Drip Irrigation Parts

I weeded and amended the soil in my garden. Now I want to put in drip irrigation, landscape fabric, and microbark. I want to put the plants at a later date. If the irrigation pipe (no transmitter tubes) is under the fabric there is the advantage of them being out of sight, but the disadvantages of not knowing where they are when you walk in the garden and not be able to obtain parts that may be leaking. Thank you!

The pipes should be underground. If it is high, it has a better chance of getting upset that below. The chance that anything happens to him under the ground are slim. If you fear her, or find the tubes later. Make a map on paper.

Spoil yourself and save money - use paper instead of fabric. The paper is much more effective, the fabric will always be weeds to grow through the material making them impossible to remove (except chemical) and planting (X cut, dig in cloth) is a buggar.

Okay, you've answered your question.

You seem to have answered your question. The fabric must be under the pipes as much as possible, because you may very well need to access the pipe (and you certainly need to see where they are), then you will not need to obtain new tissue.

Above the block weeds if something happens, you must cut the weedblock to try to find the leak. If you bark or rock the most serious.

Not really important. The drip hose will do its job either.
