I can second that. Mine was half moss, and was being taken over
by unsuitable weeds. Lots of ferrous sulphate and fertiliser,
one go of (yuck) Verdone, and it is quite reasonable. Of course,

Spot weeding on lawns with Verdone is OK but I wouldn't be keen on
applying it to the entire lawn. I quite like some of the wildflowers.
(I draw the line at dandelions and buttercups though - too invasive)

I did most of it, because I normally compost everything, and didn't
want to have to select out the cuttings to compost!

the moss is returning now that we are into the soggy season,
but it was the dominance that was the problem.

Buy 1 Kg tubs of ferrous sulphate online, or 5 Kg if you have a
large lawn.

End of season spring weed and feed is generally very cheap at this time
of year to make room for dracula/santas grotto (repurposed after 31/10).

Maybe a bit late to catch a bargain now but it keeps OK in a dry
location. Cutting the ferrous sulphate with ammonium sulphate and sand
so you dilute it will give the grass a head start and slightly help
drainage. A good hollow tined fork will improve drainage (although they
tend to bend or jam up on my pebble ridden boulder clay subsoil).

The lawnsmith recommends watering ferrous sulphate in, so I mixed
it with commodity lawn fertiliser (the one WITHOUT weedkiller),
and did both at the same time.
