Vermiculite is widely used in the horticulture industry as a soil amendment. When mixed with the soil, it provides better drainage and aeration. It is also used as a permanent soil conditioner and lasts much longer than other common soil conditioners.

Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It has the remarkable ability to expand to many times its original volume when heated at 1,562-2,012°F. The process of heating vermiculite via a furnace chamber in a controlled manner is called exfoliation. The vermiculite expands, producing particles that are much larger in size than they were originally.

Crude vermiculite consists of golden and silver vermiculite which are carefully classified into many sizes. This vermiculite is 3-6mm.

Horticultural applications of vermiculite:

• Soil improvement (structure, aeration, pH, etc.)
• House plants (as soil or amendment)
• Transplanting
• Seed germination
• Rooting cuttings

Other uses & benefits:

• Great option for incubation media for reptiles
• Inorganic, inert & sterile
• Non-abrasive
• Free from disease, weeds & insects
• Slightly alkaline
• High cation exchange
• Insulating
• High water absorption & retention
