I use BTEG in its most simplest form. I just lay newspaper (to 100% prevent weeds pushing through) and then wood chips. That’s it.
Currently this most basic implementation suits me. Ideally you would add a layer composted manure(below or above the the wood chip layer. It is up to you) to help quickly break down the wood chips. In my situation I want it to last to keep weeds at bay.
There isn’t a single weed in sight where I have laid the chips which is about 2 months ago.
