That Preen fabric, it says it’s not UV protected. Are you using it with mulch? Here, it won’t have mulch so will get full sun and that’s what some of the reviews complain about (but I don’t believe reviews all the time). I garden barefooted to get a better toe grip, so mulching would hurt my feet and it’s work to put it in and I’m lazy.
We have never mulched the fabric. If my wife hadn’t cut too many unused slits in it, we would be using it again. I am going to use it again on my container beds. Its tough stuff, was recommended by JustADumbBlonde a few years ago. Its cheap, and last long. It is a contractor grade, not the flimsy stuff from Lowes. We have never pulled weeds or hoed. It’s planted, the drip system is running, we have nothing else to do till we pick tomatoes and peppers..
We have pictures on my FR homepage.
