My argument is that any material that has to be manufactured cannot be natural and far too many substances are being called a sort of perlite substitute such as I mentioned in another post, ground up Polystyrene. Fair enough I do break up Polystyrene boxes and use it as crocks in large pots then it is binned as it would have been in the first place.
Any DIY store will lift stuff into the back of a car and then I drop it in a barrow to where I leave it against the potting bench, natural stuff, easy to use and fully integrated into the garden later.
The first sort of mixer I remember was a sort of pumice processed into small balls, it was light did the job and seemed to disapear in the pot after a time.
I was brought up with all the old fashioned methods as the garden had to feed the family and yes all kind of weird things were used to fight the bugs, the best way was to let the hens wander the garden, they kept the nasties down.
My Father used them because there was nothing else and over time he knew what worked, when DDT came into general use he refused to use it, not natural he said and proved to be right.
Argue we will, who is right who knows, I do things my way as do others, we are gardeners, we work in the knowledge of our own experience and so may it ever be.
