No magic recipe in sight
Fighting waterweed in an aquarium is a time-consuming undertaking, but can be mastered. The plant is cut back accordingly. In the case of waterweed in the pond, on the other hand, it looks more difficult, because here we are dealing with other dimensions and conditions.

Most of the waterweed plants could be removed from the water, but the small pieces that break off and remain in the water soon multiply into new, independent plants. This is the main challenge of the fight.
Remove waterweed manually
The spread of the waterweed can be suppressed by extensive cutting measures. The complete distance, however, is more difficult to achieve. Remove the waterweed as completely as possible with an herb rake.
So that no new water pest forest can form from small remnants, you should shade the pond and thus lower the water temperature. Warm water is a great fuel for growth. The nutrient content must also remain low. Use cautious fertilization and do not use nutrient-rich soil for planting.
Let the pond dry out
If the pond is without water, the removal of the waterweed can be more comprehensive. A frost period at this time also helps to get rid of the plague. With smaller ponds, the effort is also limited.
Chemical pesticides
In the case of chemical agents, an up-to-date check must be made every time to see whether they are approved for domestic use. But they should only be considered in exceptional cases.
- Chemistry also reaches other plants and living things in the pond
- these can become impaired or even die off
- the ecological balance is also upset
Grass carp as a waterweed eater
It is always recommended to use grass carp against waterweed in larger ponds. They eat the plants and thus contribute to their decimation. But the success is never so resounding that the waterweed regenerates again and again. Other aquatic plants that are also part of the diet of this fish species can also suffer.
Tips
Be cautious about planting waterweed. The plant grows so rampant that you can inadvertently create a problem for yourself.
