@KT53 I didn't mean it as correcting you, more making exactly that point - and yes, I am sure their wording is deliberate and careful.
It turns out that several professional gardeners of my acquaintance have come across this causing problems when looking after people's lawns, but haven't known what it was or that it was a widespread problem.
The practice is wrong on so many levels!
i suggest that the first high profile legal case against the owner of a lawn by a celebrity whose heel has caught in the plastic and they’ve fallen and been injured will focus their minds considerably faster than appears to be happening at the moment.
I found it very interesting how many had seen it but not realised what it was. When I first came across a small patch catching my rake, it didn't occur to me that it was embedded in the entire lawn. I'm trying to open eyes, one by one.
Searching for Oxygrid, I found this. I wonder if Rolawn started using it around 2015?
Ghost fishing is the relevant term if you want to look
I live in west central Scotland - not where that photo is...
