Pond Advice

For a healthy pond, we recommend adding a minimum of 2 to 5 liters hornwort per cubic meter (1000 liters of water). In addition, you can add 2 baskets of 4 plants each per square meter to the pond. This combination provides adequate oxygen production and helps keep the water balanced.

The red/brown color of hornwort is not a sign of a dead plant, but rather a natural characteristic of healthy plants grown in harmony aquatic plants. At our nursery, we work in balance with nature and do not use chemicals. If necessary, we use biological control methods. Our plants grow with the seasons, and in winter they go into dormancy, without heating the greenhouse or using artificial means such as electricity or gas.

Because we grow plants naturally, they retain their own color. elodea densa can naturally not only be green, but also take on a red/brown hue. Instead, this is a sign of a strong, healthy plant grown naturally grown.

hornwort you can simply place it loose in the pond, which is the most common way. The plant will initially float, but will eventually sink to the bottom and settle there without the need to plant it. It is also possible to plant hornwort in baskets, but this is not necessary. hornwort is an excellent oxygen plant, suitable for both small and large ponds.

hornwort Pruning is easy. Simply cut off pieces of about 10 cm and throw them back into the pond. The cut off pieces will continue to grow and multiply naturally. So the plant will just continue to grow again, but in smaller pieces, thus maintaining healthy and dense growth in your pond.

hornwort does not need a specific depth to grow well, as it can float loose in the pond and eventually move to the bottom. It grows well at almost any depth, but preferably at a depth of at least 30 cm.

Yes, hornwort is great for a pond with fish. It has a solid structure and is less attractive for fish to nibble on. In addition, hornwort grows quickly and continues to function well as an oxygen plant even when fish pull on it. It helps improve water quality by producing oxygen and absorbing excess nutrients, which is important for a healthy pond environment with fish. Because hornwort grows so fast, there is little chance that pond fish, except for the koi , will eat the plant completely.

Tip: If you have Koi's, add extra lots of oxygen plants, also with stiff structure so they are less attractive to the Koi such as water soldier. Shielding plants from the Koi's for a time until the plant is bigger is also a good idea.

hornwort (Ceratophyllum demersum ) is a dark green aquatic plant in the Hornleaf family often found in various waters. This plant, with its floating nature, can reach a length of 60 to 90 cm. A striking feature of hornwort are the lateral stems that sprout from the main stem, from which wreath-shaped, forked leaves grow. These threadlike, line-shaped leaves are rather stiff, and their forks have sharply serrated edges.

What makes the flowering process of this plant unique is that within the same plant, in the leaf axils, both male and female flowers can occur. The flowers are characterized by a 10- to 12-slip flower cover. Within this flower cover are about 20 stamens with short anthers in the male flowers, or an erect ovary with a style and stigma in the female flowers. The process of fertilization takes place under water, with pollen reaching the stigmas through the water. From this fertilization arises achenes with characteristic thorns.

The spread of hornwort in different waters can occur in different ways. Wave action can cause pieces of the plant to break off and end up elsewhere, and waterfowl can also contribute to dispersal by carrying pieces of the plant on their legs.

A special feature of the hornwort is that it prepares itself in winter for the colder months. The plants form densely foliated sprouts that sink to the bottom to overwinter. When spring arrives again, these sprouts grow into new, full-sized plants. As a result, we are dealing with a long-lived, perennial plant species.
