Theoretically, a root can grow wherever a leaf arises. In practice, the plant does not develop roots on every node, but as required.
Sense of root formation
One of the tasks of the roots is to anchor them to the ground. Because of this, the waterweed will take root after planting. However, these are largely covered by the substrate and therefore cannot be recognized as such by us. The amount can also be described as small.
Roots can also form further up, on stems that have been washed around by water. Is the Waterweed in the aquarium, these can be clearly seen in the clear water. Presumably they serve to absorb nutrients from the water.
Tips
Waterweed plants in the pondthat are already firmly rooted in the substrate are difficult to remove fight. So calculate with the Planting their enormous urge to grow.
Propagation without roots

- a small piece of the plant is enough
- it doesn't have to have roots yet
- when planted, it will soon form roots
- can also be placed on the water
- Driving it seeks itself an opportunity to take root
Tips
