Ours are on the ground, growing through holes in weed control fabric
When I first read this I was thinking about the woven fabric, like mypex, which shreds. Then I realised you probably meant the non-woven material, like plantex. I didn't want to cut from our big roll, as we have more paths to construct, so I had a rummage in the "too good to throw out" section, and found some planting bags left over after setting up our pond about 20 years ago! Spent this morning cutting them up and tucking the material under the plants and fruits. Looks promising.
