The simplest of the DIY irrigation techniques is certainly the one that involves the use of the classic watering can, to be preferred with the application of the onion device, which allows you to distribute the water more evenly and in the form of a drizzle. Whatever methodology is chosen, it is essential to remember that mainly the roots of the plant will be wet, thus avoiding flowers, buds and leaflets, especially if delicate. Otherwise these fragile parts could break and fall, or the proliferation of fungi and parasites will be favored, attracted by the stagnation of liquids. So that there is no waste of water due to its evaporation, it is advisable to irrigate after sunset or even better in the early hours of the day, especially when temperatures are very high. The water pressure, before being dispensed, must be rather low; for this purpose it will be useful to create small furrows adjacent to the ground where the water can flow. If the land or garden is large, a convenient and effective method is the drip method, both for open field crops and in gardens and terraces. This plant will avoid wasting water and will allow its perfect distribution on the plants. It can be purchased in all DIY and gardening stores and is very simple to assemble: the kit includes pipes, to be chosen according to the size of the area of interest, which will first be buried and then connected to the various crops through collateral pipes. secured with cable ties and fittings. Once the main tap is put into operation, the water will reach the various crops at the same time. In general, it should be borne in mind that a vegetable garden or a garden must be thoroughly irrigated at least twice a week, increasing the frequency in the summer season. Below we will explain the procedure for creating other simple but effective irrigation systems with do-it-yourself.
A simple plant of do it yourself watering is the one that makes use of the use of common plastic bottles. Before proceeding with the processing, these containers must be thoroughly cleaned with water and neutral soap, then dry them perfectly. The next step is to heat a needle or very fine tongs over a heat source, such as a stove flame. When the needle is boiling, every bottle cap will be pierced with it; alternatively, you can still use an electric drill. Once this is done, after having unscrewed the cap, the bottles will be filled with water and then positioned over the crops by overturning them and fixing them to trellises or supports by means of hooks or simple iron wire. In the cold season the amount of water will be sufficient for a week, while in the summer the bottles will be emptied and refilled even twice a day. The second type of plant, on the other hand, uses the drip irrigation technique. The material needed is an earthenware pot and saucer of the same size, silicone and coarse sandpaper. With the sandpaper you will first go to smooth the edge of the pot and also of the saucer, then removing all traces of dust. At this point, the plate will be placed on top of the pot. When the two parts match perfectly, they will be properly sealed with silicone. Above the plate, in the center, a hole will be made using a drill. Now all you have to do is place this device in the affected area and fill the pot with water. Once turned upside down, it will function as an irrigation system and will supply a constant and uniform amount of water to the soil. As for the previous system, the pot will be fixed by overturning it to a support by means of hooks or metal wire.

Another simple plant of do it yourself watering is what uses the plastic soaker pipes. The material needed is easy to find; a hose of the necessary length, a cap that fits its circumference and an electric drill will suffice. With the drill, holes will be made at a regular distance along the entire pipe, taking care that the upper ones do not coincide with those below. The cap will be attached to one end of the hose. The next operation is to dig a small groove that covers the entire perimeter of the area to be irrigated and insert the pipe into this, which will finally be connected to the main tap. After the water has been opened, it will flow through the soaker and wet the soil through the previously drilled holes, keeping the earth drained for at least forty minutes and acting specifically on the roots of the crops. Thanks to this type of system, both will also have a considerable saving of water, even up to 70%.
To create a drip irrigation system of this type, it will be necessary to place PVC pipes so that they form a square that surrounds the crop area. Every four or five meters of pipe will therefore be placed some fittings that will be used to connect the various sections. At each termination of the pipe, the corresponding manual valves, supplied with the purchase of the pipes, will be installed, so as to allow the water to flow inside them. A flexible pipe will then be connected to these valves which will bring the water from the main system. When it is necessary to irrigate, simply open the main tap and the water will be distributed in the various pipes, gushing near the roots of the plants through the valves.
In each drip system it is possible to install a timer, that is a small device capable of programming the quantity and frequency of the various irrigations. In addition to the timer, you can also think of adding a filter for purifying the water, in order to make it cleaner and therefore healthy for both the vegetable garden and the garden plants. Once this has been done, a specific water pressure reducer will be installed, which will serve to regulate the flow and strength of the supply, so as to avoid water waste and damage to plants. A flexible plastic or PVC hose must then be connected to this device, which however does not exceed eighty-ninety meters in overall length, because at these measurements the water pressure drops exponentially and the success of the irrigation would be seriously compromised. When it is necessary to perform an irrigation session, the timer will be adjusted according to the desired settings and the system will start and stop automatically.
