The ponds in question range from just under an acre to several acres in size. Many of these pond plants tend to appear almost overnight with warm, sunny days fueling their growth. Rainfall washes nutrients into ponds, thus causing these "blooms" of aquatic vegetation. While having a healthy mix of several water plants in a pond is a good thing, having one or two plants taking over an entire pond, is not indicative of a healthy pond, nor is it aesthetically pleasing to the pond owner.
Some of the most commonly seen problem aquatic plants are as follows:
Any plant can turn into a nuisance and control measures may be necessary. While most aquatic plants can be controlled by applying herbicides, the application requires a joint permit from the Fish and Boat Commission and the Department of Environmental Protection. Herbicides can be a quick fix, but if applied incorrectly, they can lead to unwanted killing of aquatic species like fish and frogs. There are some non-chemical alternatives such as barley straw to prevent algae, and triploid grass carp which eat some submerged plants, although these methods too must be researched to see if they are right for your pond. A pond water test is also recommended to determine the pH levels, dissolved oxygen, and bacteria levels - all important to consider depending on what the pond is being used for. Water test kits are available through your local county Extension office.
