I'm curious as to was is your particular use for vermiculite?

My dad used to use it in pots for cuttings of azaleas & rhododendron -
mixed with peat moss - back when he propagated them.

What else is it useful for?

I think it makes the garden soil a little looser, and it helps the soil retain moisture. Not too much like super wet, but just a bit.
