Drip Irrigation Does Landscape Fabric Go Over Or Under Drip Irrigation Pipes?

Does landscape fabric go over or under drip irrigation pipes? - drip irrigation

I weeded and amended the soil in my garden. Now I want to put in drip irrigation, the structure of the landscape and microbark. I have found in plants at a later date. If the irrigation pipe (no transmitter tubes) is in the substance is not the advantage of being out of sight, but the disadvantages of not knowing where they are when you go into the garden and in the absence of reaching parts of the leak. Thank you!
