If you do not have relatives or trusted friends who are available to take care of your garden during your absence, it is a good idea to estimate how to install an automated irrigation system that will wet your greenery even when you are not at home.
Contacting specialized firms or experienced gardeners would be the most logical solution if it were not that, with the times of crisis that we are going through, a project done by expert hands could be quite expensive in monetary terms. And then, better go to a do-it-yourself center and recover all the material necessary to build a state-of-the-art system with your own hands; in large DIY centers you will surely find competent personnel who will be able to direct you and advise you on the products most suitable for your needs.
However, it should be pointed out that it is not a simple job but a commitment that will take a long time; the ideal solution would be to install your system when the garden or garden has not yet been created, such as if you have recently entered the new house.
If, on the other hand, the garden already exists, you must realize that it will be necessary to sacrifice a part of it ruining the grass for excavation and the installation of pipes and drips. In this case, it is better to start the works during the vegetative rest so that everything is ready when the blooms will resume.
First of all it is good to evaluate the type of system you want to install and that will best meet our needs.
We can choose between three different types depending on where the tubes will be placed: the first is above ground and is one of the simplest to fix since the tubes are completely on the surface and it is not necessary to dig and remove clods of earth.
The water will be directed to the points we set by conveying the jets through the appropriate lances.
The second type of plant is defined drop-shaped and is generally used to wet vegetable gardens and flowers that badly bear direct splashes on corollas and leaves.
The tubes used are dotted with micro-holes from which the drops fall, and possibly from external drips to be anchored with special clamps.
The last plant is the one that requires more work and has a higher cost than the previous ones, but on an aesthetic level it is the one that gives the impression of having a well-kept and tidy garden.
In this case the pipes are hidden underground after having carried out a not too deep excavation and the water reaches the surface by means of jets which, with the water pressure, rise and fall.
For all solutions, however, it is advisable to buy a timer or timer that will allow us to start the irrigation in the desired hours (even at night) and for the set time.
Before starting work, arm yourself with paper and a pen and make a diagram of which areas should be reached by the water and check that there are no particular obstacles that could deviate the jet.
Now that you have clear ideas and have taken the measures, all you have to do is go and buy the material.
What you need will be several meters of pipe, the irrigation outlets and the timer to be attached to the fountain (if available in your garden) or to the water intake.
The most suitable tubes for this kind of work are those in polyethylene: they can also be cut to be more easily connected to each other by means of the special fittings that can be purchased separately.
As for the sprinklers, it is better to opt for the sprinklers that have a directional jet and that, therefore, reach the affected green areas more easily.
Finally, for the "timed" control unit, there are battery or electric units and they have different costs depending on the different functions: the cheaper ones are around 70 euros.
And now begin the excavations: you will only need to go down to about twenty centimeters in depth, taking care to keep the removed earth at hand as it will be used to cover the pipe.
Pay attention to the points where the pipe will have to bend: it will be sufficient to cut the pipe and create the elbow with another part of pipe joining the ends with the fittings.
Put the sprinklers in the desired places by making them come out of the ground for about 10 centimeters.
Now that the work is finished, it is better to do some tests before repositioning the whole earth and closing the holes; if something does not work it will be quicker to resolve any problems.
Take a look at the result while the system is running and check that all the garden is reached by water: if you have placed the pipes only along the perimeter it is clear that the sprinklers will have to "shoot" water towards the center.
If, on the contrary, you have planned more jets also in the middle of your area, keep in mind that in this case you can buy those with a 360 ° rotation.
FILTERS FOR IRRIGATION SYSTEMS
If after some time you notice that your water jets no longer have the initial pressure, it means that the internal filters have been damaged due to water impurities and the massive presence of limestone.
Carefully unscrew each sprinkler when the system is switched off and check the condition of the links inside the filter.
If they are dirty and have deposits of earth, sand and limestone, then it is advisable to wash them under running water first and then clean them further using compressed air to ensure that even the smallest residues disappear completely.
If instead the impurities of the water and the limestone have seriously compromised the filter even causing cracks on its surface, then it is good to get new filters in replacement.
It's time to reassemble the sprinklers by assembling the filter in the cover sheath; it is a delicate operation as there is the risk of causing other dirt to slip inside, which could again affect the operation of the system.
If you have done things the right way, once the control unit is put back into operation, you will surely notice that the water will come out of the jets with the original pressure and will be able to reach every point of your green areas.
Checking the status of the filters is a job that should be done with a certain frequency, just to avoid having to run into more serious and certainly more expensive problems.
