What do I do to my lawn after treating it with lawn feed & weed and moss killer I have got as much as I can of the blacken moss off but there are loads of bare patches do I add grass seed to it or will it recover on it's own .

Oh! And a top dressing of sharp sand liberally sprinkled on the lawn is a good conditioner. It will help the roots to grow strong... Strong roots, healthier shoots. ;o)

You could try spiking the lawn to aerate it. It should recover, but if the patches are large then apply grass seed.
