How to make a pond on the balcony


Those who do not have a garden are very often forced to repress certain botanical desires that require space and soil. It is therefore good news that we are giving you, that is, that you can learn how to make a pond on the balcony and the result is not bad at all. It takes a little ingenuity, plants and the right equipment, as well as time and patience to install everything and make it work. Let's see how to proceed, move by move.

Why create a pond on the balcony

Some do not like the idea of ​​tin, it is sometimes seen as a negative and even a bit dirty environment. If you stay on the surface, you can support this, but by going deeper, taking the time to get to know who populates it, both in terms of flora and fauna, you discover that the pond is a real microcosm to study, observe, admire.

A pond on the balcony is relaxing and stimulating at the same time, with exotic species and insects, so much ferment almost imperceptible at first sight but wonderful and complex. It doesn't take much to make it happen, and it will be an original variant of the usual plants that can still coexist with this new presence.

How to make a pond on the balcony: container

The container is the first thing we need to get to get started. To get a pond that makes sense, let's choose it with a diameter of at least half a meter and at least forty centimeters high. It must not have residues of harmful detergents that can compromise our entire creation. To fill it we have to use pebbles or gravel, create a layer on the bottom, and then put a lot rain water. If it is not possible to get it, then we take the one from the tap and let it settle for at least two full days, the minimum necessary for it to be suitable for the pond we are creating.

Before filling it, perhaps it is better to already arrange it in what will be its final position on our balcony, so that transport is not complex, when it will be filled with water. We try not to place it where the sun often shines, because the water could overheat, but total shade is not good in the same way, because flowering could be penalized. If the orientation of our balcony makes it possible, we put our tin container to the east so that in the morning it is in the sun and then in half shade for the rest of the day.

Create a pond on the balcony: plants

We are ready for the selection of plants that will be part of our pond. It is a bit like choosing the members of a team, it is important that they are different from each other and well combined. We must foresee the presence of oxygenating, purifying and floating, choices among those that are comfortable in our climate, so that the result is the balance of the small microcosm of which we are elected creators. Plants are responsible for cleaning the water, together with microorganisms.

To plant them we wait for the growing season, late spring or early summer, so the roots will immediately grow in the new environment. There is a formula that defines the balance for a pond: in each square meter there must be 1 floating plant with roots anchored to the ground, 3 oxygenating plants and 1 or 2 marginal plants. There are limitations to take into account also inoccupation of the pond area, so that there is no lack of oxygen. Floating plants must never cover more than half of the surface, oxygenating ones are on the bottom and must cover at least half of it. The marshes, which are filtering, should cover 20% of the surface.

Let's see some examples of plants that we can insert in our pond. The Elodea is Ceratophyllum submersum are submerged plants, important because they absorb carbon dioxide and release oxygen, keeping the water clean. They also shade with their leaves, for the benefit of fish and small insects. The elodea is also oxygenating and keeps unicellular algae away. In the pond on the balcony we can also host the dwarf water lilies that provide shade and shelter to the fish, and are also very choreographic. Among the best, the Nymphaea Pygmaea alba, rubra and helvola, the Nymphaea tetragona and the dwarf lotus flowers.

We also talked about floating plants, we can choose for this category the duckweed (Lemna minor), the water fern Azolla caroliniana, the water hyacinth eichhornia crassipes, and the Ceratophyllum demersum.

Let's move on to marsh plants, which occupy the edges of the ponds, protect from the wind and from predators that feed on fish and frogs. Among these the typha minima, the pontederia cordata, the aquatic iris, Hydrocotyle vulgaris , the Polygonum odoratum. The marshes as well as the submerged ones must stay in normal plastic pots, with a mixture of clayey earth, non-calcareous sand and organic soil, one species per pot, to prevent other plants from stealing their space. To keep mosquitoes away from our wonderful pond we must also populate it with animal species, for example classic goldfish and gambusie, freshwater fish that feed on larvae.
