Aquatic weeds are important to the shoreline ecosystem, as they provide food, shelter and breeding grounds for a variety of aquatic life and birds. Unfortunately, a proliferation of weeds can reduce the beauty and health of a beach. Cattails, pondweed, milfoil, elodea and eel-grass are among the weeds that can overtake a shoreline, promote the growth of algae, and cover your sandy beach with mud and plant debris. You can clear beach weeds manually or mechanically, as chemical treatments are either prohibited or potentially dangerous to the environment.

While important to aquatic life, too many weeds can spoil your beach.
Dig out weed roots and remove from the beach.

Use hedge clippers or garden shears to cut rooted plants such as cattails or eel grass just above the surface of the sand or waterline. Wear gloves and footwear to protect against leaf cuts. Dig out the roots with the garden fork or shovel and remove from the beach. The clippings and roots can be used as compost or mulch.

Step 2

Line the area you want to keep weed-free with a dark plastic tarpaulin. Weigh down with rocks or anchors.The plastic prevents photosynthesis from taking place, and will kill weeds, and algae, and will prevent them from taking over the beach.

Step 3

Rake the weedy area with an aquatic rake to remove weeds above and below the waterline. There are several types of aquatic rakes, all with long teeth and sharp cutting blades that remove both plants and shallow root systems. This also removes floating weeds such as milfoil and elodea. Line the area with a dark tarpaulin to stop regrowth.

Clear as many of as few weeds from your beach as needed.

Purchase a mechanical beach groomer for underwater use. These motorized groomers use weighted rollers used to disturb shallow lake beds. They crush small weeds and prevent algae, mud and seedlings from collecting on the bottom.
