Essentially vermiculite is used in the horticultural industry because it provides aeration and drainage, it can retain and hold substantial amounts of water and later release it as needed, it is sterile and free from diseases, it has a fairly neutral pH, and it is readily available, non-toxic, safe to use, and relatively inexpensive. Nevertheless, for decades Vermiculite (and perlite) have been used by professionals, dedicated amateurs and gardeners.
