Like I said, I have been using drip tubing for many years without any issues. It's the most efficient way to water - when used in the appropriate application.
Many photos in my files showing it's use.
Here is a couple from a project of mine way back in 2002.
How else would you water this narrow bed?
A great visual in this photo showing the wetted soil areas after the system was run a short period of time....
That was just to test the system. Pull out the tubing - then plant - then lay in the tubing along the plantings.....
Then add mulch.....my SC photo bombing my shot there.....
Boom.....
