The desire to have a pond in the garden can be easily achieved using special fiberglass tanks or PVC sheets. The main feature of the pond is its uniqueness: no two are the same, as each pond is the result of the imagination of those who make and care for it.
The techniques for creating water gardens are different and each person can change them according to need. The best thing to do before you start is to take into account the cost of a garden of this type. In fact, the price of plants and materials is quite expensive and, as you can guess, requires a little care (and expense) even when finished.
The first thing to do is to prepare a project that we will carry out on a sheet of paper where a profile of the existing garden has already been drawn, foreseeing, based on the exposure of our garden, also the introduction of aquatic plants. The garden must be placed near the entrance to the house, in order to increase the value of our work. It is also important to provide a water outlet and a power socket (the most modern pumps work at 24V due to safety problems). It is advisable not to place the pond under trees or bushes as the fall of leaves, flowers and fruit would dirty our pond. Once done, you can begin work.
Draw the shape of your pond or stream on the ground, trying to reproduce the shapes of the project, with the help of a string or a rubber tube. Then proceed to the excavation by varying the depth between 40 and 80 cm. The bottom of the excavation must be covered by a thin layer of sand or finely ground earth. Spread the cloth making it adhere well to the walls and to the bottom. Delimit and then fill the spaces reserved for aquatic plants with earth. Decorate at will the inside of the pond with round pebbles, bog roots, rocks, amphorae or a layer of gravel, being careful not to use sharp materials. It is preferable to place the pump with filter a little away from the plants. Mask and cover the edge of the cloth with stones, tuff blocks or stones that can be fixed with a little cement. Finally fill the pond with water.
3. Installation using fiberglass basins
Even for rigid structures, as in the case of soft ones, we will have to do the project first (see previous page). The hole will then be formed, which must respect the shape of the basin. We will interrupt the latter by making sure that it does not come out of the hole. Once the landfill operation is completed, we recommend raising the ground, at various heights in crescendo, to position the streams and the source rock that make up the waterfall. Connect the pump with a rubber tube, which must be positioned in the basin at the source rock connection, masking it under the various elements of the waterfall. Cover the edges of the waterfall with earth or sand and proceed with the customization with the aid of small plants, flowers, pine bark, decorative stones, other rocks, etc. Check that drops or splashes of water do not come out from the components of the waterfall or from the pond below.
Before adding the totality of the water we will have to worry about the planting of aquatic plants. Inside the pond, spread a layer of 8-10 cm of earth mixed with special peat and cover it with a bit of gravel, thus preparing an excellent substrate for aquatic plants. For example, nimphees are widely used, which, flowering from May until October, are ideal for embellishing the pond. Remember that for a good flowering it is necessary that the water is calm and that the pond has a good sun exposure. If the cultivation in pot is preferred this must be the greatest possible, and it is good to renew the soil every spring. Some plants take a couple of damages before reaching their maximum beauty. Attention: if the pond is small it will be good to use dwarf varieties.
Marsh plants, in general, need a water depth between 5 and 25 cm and can usually be grown in pots. They have different flowering periods that vary from mid-March to November and are readily available on the market.
Essential for a good microsystem balance are the oxygenating plants that are distinguished in:
- floats: for example pistia, eicornia, trapanatas.
- from the bottom: for example the elodea, cabomba, valisneria, miriolium.
Such plants generally do not require pruning. However, in case of excessive development, it will be necessary to thin them.
Due to the biological cycle, algae can often form in the spring in the pond, which affects the color of the water making it greenish. In order to obviate this inesthetic problem, we recommend periodically associating anti-algae, associated with enzymes. It is also advisable not to change the water continuously, insert oxygenating plants and if possible some snails. However, there are many products on the market, specifically indicated for the elimination of algae, to make blue water, to oxygenate it or to favor the life of the fish.
Create a water garden: 6. Fauna of the pond
In the fauna of the pond in addition to the usual goldfish we can introduce the Koi carps, greedy insects and tadpole larvae. Very useful are also the Gambusie, great devourers of mosquito larvae. We remind you that it is very important not to feed the fish excessively with food during cold and very hot periods.
