PERLITE vs VERMICULITE IN GARDEN SOIL | Benefits and Difference Between Perlite and Vermiculite

August 24, 2019


Hello Friends, Todays Video is on the Benefits
of Perlite and Vermiculite in Garden soil, then, the differences between Perlite and
Vermiculite and lastly the disadvantages or drawbacks of using them. Coming up.. Imagine this scenario, You are standing in
the garden and trying to decide which one to mix in your potting soil – whether perlite
or vermiculite. The differences between perlite vs vermiculite
are important to know for the prosperity of your garden. Perlite and vermiculite are two different
substances used for a common purpose, that is for moisture retention and aeration in
soil. That means to hold water within soil for plants
and also to improve air circulation or aeration of potting mix. Perlite and vermiculite are quite different
in composition and also performance wise. Determining which is better for use in your
garden depends on your plant type and its requirements. Vermiculite is an aluminum-iron-magnesium
silicate that resembles mica in appearance. It is heated to expand the particles and form
flakes. It has a neutral ph of 7.0. Vermiculite can soak up 3 to 4 times its volume
in water and absorbs and retains moisture. It also attracts and retains plant nutrients
such as potassium, magnesium, calcium and phosphorus. Vermiculite is a spongy material that is dark
brown to golden brown in color. It is shaped like flakes when dry. Perlite is an amorphous volcanic rock that
is rich in silicon. To use as a potting medium, perlite is crushed
and also heated to expand the particles. Perlite has a PH of 6.6 to 7.5. Perlite looks like porous white balls of varying
grades that looks like white granules often resembles foam balls or thermocol balls. It can be easily crushed with your fingers
or on pressure. But still even the smallest particle of perlite
serves its purpose of moisture retention and hold air within. There are microscopic bubbles in perlite which
serve this function. In Comparison, Perlite and vermiculite are
both good at retaining water, but vermiculite acts more like a sponge, holding much more
water than perlite and offering less aeration for the plant roots. Perlite retains less water, but because it
is porous it allows excess water to drain more readily than vermiculite and improves
soil aeration. Perlite cannot be used in only garden soil,
because its readily crushable and will not serve the purpose fully due to compression
by heavy garden soil particles. Best use of perlite is in potting mix with
various compositions like coco peat, peat moss, sand and other material. Please watch my separate video on Various
Potting Mix Formula. Well, To summarise or list out the uses of
both vermiculite and perlite: 1. They prevent soil compaction, improve aeration
and retain moisture. 2. They are also used in propagation of plants
from cuttings that is cloning. 3. They are also used as seed starting mix for
seed germinations. 4. They are also used to grow indoor plants and
succulents. Well, Now the Take home message is that, Vermiculite
is ideal for plants that prefer lots of water and Perlite would dry out too rapidly for
water-loving plants. However, Perlite is favourable for plants
such as cacti, which need a well-drained soil. One bad effect of overuse specially of Vermiculite
is – The excess moisture retained by vermiculite would lead to root rots or plant death. So in any General Potting Mix, use no more
than 10% of these substances specially Vermiculite. So there we have it folks, that was our informative
episode on The uses and differences between Perlite and Vermiculite in garden. If you like the video, please give a thumbs

    This video is so redundant. Instead of saying, "Perlite and vermiculite are used for moisture retention and aeration", you say, "The differences between perlite and vermiculite are important to know for the prosperity of your garden. Perlite and vermiculite are two different substances used for a common purpose, that is for moisture retention and aeration in soil. That means to hold water within soil for plants and also to improve air circulation or aeration of potting mix. Perlite and vermiculite are quite different in composition and also performance wise."

    First, we know that are used for a similar purpose, or else no one would be comparing them. Second, we know there are differences, or no one would sell two different products.
