Fighting duckweed with natural pond plants

Duckweed can quickly cover your pond water and disrupt the natural balance, but with the right oxygen plants, it can be easily controlled. In fact, oxygen plants absorb nutrients that duckweed needs, reducing its chance to grow. By adding suitable oxygen plants to your pond, you also help regulate CO₂ levels and keep the water clear and healthy.

Fighting duckweed with natural pond plants

One of the most effective ways to combat duckweed is by using the right aquatic plants. Plants such as hornwort and elodea densa provide extra oxygen and compete with duckweed for nutrients, reducing its chance to grow. These plants not only ensure healthy water quality, but also give the pond a beautiful natural look.

Organic pond products for natural balance

In addition to aquatic plants , the use of biological pond products such as BACTA CLEAR and INSTA CLEAN can help restore biological balance in the pond. These products stimulate beneficial bacteria that break down waste products in the water, which limits the growth of duckweed. By using these products, you can improve water quality in a safe and environmentally friendly way.

Creating shaded areas for less sunlight

Duckweed grows fastest in sunny spots. By creating shaded areas in your pond, such as with floating plants like water soldier, you can limit the amount of sunlight reaching the water's surface. This reduces the growth of duckweed and contributes to a natural balance in the pond.

Manual duckweed removal

Manual removal can also be effective in reducing the problem quickly. A fine-mesh net or scoop net can help remove large amounts of duckweed. You can combine this with natural solutions such as organic pond products and oxygen plants to restore balance to the pond and limit the emergence of new duckweed.

Maintenance with natural products for long-lasting results

A healthy pond requires regular maintenance with natural products. By adding products like BACTA CLEAR at regular intervals, you help keep the water clean and clear without chemicals. At vdvelde.com, you'll find everything you need to keep your pond healthy and free of duckweed.

Duckweed control package

Duckweed gets its nutrients primarily from the soil. To combat it, you must address the nutrient source and balance the pond.

Cleaning up soil silt → Less nutrients in the soil means less opportunity for duckweed to grow.
Adding additional oxygen plants → These compete with duckweed and absorb nutrients, giving duckweed less room to grow.

With our duckweed control package you tackle duckweed in a simple and natural way. Everything you need is included! Rather put it together yourself? The products are also available separately.
