I've just been told that the curled under leaves on my italian prune trees
are caused by magnesiom deficiency and I should apply a few pounds of
epson salts under each tree.

Your search might be easier if you looked for it using the correct name
which is 'Epsom salts'. It is named after the town of Epsom in the UK.

I would be extremely suspicious of taking any advice to use that amount of
Epsom salts under any tree.
