What is hornwort?
Hornleaf, also called Ceratophyllum Demersum, is a native aquatic plant species whose purpose is to release oxygen to the water in the pond. Because hornwort is an aquatic plant that grows very quickly, your pond will immediately benefit from the oxygen release the plant gives to the water!
What types of hornwort are there?
There are 2 types of hornwort, namely coarse hornwort and fine hornwort. There is no difference between these 2 pond plants in terms of function. The only difference is in the appearance of the aquatic plant. Coarse hornwort, as the name suggests, has broader and coarser stems than fine hornwort.
How do you plant hornwort?
Hornleaf does not need to be planted in a special way, all you need to do is to lay down the stem of hornleaf in the water. The oxygen plant will then float in the pond water where the plant will continue to grow. But of course you can also choose to plant the water plant, you do this at the bottom of the pond at a depth of up to 120 centimeters.
How fast does hornwort grow?
Hornleaf is a fast-growing aquatic plant, the pond plant can grow up to 10 centimeters per day! At most, a stem of hornwort can grow 3 meters long. Often they do not grow longer because the stem then breaks off, the stems then grow on separately. This makes the aquatic plant ideal if you want a full overgrown pond quickly!
How much hornwort is ideal for the pond?
Pond specialist Simon van der Velde recommends placing a minimum of 6 stems of hornwort per square meter in the pond and a maximum of 12 stems per square meter. This will ensure a perfect balance of oxygen plants in your pond!

Simon's vision is to let nature do its work in your pond. No need to buy all kinds of measuring equipment and water improvers. If the fish are swimming nicely and the plants are growing well, then the water in the pond is of good quality. With a good planting plan and the right approach, you can save a lot of money and maintenance, and ensure a clear, biologically balanced pond that becomes more beautiful every year.
