Having just extended a flower bed to incorporate what has been
lawn for 40 years, I am left with some pretty solid clay soil.
Gypsum is recommended as a soil improver, but appears to be sold
in garden centres as a proprietary product costing nearly £5 for
2.5 kg.

On the other hand, I can pick up a 25 kg bag of multi-finish
plaster for under £5, and AFAIK this is essentially the same
material.
Any reasons not to go with plaster?
Chris, if you can find a Farmers Shop (not a Farm Shop) they may well sell
Agricultural Gypsum in 25kg bags, which is what I bought. Mine was old
stock, a bit lumpy, and I paid £5. each.
