Oh you’re welcome, and yes that’s the idea. It’s used heavily in grass applications because the blades have no problem finding their way through. Plant plugs or even larger plants can be installed through the blanket by cutting an ‘X’ shaped incision in the blanket, pulling the flaps back, planting in, and then replacing the flaps around the plant. I use the large metal ‘U’ pins commonly seen in sod applications to pin the blanket down every few feet. Hope this helps,
p.s. I have used coir fiber but to my knowledge there is no domestic production of that material, so I tend to discourage its use as needlessly wasteful in terms of carbon footprint.
