In this case the hardpan is chalk a mile or more thick!

OK, but cracking the top of it cannot hurt can it?

I'll ask madam if she minds me wrecking her lawn with me pickaxe!

 

Seriously, access is rubbish and no way would she countenance her garden being mined on the offchance that it would help. We're not even talking abut the topsoil here; you'd need to go down a bit first.

 

Thanks anyway.

Sorry to mislead; the steel "wrecking bar" referenced is <4cm wide so would make perceptible holes in lawns. They can go ~1m deep ime.

 

It's work, but often quite worth the effort.

You've lost me now. I couldn't put a crowbar a metre into any soil, yet alone chalk!
