Vermiculite Soil: The Benefits And Uses
Although vermiculite soil is usually found packaged next to other potting soil, it is not technically a soil at all. It is, however, a mineral that has a strong resemblance to mica and when treated with heat the vermiculite expands into particles that are not only lightweight but it also contains many layers. These particles help to lighten up heavy soils while the layers hold nutrient and moisture to help plants grow.
Vermiculite takes a layered form of flat sheets in its natural state. When it is heated to create vermiculite soil, it expands the layers to about 25 times their original size. Small nuggets that are about a half inch long and absorbent and lightweight are created when heated.
Function And Benefits
Vermiculite soil can be used to aerate and lighten heavy soil, germinate seeds or use as mulch for outdoor shrubs and plants. It is also ideal to keep your house plant’s soil well-drained.
This soil is odorless, non-toxic and sterile and it will not rot or mold. The absorbent properties in vermiculite soil allow it to retain magnesium, calcium, and potassium that plants need. Additionally, if you mix it with composted pine bark or peat you can create an excellent home to hold plant food and moisture. Vermiculite soil also mixes fabulously with herbicides and pesticides.
A medium grade vermiculite soil is a standard that is used by professionals for most horticultural tasks, especially the insertion of cuttings. It can be used straight out of the bag, insert the cuttings and water thoroughly. You need not be concerned with over-watering as long as the container provides drainage. This soil will promote better than average root growth in less time.
If the native soil is sticky or heavy, mixing in a bit of vermiculite soil creates air channels that allow the soil to breathe. If you mix it in vegetable and flower gardens as well as potted plants, you can provide the necessary air needed to maintain vigorous plant growth. Also, sandy soils mixed with vermiculite will help the soil hold water as well as air that is needed.
Vermiculite soil eliminates the packed-down soil problem that often occurs in flower pots. You will mix the vermiculite with composted pine bark and/or peat. This will provide incredible moisture and air control, lighten and aerate the soil and it allows the roots to spread out in the pot requiring less watering. (click next button)
