What you Should Know about Duckweed

Before we proceed with our discussion on how to get rid of duckweed, let us first have a look at what it is in the first place. Also called bayroot, this is one type of aquatic plant that can always be seen floating in shallow still fresh water, commonly in ponds at home or wetlands. It is small, leafy, and green, which is comparable to a lily pad. It grows in an environment where there is high concentration of phosphate and nitrogen.

Duckweeds can be beneficial in some ways, especially because it helps to clean the pond. It can also serve as an excellent food source for fish and microorganisms. However, in most instances, they are dreaded by many homeowners. Duckweed can grow very large and they can eat up a chunk of the pond. With this, it can make it cramped and it will affect the growth of the fish in the pond. It will lead into a significant decrease in the level of oxygen in the pond. In return, this will lessen the desirability of the water for aquatic life. This is exactly the reason why getting rid of duckweed is a common concern for many homeowners.

Prevention – this is probably the best way to get rid of duckweed. You should be proactive enough to make sure that duckweed won’t grow in the pond so that it will not have to be a problem later on. When you do this right, you do not have to use any chemical treatment, which can only harm aquatic life while killing duckweed. You should first have an understanding of why they bloomed, and from such point, you can do something to make sure that they will not be present in your pond. One of the best ways to do this is through aeration. This will be done through blowing of oxygen in the pond. In addition, another solution that can prove to be equally promising would be nutrient reduction. You have to lessen nutrient in the pond so that it won’t attract duckweed. Controlling the amount of sunlight that reaches the water, for instance, is one thing that can be considered. Also, it will help if you will not be using fertilizers anywhere near the pond.

There are also biological, controls that can prove to be equally effective when having to deal with duckweed. Adding natural predators in the pond will be a big help. Koi, goldfish, waterfowl, and grass carp can assist in controlling duckweed. They should be added, however, from the very start, as it may take quite some time before their effects can be fully evident.

You can also resort into the use of mechanical controls in order to effectively get rid of duckweed in your pond. A fine net is a simple device that can be used to remove duckweed form the pond. A mechanical skimmer can also offer the perfect solution. Although these alternatives will require more effort on your end, they can be equally effective in being able to address the problem.

Lastly, you might also want to consider the use of herbicides when it comes to dealing with duckweed. They come in different forms. For instance, there are herbicides that are meant to kill only a specific type of vegetation while there are also some that are meant to kill all. There are also some that can cause serious hazards for humans and the environment, which is why you should be careful in making a choice. Because of the hazards that they may pose, this is one of the least recommended ways to remove duckweed. The earlier mentioned alternatives are more preferred.

By now, we hope that you are already aware of how to effectively get rid of duckweed. It is not as complicated as it may seem, although it is not also a straightforward task.
