How To Control Pondweedpondweed

A pond or lake is an asset to anyone who is fortunate enough to have one, however, invasive aquatic weeds can quickly ruin that asset if left untreated long enough. Invasive weeds can very quickly create a hostile environment in a pond, choking out desirable aquatic plants and tangling up small aquatic wildlife. These unwanted plants also make bodies of water unsightly and hinder recreational activities like swimming and finishing. One such invader is known as pondweed.

Pondweed is the broad name given to 80 or so species of aquatic plants belonging to the genus Potamogenton. One of the most common of them in this country is known as the American Pondweed. American pondweed is a perennial plant that has both floating and a few submerged leaves create a pattern where both types of leaves alternate.

The floating leaves are oval shaped and range between 4 to 7 inches long and 1 to 2 inches wide on long petioles. Leaves that are submerged in the water are few in number and are blade shaped and smaller than the ones which float about. American Pondweed bears fruit which are set on spikes that often stand above the water's surface. They are brownish to reddish in color, 2 to 3 inches long and 1/8 to 1/4 inches wide.

While a sight for sore eyes, American pondweed does provide some benefit to the ecosystem as their leaves are a food for ducks and other kinds of wildlife. However, when they are abundant in number, it can make for an ugly sight. If you have pondweed plaguing your pond or lake, Solutions Pest and Lawn has the answer to remove those invasive weeds once and for all.

How To Get Rid Of Pondweed: 3 Step Solution

If you have a smaller pond, it may be best to get rid of them manually. However, in bigger ponds or lakes where the outbreak of pondweed is a lot, physical removal may be a cumbersome task. That is why we would recommend using a chemical means of control through aquatic herbicides. The herbicides we carry can kill off pondweed quickly and conveniently if used the correct way. Here are some simple steps we have providing if you choose to go the DIY way of tackling this aquatic weed.

Step 1:  It is crucial to identify your pond weeds or lake weeds before you begin to treat. Some herbicides only work on certain plants. Make sure you know for sure that the aquatic weed you have is pondweed. Pondweed looks similar to other weeds so it can easily be confused. If you are not sure what aquatic weed you have, take a picture of it and send us a photo of the plant via email at identification@solutionsstores.com and we will respond with the correct ID of the weed and present you chemical options to best control it.

Step 2: Once you have correctly identified your weed to be pondweed and carefully analyzed the conditions of your pond or lake, you can then move on to chemical control by choosing an aquatic herbicide to tackle the invasion. At Solutions Pest and Lawn we have a wide selection of different aquatic herbicides in stock which come in both liquid or granular forms. What you choose is up to you as they both have their advantages and disadvantages. Liquid herbicides, for instance, are a great solution because they attack weed growth in shallow water on or above the ponds surface and can be spread evenly with a pump sprayer. This makes the control process efficient and convenient compared to physical removal.

Granular herbicides are also a good option in situations where are submerged as blankets under the water surface in deep areas of the pond or in ponds with flowing water. These heavier granules can be applied with a hand spreader and will sink directly onto the weed beds.

Step 3: Apply the selected herbicide to your pond or lake during ideal temperatures and following the instructions carefully on the product label of the herbicide you chose. If the pond is heavily infested with pondweed, it may be possible (depending on the herbicide chosen) to treat the pond or lake in sections and let each section be for about two weeks before treating another section. Aeration, particularly at night, for several days after treatment may help control the oxygen depletion. There is a more detailed guide on applying weeds in our Knowledge base.
