Hi
There is no need to water the right plants but if you're talking about a vegetable plot then it is necessary.
Perforated tubes are not much use if you live in a limestone area. Or if your soil is alkali. If you live round here then though the PH is not high the soil is not acidic. Does your kettle "fur up"?
When you turn off the water in your perforated tubing some stays in the perforation itself and the sun evaporates the water leaving a little limestone. Eventually  the hole blocks up.
Little sprinklers fitted into 20mm tubing are much better though obviously the same problem occurs but the holes are much bigger. But the sprinklers can be taken out and left in white vinegar which dissolves the limestone and then replaced in the tubing. Better if you can find sprinklers that have the spigot threaded. Much easier to take out. The red topped ones eventually disintegrate in the sun (3/4 years) Black ones are better if you can find them. Threaded black ones are available in some DIY stores in France but here?

Good luck
