I use iron sulphate on the lawn but it would stain the paving slabs.

Yes - you'll certainly end up with ginger-coloured slabs.

Given half a chance, my lawns end up with 90% moss and 10% grass. I used
to be able to get ferrous sulphate in 25kg bags. In the 1980s a works
colleague (who was in a gardening society that got discount for bulk
purchases) got me one from time to time, for around 6 pounds each. The
last one I got (around 2000) was from a local hardware shop, for around
10 pounds. The next time I wanted a bag I was told the EU had listed it
as hazardous (25kg might give you a hernia??), and you could only get it
in tiny 1kg boxes - which cost around 7 pounds.
