Hello pond fans, this is carl the landscape
guy. Thank you for the many responses regarding my video to build this natural pond. You can
check it out clicking on this link. Now some time has passed since building it and I have
made some changes on the pond I would like to show you. I’ll also show you what plants
is used for this natural pond and i will put two koi fish in today.
Last fall I mowed the shore of the pond once to have it clean for the winter and avoid
the groth of woody plants like willow and birch.It is now the end of April and all plants
have begun to grow. Here we see the area of the swamp irises. They can get up to 1m tall
and I put them in the back of the pond as a group, this way they do not obstruct the
view on the water surface and frame the pond in a natural way.
In water depths of about 60-80 cm I have set pond and water lilies. The water lily is already
showing a few leaves. The blue iris sibirica comes out too. This
plant will be more comfortable during summer when the water level is slightly lower because
its not really a water plant. It loves fresh and moist soils.
Between reeds and cotton grass, the frogs feel very comfortable.
The early flowering bogbean is already showing its buds and offers with its rhizomes projecting
into the water protection for frogs and fish. Especially the Kois like to stay here.
As you can see the fish also like to stay around the old tree root.
The animals have settled in well and apparently feel well. Altogether there are 10 fish in
this 300 m² large pond. So that the pond without filter and pump continues to work
well I feed the fish only occasionally. They can find enough food in the mud and among
the aquatic plants, just as they are supposed to as real carps. A couple of goldfish have
been fetched from the herons, but i guess that’s how it goes in a natural pond. Nevertheless,
I decided to build a heron fence in order to protect the fish population. For this I
have formed these rods with eyelets made of sturdy wire. A fishing line now runs three
times around the pond and discouraged the heron successfully already quite a while.
The design ensures a high degree of flexibility. From a few feet away the heron fence is barely
visible and it disappears visually around the natural environment.
Today I put two more young koi in the pond. For that i make sure that the water is not
too cold and the animals have enough time to get used to the new water. These kois probably
swim the first time in in natural, more turbid pond water. I hope they will be fine like
the others who have already grown a lot in a few months.
In this area there is the connection of the pond to a rainwater ditch which briefly leads
rain water. This water enables a natural way of keeping the water level up especially during
hot summers. As the rainwater ditch mostly only briefly leads a lot of water, I have
also installed this return flap. Now the water can not drain out of the pond back into the
ditch after a rainfall and the water level can be kept relatively stable even in the
summer. The flap also prevents fish or other animals from getting stuck in the pipe. Overall
I am very satisfied with this almost maintenance-free pond. If you are interested in videos about
waterstreams ponds and landscaping works, feel free to visit my channel! If there are
news about the Kois or changes made to this pond, I will gladly upload a video update.
I look forward to your comments and would appreciate a thumb up! Thanks for watching,
good luck with your projects and until next time, im carl the landscape guy.
