He wants to dig sand into the borders. Fine, but he has specified
"horticultural sand". I think it would save him money if I just used
ordinary sharp (concreting) sand from a builder's merchant. What does
the team think?

Yes, sharp sand is the stuff, but the problem is that you need a LOT
(or of anything, else for that matter) to make any difference.
