I’ve had the worst moss problem on my crazy paving (alas I still have crazy paving: maybe it will come back into fashion one day…) this year. Last year I had moss growing between the slabs which I removed with one of those wire brushes, but this year it’s been like a green slime everywhere and is very slippy. I don’t know what to use on it as the dog needs to go into the back garden. I’m hoping some dry weather will kill it off.
'Wet and Forget' or similar product will get rid of your moss and slime. I spray on finely in the spring and one treatment lasts for at least a year. Also useful for green algae on walls, sheds and fences. I do it on a warm dry day so that is dries before my cats walk on it. I can't remember what the blurb says regarding pets. Good luck!
