  • Duckweed & Watermeal Control

Duckweed & Watermeal Reduction

Duckweed and watermeal are two aquatic plants that can be found in the same body of water. They both float on top of still, calm waters where rapid growth will become a problem if they aren't eradicated quickly enough. Duckweed is an invasive species because it grows rapidly; doubling its area coverage within just days under perfect conditions. Food for ducks? Maybe not - these weeds consume all oxygen from the surface and natural sunlight by floating over other submerged vegetation, making them difficult to eradicate without proper treatment. This often leads to massive fish kills and will restrict native aquatic plants from getting appropriate amounts of sunlight.
Once the surface is covered with these weeds, in addition to making a pond or lake unsightly and not very appealing for swimming, sunlight is prevented from reaching the deeper parts of water. This can cause sub-surface plants to photosynthesize less, produce oxygen at lower levels than usual, and reduce dissolved oxygen below an acceptable level required by healthy fish populations. A strong odor will develop because organic muck loaded with excess nutrients accumulates on top of this stagnant water body that cannot circulate freely. The best way to keep your local body of water healthy is to keep these weeds under control.
Duckweed has been thought to be an effective way of cleaning up water, as it removes nitrogen and phosphorus that are harmful to the environment. Duckweeds are typically only found in ponds with septic, agricultural, or fertilizer run-off because of this ability to clean the contaminated water. They cannot remove pesticides, heavy metals, or toxins from the water. Using duckweed as a low-tech process takes time - much more than EWR's oxygenation process. Duckweed's effectiveness in removing contaminants from water can also cause problems if grown too quickly. It will cover everything else in the pond with little chance of being manually removed once overgrown.

Identifying Duckweed and Watermeal

Duckweed and watermeal are small, stemless plants that grow across the world. They're mainly found in warmer climates such as Florida, where they can be seen floating on lakes or ponds.
The duckweed and watermeal do not usually thrive in rivers unless the flow of water is reduced. However, they reproduce at an astonishing rate given enough nutrients to fuel their growth. They can cover one acre in just 45 days!
Duckweed and watermeal grow in carpet-like groups and are bright green when fully grown
Their frond or leaf ranges from the size of a pin-head to about the size of a pencil eraser
Duckweed and watermeal may have between 1 to 4 leaves
Each leaf may have 1 to 6 roots growing from its stem

Natural Removal of Duckweed & Watermeal

The best way to manage duckweed and watermeal is without chemicals, as they can be disruptive to aquatic ecosystems. In addition, many times, plants will come back with more germination from nutrient-rich muck sediments on the bottom, which means using many chemical treatments over time that may damage native wildlife populations in an area or even create dead zones where nothing lives but algae. This creates a cycle involving multiple chemical applications and dead plant biomass.

Aeration for Duckweed and Watermeal Control

It's no secret that water is necessary for all animal life, but many people do not know about their lakes and ponds are the effects of oxygen concentrations on them. Without enough of this essential element in a lake or pond, organisms will be at risk as they cannot breathe without it. With low levels near the bottom, anaerobic bacteria spread, increasing acidity to dangerous levels and releasing phosphorus and nitrogen (major fertilizers) from organic sediments into the surrounding waters. These fertilizers feed duckweed and watermeal, multiplying their quantity quickly.

Aeration systems are a great way to revitalize your pond. They bring increased dissolved oxygen levels, allowing beneficial anaerobic bacteria to thrive, which results in better water quality and natural decomposition of organic matter. This reduces duckweed and watermeal growth as well as other undesirable plant life.
Environmental Waterway Restoration has a technology to oxygenate the entire water column and sediments on the bottom. The EWR process- called Laminar Flow Aeration- provides custom solutions for providing aeration in your body of water from top to bottom, which also helps with many other environmental issues like algae blooms or fish kills.
