With sandy soil it's almost certainly not waterlogging, as you have

is your problem.


Or low nitrogen? Sand wouldn't hold nitrogen well -- and isn't lawn sand a
mixture of sand, iron sulphate, and some nitrogen fertilizer (ammonium sulphate,
something like that). Maybe addition of something organic would help, in
releasing nitrogen slowly, or a timed-release fertilizer.



Thanks for that Thomas. I believe you are right. I laid a lawn on
tposoil over old builders sand and other crap, and one area seems mossy
and poor growing: I assumed it was poor drainage, but even when sopping
wet it doesn't perk up, and when the cats crapped on it and made a
little pile of soil and crap, the grass shot up!

If you can't find cat crap, fish blood and bone seems to encourage
grass, and once the grass is there, the moss cannot cope.

Don't over do it though. I spilt some and the grass died off, except or
a ring round the spill that shot up!
