i have access to a very well maintained green grass area, where
they
drill down every year with holes the size of a fat short cigarette,
and then fill the holes with sand presumably to assist drainage.

they then dump the drillings in a heap. would these drilling
leftovers be a good source of soil for pots? or would this soil
since
it has had grass growing on it for many years be kind of exhausted?

thanks for any help.

I'd use it like a shot. I'd stack it to rot for a while, if there's
enough: undecayed grass and roots aren't good news. If they take so
much trouble over the area, then it's very likely been fertilized
regularly, so you may not need to feed the plants for the first
couple of months or so: you could ask them if they use fertilizer.
I'd also check to make sure it's porous enough and not too acid, but
you could just mix it with compost and a bit of grit and get on with
it: most plants aren't as fussy as many gardeners!


Yes, but make sure they don't use "Weed & Feed" or nothing will grow.
