HORTICULTURAL VERMICULITE:

Horticultural Vermiculite has the excellent property of improving soil aeration while retaining the moisture and nutrients necessary to feed roots, cuttings, and seeds for faster growth

Like perlite, horticultural vermiculite is permanent, clean, odorless, non-toxic and sterile. It will not deteriorate, turn moldy or rot. The pH of vermiculite is essentially neutral (7.**9.5) but owing to the presence of associated carbonate compounds, the reaction is normally alkaline. It also will vary (become more alkaline) with changes in processing techniques and time, and with the presence of moisture. The pH, color and chemical compositon of vermiculite also will vary from mine to mine.
Vermiculite possesses cation exhange properties, thus it can hold and make available to the growing plant ammonium, potassium, calcium and magnesium.
When mixed with peat, composted bark, organic compost, or natural soils, vermiculite like perlite helps promote faster root growth, and gives quick anchorage to young roots. These mixes help retain air, plant food, and moisture, and releases them as needed by the plant.
Because vermiculite is very light and easy to handle, it easily mixes with soil, peat, composted pine bark and other composted organic materials, fertilizers, pesticides and herbicides. And when used as a carrier or bulking agent, it ensures more even distribution.

Root Cuttings **-Medium grade vermiculite is the standard among professional nurserymen for many horticultural uses including the insertion of cuttings. Like fine grades of perlite, these finer grades of vermiculite may be used directly as poured from the bag. Simply water the vermiculite thoroughly and insert the cuttings. And if the container has sufficient drainage, over wetting or watering normally is not a serious concern.

Soil Amending or Soil Conditioning**-Where the native soil is heavy or sticky, gentle mixing of perlite or vermiculite in proportions 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; and when soils are sandy, the use of vermiculite will help the soil hold the water and air needed for growth.

Seed Germination**-Use vermiculite alone or mixed with soil or peat, and very little watering will be required. You will notice that not only more seeds will germinate, but they will germinate faster. 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 of water should be enough.

When vermiculite is mixed half and half with soil, peat, composted pine bark, or other properly composted soil materials, no additional feeding normally is required right up to the time of transplanting. Because vermiculite is sterile, the threat of what some professionals call "damping-off" is virtually eliminated. And later, seedlings can be removed from vermiculite with little danger of breaking off hair roots, and the dense root growth enables young plants to take hold immediately.

House Plants and Containers**-Vermiculite eliminates the problem of compacted soils in flower pots. Mixed half and half with soil, peat, or composted soil products, it provides excellent aeration and moisture control, and it lightens the mix so larger pots can be placed on shelves or hung from the ceiling. In addition, vermiculite amended soils allow the roots in a flower pot to spread out quicker and more evenly, and require far less watering.

Storing Bulbs and Root Crops**-Pour vermiculite around bulbs placed in a container. If clumps with bulbs are dug out, allow to dry for a few hours in the sun and then place them 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.
