Vermiculite vs perlite reddit

If you are standing in the gardening center, trying to figure out which additive your soil needs the most, wondering what the difference is between perlite and vermiculite, then this article is for you.

Read on to learn more about these two all-natural soil amendments that gardeners use to change the water retention and nutrient retention levels in their garden soil.

Perlite is made from volcanic rock, which is heated and crushed until it explodes in order to transform the rock into small white pieces. It has medium water retention ratings and low nutrient retention ratings. It is added to soil mixes in order to improve the drainage capability of both soil-based and soilless potting mixes.

Perlite is lightweight, odorless, clean, and easy to handle. Add perlite to your soil for plants which need their soil to dry out between waterings, such as cacti or succulents. Vermiculite is magnesium-aluminum-iron silicate. It is an all-natural mineral product that is mined out of the ground and then processed into a soil additive that mainly increases water retention and nutrient retention levels in soil.

It looks similar to mica with its layers or stacks, which are suited for trapping water. It has high water retention and high nutrient retention levels. Contrary to rumor, vermiculite does not contain asbestos and it is not a type of asbestos. This rumor is due to some vermiculite that happened to be contaminated with asbestos in a mine in Libby, Montana, which was closed in due to the contamination.

Vermiculite from other sources has since been tested and proven to be asbestos free and harmless. The medium is considered safe for commercial and personal use. Vermiculite is best used for water-loving plants that need their soil to stay moist at all times.

Both mediums are used as an ingredient in soilless potting mixes that are made for the cultivation of plants as well as for seed germination, propagation, hydroponics, containers, and transplants.

They are both also commonly used as carriers in dry fertilizers, pesticides, and herbicides to improve coverage. Both perlite and vermiculite are put to use in the garden to improve drainage, prevent compacted soil and increase moisture retention.
