It was once suggested to me to use old broken
pieces of drywall as that's gypsum and easily handled and every home
improvement center has broken pieces of drywall they'll give away........

For 'drywall' read 'plasterboard' in the UK?

Yes -they both contain gypsum ( calcium sulphate). Drywall tends to be the
term used when you place plasterboard (often foil backed) on a soothing to
hide a damp wall.

A problem with using plasterboard on the garden is that it's
inevitably in lumps, whereas powdered gypsum or builders plaster can
be spread much more evenly, and it will dissolve and wash into the
ground more quickly.
