How to Get Rid of Weeds in Ponds & Lakes: Aquatic Weed Control Tips


Aquatic weeds can be beneficial to your pond,
but when they grow out of control, they can be more than a nuisance. Weeds like algae, duckweed, and cattails not
only hurt the look of your pond, but they can disrupt recreational activities, block
sunlight, and steal nutrients. In this video, we’ll go over some differences
in aquatic weeds and some tips on how to control them. Hi, I’m Jason with Solutions Pest and Lawn. If you’re new to us, we create these videos
to help educate people like you about DIY pest control. If you want to learn more and find the right

weeds that can invade your pond, and sometimes, a herbicide you might use for one weed might
not be effective against another. So, the first and most crucial step in controlling
aquatic weeds is properly identifying the weed. If you already know which weed you have and
want more in-depth help, please visit our website where you can find categories for
common aquatic weeds and the best weed killers to get rid of them. Along with algae, aquatic weeds can be separated
into three groups — floating weeds, submerged weeds, and emergent weeds. As their name suggests, floating weeds are
those that float and move freely on the pond’s surface. Some common floating weeds are duckweed, bladderwort,
and water hyacinth. Submerged weeds are aquatic weeds that grow
and root underwater, and will typically stay there for the majority of its life. Common submerged weeds you might see or feel
are coontails, water milfoil, or curly leaf pondweed. And emergent aquatic weeds are the ones you
see popping out of the water. They’re typically along the shoreline, but
can extend toward the middle of the pond if its shallow enough. Common emergent weeds are cattails, water
lilies, and reed grass. You need to have an understanding of which
weed or weeds you have in order to get proper control. The type of weed your pond has will determine
which product you will use and how to apply it. Don’t forget, visit our website for in-depth
guides that can help you identify and treat for specific weeds. You can even send us a picture of the weeds
in your pond at this email address and we can identify it for you and suggest treatment
options. Once you have identified the weeds, there
are some things you need to consider before you begin treatment. First, you need to know the size of the pond. Measure the pond’s surface area and the
depth. Knowing the size will help you when figuring
out your mix rates. You will also need to consider if your pond
is used for drinking, recreation, irrigation, or houses fish. Always read the label of any aquatic herbicide
because some herbicides have water use restrictions. For instance, you might have to wait several
days before you can drink treated water depending on your application rate. When it’s time to treat, we recommend using
either Diquat or Fluridone herbicides. These professional-grade aquatic herbicides
are great because they are formulated to treat many different floating, submerged, and emerged
weeds. These aren’t just used for ponds, but can
also be used to treat weeds in lakes, reservoirs, canals, and others. Just be sure to read the label to make sure
your type of body of water is listed. Diquat and Fluridone are both liquid aquatic
herbicides. We generally recommend liquid herbicides because
they can control weeds through spot and broadcast treatments, and can be spread evenly with
a pump sprayer. Follow label directions for proper mix and
usage rates. Depending on the targeted weed and the water’s
depth, you can spray the herbicide over the water along the shoreline, spot treat emerged
weeds, or broadcast spray over the water’s surface. You can also use a product called Vision pond
dye. This is non-toxic dye that is safe for animal,
human, and plant life. This will give the water a natural blue color
but also filters UV light to inhibit algae and weed growth. Follow the label directions for proper application
rate and pour at the edge of the pond. The water’s natural movement will disperse
the dye. Important things to consider: Aquatic herbicides
are most effective against active weeds. Be sure to make sure your applications during
warm, sunny days when rain is not in the immediate forecast. Consider using a fountain or another aeration
device to create an oxygen-rich environment. And most important, only treat around one
third of the water at a time, waiting fourteen days inbetween treatments. As the weeds die off, they can reduce the
amount of oxygen in the water. Kill too many weeds at once, and it can deplete
the oxygen in the water and kill the aquatic life. These are just some of the things you can
do to control and prevent aquatic weeds from invading your pond. Visit our website for in-depth guides that
