Keep Your Pond Healthy with Pond Weed Killer from Harrietta Hills

Vegetation removal and pond weed killer is a key component of many pond maintenance plans. Often, the easiest way to keep weeds under control is by simply using herbicides. That being said, herbicides need time to work, so ponds with a high water replacement rate often find herbicides to be ineffective. In this case, a pond owner has a few options for pond control and pond weed killer.


Manual cutting is the best way to get rid of pond weeds when herbicides are not an option. Although using a weed cutter is more labor-intensive, it can be very effective. To begin this method, you will need waders (depending on the depth of your pond), a weed cutter, and rakes. Depending on the size of your pond, you may be able to cut the weeds from the banks. However, in most cases, you are best off putting on a pair of waders and cutting from inside the pond. Most weed cutters have a very long handle with a long, serrated cutting edge, and although they are generally safe to use, as with any sharp tool, it is important to mention that improper handling can be dangerous.

Tips for Using Your Pond Weed Killer

When using a weed cutter as a pond weed killer, the very first thing that you need to do is assess the size and depth of your pond, and ask yourself a few questions. Can you reach all of the areas in your pond that you want cut from the bank? If not, do you know how deep your pond is? Will waders be sufficient? If so, it is extremely important to check the depth in front of you as you walk. Some ponds have surprisingly deep holes. If waders won’t work, consider a weed rake like the EasyPro Weed Rake that has a long rope, allowing you to throw the rake and drag it back, pulling up weeds in the process.


Before you begin cutting, make sure that all cords (such as any cords necessary for aerators) are out of your way. Nicking one of those could turn into a nasty shock for you! Then, once you begin cutting the weeds, it is important to start near the outflow of your pond. If you start at the head, you will find that you stir up the sediment, clouding the water and making it extremely difficult to see the weeds that you are trying to cut. As you work, cut the weeds as close to the bottom as you can get to minimize regrowth. If you have a screen at the outflow point of your pond, it is important to clean it frequently throughout the process so that the water will continue to flow through. Once the weeds have been cut, you will want to remove them from your pond. If they are left in the water, they will decompose. Not only does this create a foul odor, it also can exacerbate your issue by adding a lot of nutrients to your water, which helps weeds and algae to grow back much faster. As the weeds collect at the bottom end of your pond, feel free to pull them out with a rake. A landscaping rake will work in most cases, but a long-handled weed rake may be the preferred method.

Maintaining Your Pond

As you continue this maintenance of your pond, it is also important to remember that although this mechanical method of pond weed killer will significantly slow the growth of pond weeds, it will not completely stop it. This process will need to be completed at least once a year. Taking care of it in the spring/early summer can make your job easier since the weeds won’t be as big or as abundant as they will be later in the year!
