Algae & Water Weed Guide Pages

This Water Weed Guide is designed to help pond owners identify and manage aquatic weeds and algae in their lakes and ponds. Management of most aquatic plant species depends on properly identifying the desirable or nuisance plant. Our aquatic weed control product recommendations are based on over thirty years of field experience with the do-it-yourselfer in mind. These are general recommendations that typically work when used according to the product label. Our biologists may choose to use other products and solutions when on site as the water chemistry of each pond is unique. We also carry products to rid your property of nuisance geese.

The following pages picture common aquatic weeds throughout the country. Place your weed in a clear glass jar with water and compare it to the pictures. Pay careful attention to the leaves. Keep in mind prior to implementing any control method that plants are a necessary and beneficial component of healthy pond ecosystems. Nevertheless, plants can cause problems and control measures to eliminate or reduce overabundance are available.

To get started, identify the group of aquatic weeds to which you feel your problem weed belongs and work through the examples until you find it. Refer to the aquatic weed zone map if unsure which group of aquatic weeds your issue belongs to.
