Vermiculite is commonly used in horticulture as well as agriculture for both its water-retention and soil aeration properties. Predominantly neutral pH (generally ranging from 7 – 9.5 pH), however, depending on where the resource was mined it can be more on the alkaline side. Vermiculite is also widely used for its nutrient retaining properties. Although vermiculite is similar to perlite, it provides less aeration but retains water and nutrients at a much more efficient rate. It is sterile, non-toxic, and mold resistant. Vermiculite has been used for thousands of years, whether knowingly or unknowingly, as it naturally occurs in rich volcanic soils that have been favored by farmers throughout the ages.
Horticultural uses of vermiculite:
Used as a growing medium enables the plant to fairly easily attract and absorb the ammonium, potassium, calcium, and magnesium necessary for a more vigorous growth. Often mixed easily with lightweight substrates and can even lighten your soil It can be used in pots, flower beds, on grass, and for hydroponics. It encourages growth in almost any plant and is an excellent companion to the Rapid Roots Grow Pots, and can be used on a wide variety of plants. A few examples include but are not limited to: newly seeded lawns, roses, dahlias, tomatoes; berries, bulbs, herbs, a huge variety of vegetables, all the way to fully grown trees It helps to retain moisture. This means less watering is required while still allowing ample drainage, it is 100% non-carcinogenic.
Vermiculite can be used for transplants; encouraging root growth in clones and more. Absorb 3 to 4 times its weight in water, acting like a sponge in absorbing water and nutrients, releasing them slowly over time. Highly recommended for water-loving plants. **When mixed with coco peat, composted bark, organic compost, or natural soils, vermiculite helps promote faster root growth and gives quick anchorage roots. It helps to eliminate soil compaction problems in plants. Is a great insulator for plants from cold and warm weather alike, therefore perfect for both indoor and outdoor plants
Are vermiculite and perlite organic?
Both resources are no more organic than rocks. They are inorganic compounds, however, most importantly, they are not synthetic. Plants grown using vermiculite and perlite are still considered organic as they are naturally occurring resources.
Vermiculite vs Perlite:
They are both mined minerals that can be used for insulation and water filtration. They can both hold moisture and improve drainage in soils. While both vermiculite and perlite hold water, they work in different ways:
– Vermiculite absorbs water and nutrients slowly releasing it over time, much like a sponge.
On the other hand, Perlite is round and holds its water like a little cavern structure. It holds much less water than vermiculite but holds much more air.
