Perlite Sri Lanka - Wilson Garden

What is expanded perlite?

Perlite is a natural volcanic rock. It will expand to a lightweight, porous material when it is heated to high temperatures. This process makes expanded perlite a great choice for use in many industries, including horticulture and construction. There are three types of perlite:

Irregularly shaped or natural perlite: This type of perlite offers the greatest number of surface areas for water retention. Natural perlite does not have smooth edges like expanded perlite does.

Cube-shaped or expanded perlite: As its name suggests, this type of perlite has been expanded into a cube shape with flat edges so it can be used as a growing medium or soil amendment. Expanded perlite has an enormous surface area compared to its weight and volume; it also has very high water retention capacity and excellent compaction qualities.

Spherical or superfine perlite: This type of perlite is similar to expanded perlite except that it has been crushed into tiny particles and sorted by size before being packaged into bags or other containers for sale to consumers at garden centers and nurseries around the country.

What can perlite be used for?

Perlite is composed of silica and is mined from deposits of volcanic ash. The largest deposits of perlite are found in the southwestern United States, Mexico and China. Perlite medium has various uses:

Soil amendment - Perlite can be added to soil to improve drainage and aeration by helping air pockets develop between particles of soil so water can penetrate easily into the ground. It helps reduce topsoil erosion and improves water retention in soil.

Water retention - Perlite is a natural mineral that is used in many applications such as gardening, landscaping and more. Perlite also helps retain moisture because it holds onto liquid like a sponge does water, which helps plants retain moisture during dry spells.

Insulation - Perlite is usually used as insulation material for homes because it provides excellent thermal resistance properties. Expanded perlite is a lightweight, airy material that is also used for a variety of purposes, including filler and soundproofing.

Perlite medium doesn't affect the acidity or alkalinity of your soil mix because it has a neutral pH (7 on the pH scale). Premium perlite does not retain salts like some other materials do, so it's safe for use with fertilizers and water-soluble nutrients.
