Calcined clay refers to kaolin clay that has been exposed to extremely high temperatures, resulting in a decrease in volume. This heat treatment results in a lightweight, porous material that's largely free of dust and resists compaction. This makes it an effective substrate for various horticultural applications. There are many benefits of using calcined clay for bonsais, house plants, succulents, and cacti:

Improved Drainage: Calcined clay helps enhance soil drainage by creating pore spaces in the growing medium. This prevents waterlogging and allows excess water to drain quickly, reducing the risk of root rot and other moisture-related issues commonly faced by these plants.

Aeration and Oxygenation: By incorporating calcined clay into the soil or potting mix, you improve aeration and oxygenation around the roots. This promotes root respiration and supports healthy root development, leading to overall plant vitality.

Water Regulation: For bonsais, house plants, succulents, and cacti, it is important to regulate water availability. Calcined clay can help with water regulation by absorbing and retaining moisture in the root zone. It acts as a reservoir, providing a buffer against both overwatering and underwatering.

Nutrient Retention: Calcined clay has the ability to retain nutrients in the soil or potting mix. This helps prevent nutrient leaching, ensuring that the plants have access to essential nutrients over an extended period. It enhances nutrient availability and uptake, supporting healthy growth.

pH Balance: Calcined clay has a neutral pH, which can help buffer the acidity or alkalinity of the soil or potting mix. This is particularly beneficial for plants with specific pH preferences, as it contributes to maintaining a suitable growing environment. 

Soil Structure Improvement: Incorporating calcined clay into the growing medium improves soil structure. It prevents compaction and helps create a well-draining environment, promoting root development and preventing soil erosion.

Disease Prevention: By improving drainage and reducing excessive moisture, calcined clay helps prevent the occurrence of soil-borne diseases such as root rot. It creates a less favorable environment for pathogens, contributing to the overall health of bonsais, house plants, succulents, and cacti.

Longevity: Calcined clay is a durable material that maintains its structure over time. It does not break down easily or decompose, providing long-lasting benefits to plants.

When using calcined clay for bonsais, house plants, succulents, and cacti, it's important to consider the specific needs of each plant species. Adjusting the ratios of calcined clay in the growing medium and monitoring watering practices accordingly will help create an optimal environment for healthy plant growth.
