What temperatures can the aquatic plant tolerate?

Large tolerance range

The waterweed has a large temperature tolerance. It can cope with temperatures close to zero and also with values ​​above 20 ° C. It is therefore not only a suitable aquarium plant, but can also grow permanently outside in the pond. Only the Argentine waterweed is more sensitive to the cold and could freeze to death outside in winter.

Temperatures in winter

The lower limit is 4 ° C. That is why the waterweed reliably survives even harsh winters in the depths of the pond, in zones that do not freeze over. Consequently, the pond should be at least 60 cm deep. In autumn the shoots of the Waterweed brown and sink to the bottom of the pond, but in winter the plant reliably sprouts again.

Temperatures in summer

Even if the water spill survives cold water. She feels comfortable in a warm environment and only then grows visibly. It just can't get too warm for her.

• the ideal temperature range is 15-24 ° C
• The temperature should not rise continuously above 26 ° C

The warmer the water, the more luxuriant waterweed grows. This can go so far that it displaces other plants and therefore be fought got to.

Temperatures in the aquarium

The aquarium is felt all year round with warm water. That is why the waterweed remains evergreen in it. However, since it can only withstand temperatures around 28 ° C for a short time, it is less suitable for tropical aquariums.

The large plant with its long shoots can pull through the aquarium from bottom to top. It can be exposed to different temperatures in different layers of water. Even if the individual values ​​are acceptable to her, she is sensitive to these differences.

Maintain a constant temperature in the aquarium by using pool floor heating while ensuring sufficient water flow.
