Perlite is a remarkable volcanic glass that has gained significant popularity in gardening and horticulture due to its numerous benefits for soil health and plant growth. This lightweight material is formed by heating natural perlite ore, causing it to expand into small, porous particles that enhance soil structure.
Perlite features a glassy texture with spherical shapes created by its water content, which measures approximately 2-6%. Its unique properties include:

• Low density
• Low thermal conductivity
• Neutral pH
• Incombustibility
• Low hardness
• Excellent absorbability

These characteristics make perlite an essential component in various soil mixes and growing mediums, enhancing the effectiveness of other soil components.

Benefits of Using Perlite in Gardening

1. Improved Aeration: Perlite creates air pockets in the soil, allowing roots to breathe efficiently.
2. Enhanced Drainage: It prevents soil compaction and facilitates excess water drainage, reducing the risk of root rot.
3. Moisture Retention: It retains moisture without becoming soggy, providing plants with a consistent water supply.
4. Longevity: Plants grown in perlite-amended soils tend to thrive longer due to improved nutrient availability.
