I am probably going to upset everyone, but I would dilute it as much as
possible, then pour it on to the ground in a corner of your garden.
Copper is not unknown in garden chemicals, and the copper sulphate would
certainly get rid of any peach curl virus that happens to be there!
Dissolved metals? If there is any iron content, your hydrangeas will produce
blue flowers, and if it is copper, they will produce a blueish-pink.
What it will do to other plants is... an interesting experiment??????
Unless you have a stream running through your garden, by the time it reaches
the water table, it will be so well filtered that nothing will be there
except water.

Hi chaps
In my workshop I have a spent tank of sulphuric acid - it contains so much
dissolved copper that it is probably mostly copper sulphate now. Does anyone
know of a safe/legal way to dispose of it? Could I mix an alkali with it to
neutralise it, and if so would it be safe to tip down the drain? I expect
this might still be taboo on account of the dissolved metal. Any ideas
anyone?
