Expanded Vermiculite

Product description

Vermiculite can provide trace elements to crops, it will expand under the action of high temperature, adjust the pH value of the soil, and can maximize the consumption of oxygen by the root breathing of the plant, thereby reducing the rot caused by the stuffy root.

How to Use Vermiculite in a Soilless Potting Mix

You can buy soilless potting mixes that already contain vermiculite. But you may find that you can save money by buying the vermiculite separately and mixing it yourself. In that case, here is a general-purpose formula to go by:

• 4 to 6 parts sphagnum peat moss

• 1 part perlite

• 1 part vermiculite

How Vermiculite Differs From Perlite

Perlite is that white material in soilless potting mixes that looks like little chunks of styrofoam. In its natural state, it has a pearl-like shine to it that accounts for the name, "perlite." While vermiculite and perlite are two completely different substances, they do have some things in common; both are:

• mined out of the ground (perlite is a volcanic mineral)

• later heated, causing them to expand

• used as soil amendments, both in soilless potting mixes indoors and to improve garden soil outdoors

• lightweight

• sterile

• have a neutral pH

• contain no nutrients

Why Vermiculite Is Used in Soilless Potting

• Vermiculite boasts several characteristics that make it useful to gardeners. The product is:

• Lightweight

• Highly absorbent. Its particles absorb water and nutrients (which must still be supplied) and retain them in a soilless potting mix. Whenever the plants' roots are ready to use the water and nutrients, they are able to absorb, thanks to the vermiculite.

• Neutral in terms of soil pH, so that you do not have to worry about compensating for pH alterations due to the presence of the soil amendment.
