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 moisture and nutrients to feed roots, cuttings
and seeds for faster, maximum growth.
· Horticultural vermiculite is permanent, clean, odorless, non-toxic and
sterile. It will not deteriorate, turn moldy or rot. The pH is essentially
neutral (7.0) but owing to the presence of associated carbonate compounds,
the reaction is normally alkaline. The pH, color and chemical composition of
vermiculite will vary
depending on the source from deposits around the world.
· horticulture Vermiculite possesses caption exchange properties, thus it can hold
available to the growing plant ammonium, potassium, calcium and magnesium.
· horticulture Vermiculite, when combined with peat or composted pine bark compost,
promotes faster root growth and gives quick anchorage to young roots. The
mixture helps retain air, plant food and moisture, releasing them as the
plant
requires them.
· Vermiculite is very light in weight, easy to handle and easily mixes with
soil, peat, composted pine bark, fertilizers, pesticides and herbicides. Its
use as a carrier and bulking agent ensures more even distribution in mixing
operations.
ROOTING CUTTINGS - 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!
Whenvermiculite is used alone, seedlings should be fed with a weak
fertilizer solutionwhen the first true leaves appear. A tablespoon of
soluble fertilizer per one gallon (3.78 : 1) of water will do. Where
vermiculite is mixed half and half with soil, peat, or composted pine bark,
no additional feeding is required up to the time of transplanting. Because
vermiculite is sterile, the threat of damping-off is virtually eliminated.
Seedlings can be removed from vermiculite with little danger of breaking-off
hair roots, and the dense root growth enables the young plants to take hold
immediately.
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.
STORING BULBS AND ROOT CROPS - Pour vermiculite around bulbs placed in
container. If clumps are dug, allow to dry for a few hours in the sun and
then place in cartons or bushel baskets and cover with vermiculite. The
absorptive
power of vermiculite acts as a regulator that prevents mildew and moisture
fluctuation during the storage period. It will not absorb moisture from the
inside of stored tubers, but it does take up free water from the outside,
preventing storage rot. Stored tubers are protected from even the most
severe temperature changes.
GREENER, HEALTHIER LAWNS - When preparing seed bed for new lawns,
mix 3 cubic feet (85 : 1.) of vermiculite per one hundred square feet (9.3
sq. meter) or (100 : 1. per 10 sq. meters). After seeding, cover entire area
with vermiculite about one-quarter inch deep over seed. Water thoroughly
with fine spray. Vermiculite hastens germination. More seeds germinate too,
so your lawn is denser, richer. Vermiculite acts as a constant reservoir of
moisture, retards drying out and scorching during dry spells.
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 centerpieces chicken
wire may be necessary.
