I continually get this every winter in one place where the concrete is more pebbly, and hence rougher, and was wondering if there was something we could put on it to stop it. I'll probably need to pressure wash it off as now it looks like tiny grass shoots are growing in the moss!
Nature is taking over, but its very slippery when wet, so I'll have to do something. Brian
There are several possibilities. Perhaps the simplest is a strong solution of washing soda watered on. A variant of this is to scatter washing soda crystals on the mossy area and lightly water-in with a watering can. Leave for a few days and then scrape or brush up the dead moss. Another method is to water the area with a solution of Jeyes Fluid, but the smell lingers for days, or even weeks, and it will stain the concrete for a while. Watering with a solution of sulphate of iron will also kill the moss, turning it black, but it will also stain the concrete, and your hands if you get it on them. Pressure washing will also shift moss, as you say. Lastly, there are commercial moss killers available, the Royal Horticultural Society (RHS) has a list, together with some other methods, here
Yes did that last year, and managed to kill some of the lawn as well..:-) Still, I have a cunning plan to stop run off this year using a bit of old plastic and a plank! Brian
Ah, not up to speed on the life cycle of moss, are these then like the bits that propagate it? I was never a gardener, more of a sitter out in the gardener under a treeer. Brian
Dairy Hypochlorite from Agricultural suppliers (?Deosan), = full power bleach, not like the watered down stuff sold to the public. Bookers also do 5 litres of strong bleach, with added sodium hyroxide.
