Default Sand on a lawn - how much and when?


"JB" wrote in message
...
I have a drainage problem across my lawn. The subsoil is predominantly
clay and after a typical winter it has become a boggy mess with a high
proportion of moss. I understand that by aerating it and top dressing
with sharp sand I can improve matters. The question is when do I do
this and how much do I add?

I have aearted the lawn in both autumn and spring (in one of the drier
gaps) can I top dress with sand no and if so how much do I add. I know
the question is a bit of how long is a piece of string but is this in
the order of 1Kg / sq m or 1 tonne / sq m. I'm guessing somewhere
inbetween but what sort of order I I looking for here?

TIA

sharp sand is no good in clay soils you need a 70 30 mix of sand and loam
aerate the lawn then top dress working in the sandy loam with a lute
