Hypo mix and pressure wash for instant results or bio treatment that will work over weeks and months , personally I would wet it down then 4-1 mix of hypo to kill the algy give it a light rub with wfp if you have that if not give it a scrub with a broom re app,y hypo mix if needed wash down with pressure washer job done

As per PJJ above, spray with 3-4% mix of hypo, agitate with brush and leave to dwell for 30-45mins then PWash. Repeat if necessary
Thanks! Also wondering how to clean uo this, stone resin. They previously used a electric jet wash with no luck!
Thanks again!

Not done any stone resin cleans but would think pressure washing with a flat surface cleaner on a lower setting would work fine I would try a bit first as a test , don’t cone across them very often down hear

The first one, I would be worried about the plants and may be an idea to dig them out and replant next day.
