Vermiculite is an incredibly useful growing medium. Horticultural vermiculite can be used for many beneficial purposes
in the garden and can aid and assist in successful propagation, cuttings and plant raising.
One of the best uses of vermiculite is the plant propagation arena. Vermiculite is particularly useful when sowing fine to
very fine seed.Instead of covering the seeds with a covering of compost, which can be very heavy on tiny seeds and
can also form a hard cap,making germination very difficult, a small quantity of vermiculite can be used.
This is very light and presents no restriction or check on growth,the seedlings can easily break the surface and, because
of the lightweight granular texture of vermiculite,it does not form a cap on the top of the growing container or seed tray.
Vermiculite has the following benefits
Inorganic, inert and sterile Non abrasive Insulating
Ultra light weight Free from disease, weeds and insects
Slightly alkaline (neutralized with peat) High cation-exchange (or buffering exchange)
Excellent aeration characteristics High water holding capacity
Vermiculite is also used widely in seed and potting compost mix, as well as with container plant pots,
to provide a lighter, more friable compost mix.
