Pumice is better for drainage and aeration than perlite due to its unique physical properties. Here are a few reasons why pumice is preferred:
1. Porosity: Pumice has a highly porous structure with numerous interconnected air pockets. This allows water to easily drain through the soil, preventing waterlogging and ensuring proper oxygenation of the roots. Perlite, on the other hand, has a lower porosity and may retain more water.
2. Water retention: While pumice drains water efficiently, it still retains a small amount of moisture within its pores. This helps to provide a balanced level of moisture for plant roots, preventing excessive drying out. Perlite, being less porous, may not retain as much water.
3. Durability: Pumice is a volcanic rock that is highly durable and does not break down easily over time. It maintains its structure and drainage properties for a longer period compared to perlite, which can break down and compact over time, reducing its effectiveness.
4. pH neutrality: Pumice is pH neutral, meaning it does not alter the pH of the soil. This is important for maintaining optimal nutrient availability for plants. Perlite, on the other hand, has a slightly alkaline pH, which may affect the pH balance of the soil.
5. Environmental impact: Pumice is a natural and sustainable resource, while perlite is a mined mineral. Choosing pumice over perlite can be more environmentally friendly overall.
Our pumice is sourced locally and processed entirely by hand meaning more attention is given to detail resulting in a much cleaner product.
