Duckweed (Lemna Minor)

Duckweed Lemna Minor

Lemna Minor, commonly known as Duckweed, is a fast-growing, resilient and low-maintenance floating aquatic plant. Its petite, bright green leaves add a delicate botanical look to any planted aquarium or pond. As its name implies, Duckweed is a top floating aquarium plant pick that is well-known for its rapid growth. This makes it a great addition to aquariums or ponds with a high bioload. Through its tiny root system, Duckweed happily absorbs excess nutrients and is as a great source of natural water filtration. Beyond supporting improved water quality, aquarium floaters also create a layer of coverage and extra security for a variety of aquarium and pond fish. Many fish species, such as fancy goldfish, will also enjoy snacking on Duckweed!

For a beautiful, nature-style look in your planted tank or pond, try mixing duckweed with other floating plants like Pistia stratiotes (water lettuce) or Phyllanthus fluitans (red root floaters).

What to do with excess Duckweed

Duckweed grows quickly, so it’s important to harvest and thin it regularly to prevent overgrowth and shading of submerged plants that need light to grow. When disposing of excess duckweed, please avoid releasing it into local waterways, ponds, or down your plumbing. We recommend composting it or allowing it to dry out completely before discarding. It can also be incorporated into soil mixtures! Thank you for helping protect native ecosystems.
