How should the below ground drip irrigation line be laid and used?

In lawns, the drip irrigation line should be laid about 10 cm deep. In beds, etc., the drip irrigation line should be laid about 20 cm deep. Outside of the frost season (between approx. April and September), there should be no longer than three weeks between watering periods, otherwise the roots will try to grow into the drip openings. The drip openings can face any direction, upwards, downwards or sideways.
