I have read somewhere that it is good to spike the lawn every so often,
is this correct?
I must admit our lawn is rock hard at the moment so i assume like to
borders need digging over the lawn would need the same.
"Lawn aerators" as sold in N.America are wheeled
tools. The cheap ones merely drive spikes or knives
into the soil: the better ones drive in tubes that remove
a plug of soil (rather than compacting the soil either
side of the spike or blade. This is all theory because
the substrate of our lawn is sand, not clay.)
