Perlite

Perlite is a lightweight, naturally occurring volcanic glass that, when heated to high temperatures, expands into a white, lightweight, and porous material. It is commonly used in gardening and horticulture for various purposes due to its excellent aeration and drainage properties. Here are some key aspects of perlite:

Characteristics and Properties:
Lightweight: Perlite is extremely light, making it an ideal component for creating well-draining potting mixes. It helps prevent soil compaction, allowing roots to access air and nutrients more easily.

Porous Structure: The expanded perlite has a porous structure with numerous tiny cavities. This provides a large surface area for water retention while allowing excess water to drain quickly, promoting a balanced soil moisture level.

Inert: Perlite is pH-neutral and does not contribute to changes in soil pH. It is inert and does not provide nutrients to plants. This makes it suitable for a wide range of plants with different pH preferences.

Insulating Properties: Perlite has insulating properties, which can be beneficial in controlling soil temperature. It helps keep the root zone cooler in warm climates and provides a degree of insulation in colder temperatures.

Sterile and Disease-Free: Perlite is sterile and free of pests and diseases. This makes it a clean and safe option for starting seeds, rooting cuttings, and growing plants in containers.
