If you start breaking up the glass with a hammer or anything else to
shatter
it then you will have small shards of glass in your soil for years to
come.
Just treat the glass (Broken or not, with care and respect)

You make a point there, but it is minimised because you don't go slashing a
hammer about, you knock it downwards, and the shards (small and big pieces
of broken glass) fall within the controllable ambit of the greenhouse inside
base and it is better to cover the glass with a piece of blanket to keep
small splinters - not shards off your clothing and body.
And carefully clean up the debris. though the sharp edges of small pieces of
glass soon weather-blunt.
Nevertheless it has to be conceded that any pieces of glass in the worked
soil is bad news for workers who have to put their hands into it,-
especially in these days of rampant compensation cases.
None of the above detracts in any way from your thoughtful and correct
observations.
B.T.W.; Have you ever heard of the clematis Nursery at Woodplumpton Lane Nr.
Preston, Lancs?
He was my brother and a world Authority who travelled a lot, lecturing -
sometimes as far as Poland, where as you know quite a few new clematis were
bred.
Do *you* specialise or trade generally?.
Best wishes!.
Doug.
