Common Florida Pond Weeds  – Weed Control for Lakes and Ponds

With more than 7,700 ponds and lakes dotted throughout the state, Florida is no stranger to inland aquatic life. Unfortunately, not all of that life is great for fish, people, or property values. That’s why many people and companies invest in weed control for lakes.

But how bad can a weed problem really be? You might be surprised. These ecosystems support a wide range of plants that can choke the life out of surrounding flora and pose a challenge for boaters or fishermen. Let’s take a look at some of the most common you might see throughout the state.

Water Hyacinth — An invasive species from South America, these free-floating perennial plants can grow as tall as three feet. Many people don’t realize hyacinth is a problem because it has attractive flowers that might seem like a benefit at first. But these invaders are highly aggressive and can easily cover your pond in thick mats that don’t leave enough oxygen for fish.

Hydrilla — Another perennial, these dense colonies can form in water that’s more than 20 feet deep. They’re able to reproduce a variety of ways, allowing them to easily outcompete and kill off other plants. Plus, they hinder water navigation because of how thick they grow at the water’s surface.

Giant Duckweed — Contrary to its name, giant duckweed is relatively small. That doesn’t mean it isn’t a threat! It grows densely, and can quickly cover a pond’s surface. Once that happens, your fish are in danger.

Filamentous Algae — One of the most visually unpleasant pond pests, these sheets of wet plant matter should be argument enough to exercise weed control for lakes. In addition to taking up resources that other plants need, they serve as breeding grounds for a wide range of bugs and worms that you probably don’t want crawling around in your water.
