Vermiculite is the geological name given to a group of hydrated laminar minerals which are aluminum-iron magnesium silicates which have the appearance of mica, and is found in various parts of the world.
When processed for horticultural use, the mineral is subjected to intense heat, expanding it into accordion-shaped granules with countless layers of thin plates.
Horticultural vermiculite has the excellent property of improving soil aeration while retaining moistre and nutrients to feed roots, cuttings and seeds for faster, maximum growth.

Horticultural Vermiculite.
Seed Germination:
Many commercial growers use vermiculite to cover sown seeds. Since water and relative humidity play an important role in the germination process, seed planted with vermiculite will be protected against fast drying conditions.
Soil mixes:
When mixed with soil or soilless media, vermiculite promotes aeration helping young plants to take hold easily. Seedlings will
also be easier to remove with less danger of breaking off hair roots. Its high water retention will also decrease the irrigation
frequency by naturally regulating water availability in the seed tray.
Horticultural Vermiculite.
Rooting cuttings:
Professional nurserymen use vermiculite for the insertion of cuttings. Use directly as poured from the bag, water thoroughly and
insert cuttings.
Soil amending:
Where native soil is heavy (clay), mixing vermiculite is recommended to increase air space. Where the soil is sandy, mixing
vermiculite is also recommended, Its water retention allows the amended soil to hold more water, decreases drought stress, and
maintains vigorous plant growth.
Storing bulbs and root crops:
Always allow moist bulbs to dry a few hours and then place in cartons and cover with vermiculite to absorb any excess moisture.
Since it absorbs moisture, vermiculite helps protect your bulbs against mildew. The insulating properties protects your bulbs from temperature changes.
