You should think carefully about whether you really want to care for water hyacinths in your garden pond. Although the flowers are beautiful, they rarely develop outdoors. In addition, the plant tends to overgrow and, if left uncared for, deprives the other pond inhabitants of all the oxygen.
Are water hyacinths suitable for the pond?
Water hyacinths in the garden pond need a lot of sun, warm and nutrient-rich water and high humidity. They grow quickly and can affect other plants and fish. The plants are not hardy and rarely bloom in the pond. However, they can be useful for over-fertilized ponds with a high level of algae formation.
The water hyacinth has high demands
- Bright
- Warm
- High humidity
- Nutrient-Rich Water
This is how the needs of the water hyacinth in the garden pond can be briefly summarized.
The sunnier the pond is, the better the aquatic plant will thrive. The water must contain plenty of nutrients and have a pH value between 6 and 8. The water temperatures should not fall below 15 degrees.
Riparian zones are well suited for planting. The water hyacinth forms roots that can be up to 40 centimeters long. In the middle of the pond, the water is usually too deep for the plants to anchor themselves in the ground.
The aquatic plant rarely blooms in the pond
If you are tempted to buy by the charming flowers that look very similar to spring flowers, you will be disappointed.
The aquatic plant rarely blooms in the pond. The reason for this is the humidity is too low. The water hyacinth will only bloom if it is as high as in its native South America.
This climate can hardly be created on a normal garden pond. In the aquarium you are more likely to get the water hyacinth to bloom.
Tighten water hyacinths regularly
You should never put more than three plants per two square meters in the pond if you also want to keep other plants and especially fish in it.
Water hyacinths diligently form daughter rosettes that are just as big as the mother plant within a short time.
You should take the daughter rosettes out of the water regularly. They make good humus if you dispose of them in the compost.
Water hyacinths cannot overwinter outdoors
Water hyacinths cannot be overwintered.
Tips & Tricks
There is a good reason to keep water hyacinths in the pond. Since the plants need a lot of nutrients, they are well suited to over-fertilized ponds where algae formation is very high.
