Product Description
?Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire resistant, and odorless. In lightweight plaster and concrete

?vermiculite provides good thermal insulation. Vermiculite can absorb such liquids as fertilizers, herbicides, and insecticides, which can then be transported as free-flowing solids.

Usage
Medium grade vermiculite is the standard among professional nurserymen for most horticultural uses including the insertion of cuttings. Vermiculite may be used directly as poured from the bag for root cuttings. Water thoroughly and insert cuttings. Over wetting is not a serious concern if container drainage is provided. Vermiculite will promote maximum root growth in less time.
Soil Amending?OR ?Soil Conditioning
Where the native soil is heavy or sticky, gentle mixing of vermiculite up to one-half the volume of the soil is recommended. This creates air channels and allows the soil mix to breathe. Mixing vermiculite in flower and vegetable gardens or in potted plants will provide the necessary air to maintain vigorous plant growth. Where soils are sandy, mixing of vermiculite into the soil will allow the soil to hold water and air needed for growth.
Seed Germination
Use vermiculite alone or mixed with soil or peat. Very little watering is required. More seeds germinate - faster germination too! When vermiculite is used alone, seedlings should be fed with a weak fertilizer solution when the first true leaves appear. A tablespoon of soluble fertilizer per one gallon (3.78 : 1) of water will do.
House plants
Vermiculite eliminates the problem of packed-down soil in flower pots. Mix half and half with soil, peat and/or composted pine bark. It provides excellent air and moisture control for house plants. Lightens and aerates soil. Roots can spread out through the pot. Less frequent watering is required. TRANSPLANTING -Dig hole at least six inches larger than plant roots. Mix vermiculite with top-soil that has been removed, then place mixture around roots. Vermiculite, when mixed with soil before transplanting shrubs, bushes or trees, will permit roots to branch-out and penetrate deep into the ground. Vermiculite protects roots from drying action of wind and sun. Provides even moisture control - assures healthier plants.
Summer or Winter Mulch
Use two or three inches of vermiculite as a mulch around shrubs, roses, tomatoes, dahlias, and garden plants. Prevents drying out, insulates plants against cold. Plants protected with vermiculite withstand wide variations in winter temperatures. Vermiculite does not mat down or become soggy because its pore structure prevents it from becoming saturated. Applied around plants after first heavy summer rain, it will prevent drying of soil and damage to plant. In spring the mulch can be mixed into soil as a conditioner.
Home Floral Arrangements
Dip your container into vermiculite -fill and level off. Hold container under water faucet and thoroughly saturate the vermiculite. Pour off excess water. Insert the flowers for a neat, colorful arrangement. Flowers arranged in vermiculite will remain erect and fresh for days and there are no water spillage problems to worry about. With taller containers all you need to use is vermiculite. With centrepieces chicken wire may be necessary.
