Rainwater: a precious resource for the vegetable garden


There is no need to say that water is a fundamental resource for the garden: for plants, water is a primary source of life and in hot weather it is important to irrigate with the right doses and quantities.

To wet the crops you can use the water network: it is obvious the convenience of opening a tap from which you immediately get how much water you need. However, anyone who has a vegetable garden or garden has convenience in recovering and using rainwater as well.

The recovery of rainwater is ecological, because it avoids the waste of a precious resource, but also economic, because it saves on the bill. And not only that: as we will see very often it also has agronomic advantages.

How to recover rainwater

To recover a good amount of rainwater it is worthwhile exploit the roofs. They are surfaces that intercept the rain and generally convey it, through the gutters, into a pipe. It is therefore sufficient to connect this pipe to a tank to have a conspicuous quantity of water recovered at each precipitation.

obviously the greater the roof area, the greater the potential for water recovery.

On a smaller scale, those who cultivate a vegetable garden can use any small sheds, such as the shed for storing tools, to which it is easy to add a gutter and a pipe to carry rainwater into the container.

This is also a pe wayr obtain water when the garden is in a field without connection to public water.

Containers for water recovery

Once the collection method has been established, it is important to have a container large enough to hold the amount of water that we think will be used for our crops.

Here you have to be provident: obviously water accumulates with the rains, but it serves the garden when it is not raining, so the cistern will be the reserve in which to store and must be large enough to be able to withstand periods of prolonged drought, especially when it is the only water source.

Who has a land with an annex building has convenience to study ua permanent solution, which you associate with the gutter a tank of adequate sizeis.

Among the various possible tanks, underground and not, an interesting and very suitable solution for agricultural use is that of the Eco Tank soft tanks, which have the advantage of being foldable when they are not in use, which is no small feat given that a large capacity tank has an important footprint.

Advantages of rainwater

Recovering water resources from the rains as mentioned in the introduction is first of all useful on an ecological level: water is a precious resource not to be wasted and accumulating what the climate naturally grants is a good way to avoid waste.

In addition to this, and obviously in addition to the savings on the bill, the recovery of rainwater for garden irrigation is positive for two reasons:

  • Allows you to irrigate at room temperature. The water network with underground pipes during the summer supplies water that is much colder than the outside temperature, this can cause thermal shocks to the plants. The water in the tanks instead remains to decant and is obviously at room temperature.
  • It does not contain chlorine. Tap water is often made drinkable with disinfectants such as chlorine and is very calcareous, so irrigation with stored rainwater is better.
