My lawns are looking very poor, 60% moss, plus white patches.

I think the problem is due to the turf being layed over heavy clay soil,
actually I know this is the problem, new build syndrome, will top dressing
do any good and if so what mix should I use?

The ideal solution would be to remove a foot of clay all round and
introduce
some organic material and fresh soil but I cant afford this.

Thanks

dont top dress until autumn give the lawn a good spike most moss is the
cause of poor aeration in the soil profile apply some moss killer and a
dose of sulphate of iron one the moss goes black scarify and box off then
brush some seed into the bare areas this should reduce the moss also apply
a spring summer fertiliser to boost the grass regular spiking every
fortnight will help also box off your cuttings when mowing the grass as
build up of thatch and organic material will add to the problem good luck
