I have approx. 3 km of roads at work where moss is taking over. In an ideal world I’d leave it, however residents would complain and there’s an H&S risk of people slipping on it.
I’ve sprayed affected areas with iron sulphate numerous times, it turns the moss black for about a week then it just turns green again. I’ve gone from the recommended mix of 500 g per 10 litres to double strength, no joy.
I’ve tried using a nylon and wire brush head attachments on my brushcutters, these are fine for small patches but useless for such large areas that I have. It’s really persistent moss that sits in all the cracks of the tarmac, if it was a nice thick mat of moss it’d be easy to remove.
So how do I get rid of it? Would hiring in a proper big road sweeper even touch it? I don’t want to really use any nasty chemicals as a river flows through our land. Ideas please…
