I don't think it did, though I don't know why not. The bill just says they have sprayed with a micronutrient feed that gives good colour; it also helps with the control of moss and indeed (after the 2nd application after I had complained that the first had a series of black lines, with large gaps between) it does seem to have killed off most of the moss. I think I am going to give them the heave-ho and revert to applying a combined moss killer, feed and weed if I can get anyone to do it it for me. Or move to a flat!
