The prerequisites for your garden pond soon to be home to a wealth of flora and fauna can be achieved by creating the water. With proper planning, the garden pond becomes an atmospheric oasis of tranquility, but at the same time invites you to observe and discover. Here, a water lily is opening its flowers, where a pond frog lurks inadvertent mosquitoes amidst duckweed, and on the iris leaf, a dragonfly that has just emerged from the pupa shell is waiting for its wings to dry.
The right location for the garden pond
If you want to keep a good eye on your garden pond, it is best to lay the water near the terrace or a seat. Near-natural ponds, which are supposed to attract many animals, are better off in a more secluded spot in the garden. If your plot is not flat, but rather sloping, you should plant your garden pond at its lowest point - more natural than a body of water built into a sloping slope.
The right mixture of sun and shade also plays an important role, because on the one hand the aquatic plants need a certain amount of light, so that they thrive well, on the other hand, the water should not heat too much, in order not to unnecessarily promote the growth of algae. A good guideline is five hours of sunshine per summer day. Place the water in such a way that it is shaded by larger trees or structures or an awning during the hot lunch time. Keep enough distance to the lines for electricity, gas, water or sewage, and be careful not to cover them with the water. If this does not cause problems during earthworks, then at the latest when maintenance work on the pipes is required.
Trees with flat root system (for example, birch or vinegar tree) as well as bamboos of the genus Phyllostachys and other sprawling species should not grow close to the pond. Especially the sharp, hard bamboo rhizomes can easily pierce the pond liner. Woods at the garden pond are not fundamentally a problem, as long as the wind blows the autumn leaves in the direction away from the garden pond - so the trees should grow as east of the pond, as in our latitudes west wind prevails. Incidentally, evergreen deciduous and coniferous trees are constantly renewing their foliage and can also cause a considerable nutrient input with their pollen.
Garden ponds house a rich variety of flora and fauna
Shape and size of the garden pond
The shape of a garden pond should fit the garden design. If there are curved, natural contours in the garden, the pond should also have such a shape. In architecturally designed gardens with rectangular lines, on the other hand, rectangular, circular or elliptical pools are to be preferred. Otherwise, the rule is: the bigger, the better! On the one hand, larger garden ponds usually have a more natural appearance and radiate more calm and elegance, on the other hand, an ecological balance sets in faster with larger amounts of water, so that the maintenance effort is kept within limits. Please note that you may have to obtain a building permit depending on the desired size. The regulations vary from state to state. In most cases, garden ponds are subject to approval only from 100 cubic meters or 1.5 meters deep water. Such dimensions are quickly exceeded, especially in the case of a swimming pond, so you should get in touch with the responsible building authority in good time - if there are any violations, construction freeze, disposal procedures and fines are imminent!
The right technology for the garden pond
Each pond project raises the question of whether you need a water filter or not. Basically, a garden pond that is not too small can be kept in biological equilibrium even without complex technology if the location is right and no excessive nutrient input takes place.
Garden pond with filter system: A submersible pump transports the water into the filter unit on the bank of the pond. There, algae are killed with UV light and suspended sediment. Activated carbon can also bind toxins
However, as soon as you use fish or other aquatic inhabitants, the problems start, because faeces and food residues inevitably increase the phosphate and nitrogen concentration in the garden pond, which can quickly lead to algal blooms at appropriate temperatures. In addition, lack of oxygen is often a problem when there is a lot of water heating. Therefore, you should install a filter system in case of doubt, because a retrofit is usually more complex.If you find that your pond water stays clear even without the technology, you can simply program the system to run for only a few hours a day.
Step by Step: Set up the garden pond correctly
A classically constructed garden pond consists of different zones with different water depths and step-like transitions. On the shore, the approximately 10 to 20 centimeters deep swamp zone follows, followed by the approximately 40 to 50 centimeters deep shallow water zone and in the middle is the deep water zone with 80 to 150 centimeters of water. The transitions can be made flatter and sometimes steeper depending on the taste. Tip: With a stony surface, lift the trough approximately ten centimeters deeper and fill in a correspondingly thick layer of building sand - this will prevent damage to the pond liner caused by sharp stones.

Step by Step: Creating a garden pond
First, cut the outline of your pond with short wooden pegs or simply mark it with a line of light sand
Then lift the entire pond area to the first depth. Then mark the area of the next lower pond area and lift it off. Continue until you reach the bottom of the pond. Tip: For larger ponds, it is worth borrowing a mini excavator for the earthworks
Before the pond liner is laid, you should first lay the pond recess with a special protective fleece. It protects the film from damage
When laying the film, two to three helpers are welcome, because depending on the pond size, the film can be quite heavy. It is initially laid out on the surface and then adjusted so that it rests everywhere on the ground. To do this, it must be carefully folded in some places
Then complain the pond liner with stones and lay out with gravel. So the somewhat unsightly pond liner is laminated
When the construction is complete, you can plant the pond and the shore. The finished garden pond still looks a bit bare, but once the plants have grown well, it will not be long before dragonflies and other aquatic inhabitants arrive

A garden pond with fish tilts easily: The algae multiply explosively and destroy the oxygen in the water. Here's what you can do about it.
