Aquatic plants are plants, generally shrubs, which have specifically specialized organs that make them survive completely submerged in water, or with all the root system constantly submerged in water. Many aquatic plants are also widespread in nature, even in Italy, and do not fear the winter cold; others, on the other hand, are of tropical origin, therefore they do not tolerate frost.
The first type of plant always lives in water, with leaves and stems floating underwater or on the surface of the water; the second type instead has only the foot in the water, while the rest of the plant develops like any other shrub, in the air.
Aquatic plants have particular root systems and also particular leaves or stems, modified so as not to excessively absorb water and to make the most of all the oxygen they can find.
How to plant aquatic plants
When purchasing an aquatic plant, it is important to know if it will live, as water lilies do, for example, completely submerged, or if it prefers to be buried on the edges of a pond or pond; in this way we can position it in the best place for its development.
Therefore, once the position has been identified, we will plant our plant directly in the ground, also in the common garden soil, covering the substrate with a good thickness of sand, so as to prevent the earth from becoming cloudy in the water.
If our pond is still empty, or we can empty it, we can therefore place plants inside it, on the seabed, while if it is already full we will place the plants on the banks, or we will plant them in containers; in this way we will place the container in the place we prefer or even we can put tropical plants in the pond during the summer, and we will move them to a protected place during the winter.
We use plastic containers, without holes, to be filled with sand-covered earth; the container is then fixed to the bottom, or weighed down by pebbles so that it does not float.
Some plants can be placed directly in the water, since the root system does not need to be buried; in this case we can use special grilled baskets, which allow us in any case not to have to "free" the plant in the pond, but to be able to place it in the place we prefer.
