All types of vegetables and vegetables cannot live without water and must receive the right quantity, especially to obtain products that grow quickly and are excellent to consume. Otherwise they will appear fibrous and dry. In general, during the summer it is preferable to carry out the irrigation procedure at dawn, to avoid sudden changes in temperature, so that the vegetables resist better to the heat of the following hours. In the winter and autumn seasons, on the other hand, the mid-morning strip will be preferred, because it is in these hours that the water is not too cold. If the garden is made up of a soil consisting mainly of sand, it will need to be watered frequently; otherwise, one session every four days will suffice. In order not to cause suffering to the plants, especially the most delicate ones, it would be good to avoid the direct jet of water. It could also cause excessive liquid stagnation and promote the proliferation of fungi and bacteria. The most effective method is the lateral infiltration technique, which consists in administering water through the channels adjacent to the areas where the vegetables are planted; given that water is the main nutritional source in the plant world, it will be important to choose the most suitable one, checking that the streams possibly present near the ground are not polluted. Furthermore, watering with drinking water must not be carried out since it contains an excessive quantity of chlorine, harmful to the health of the plants. In addition to useful advice on the topic, the procedure for building an underground irrigation system, how to obtain drip irrigation and some other alternative methods will be indicated below.
How to build an underground irrigation system
As can be seen from the introduction, one of the best methods to irrigate the vegetable garden is that which foresees an underground plant. If you have a minimum of experience in bricolage, you can also make it at home. The first operation to be done will be to carefully observe the ground and lay a plan on graph paper in which the positioning points of the pipes and the relative irrigation connections must be indicated. Secondly, it will be necessary to inquire about the quantity and flow rate of water available and the pressure value it can sustain. After collecting this preliminary information, you will have to move on to implementation. With a rather large spade you will trace the perimeter of the plant and then dig it along the path, going to touch a depth of about 40 cm. The pipes must therefore be placed inside it and fixed with screws, clamps and fittings. At this point it will be necessary to drill the main pipe to be able to attach a retractable sprinkler, taking care to fasten it by threading to the main pipe. After putting the removed soil back in place, a general check on the functionality of the system must be carried out.
