessary.

What Are the Best Preventative Measures?

The best way to prevent duckweed from taking over a body of water is to limit the amount of organic material that is present in the water. This can be done by regularly cleaning up debris and dead plant matter, as well as controlling the amount of fertilizer and other pollutants that are present in the water. Additionally, regular maintenance of the pond or water garden can help to keep duckweed growth under control.


As we can see, duckweed doesn't have a strong smell and can be beneficial for water gardens and ponds. However, it can be quite invasive and should be monitored closely. By taking the necessary preventative measures and controlling the amount of organic material in the water, duckweed growth can be kept under control.
