Pumice – durable mineral structure for custom substrates

Pumice gives a substrate stable pore space without making it as light as a perlite-heavy mix. It is a good ingredient for growers who need structure that lasts.

What you’ll notice

• Porous mineral: holds small amounts of water inside hard granules
• Added weight: helps stabilise pots
• Long-term structure: breaks down slowly over time
• Reusable potential: can be cleaned and reused where appropriate

Watering behaviour

The granules hold some moisture internally while keeping the mix open. That makes pumice useful in succulent, bonsai, aroid and semi-mineral recipes.

When to blend it

A pure mineral pot is not right for every houseplant. Use coir, soil or bark where roots need more contact and nutrient-holding capacity.

How to use Pumice

• Stable structure: Adds long-term air pockets and weight to custom substrates.
• Drainage balance: Helps mixes drain without turning bone-dry immediately.
• Mixing: Combine with bark and a moisture buffer for most tropical plants.

Prep and handling for Pumice

• Rinse: A quick rinse removes fines so water moves evenly through the mix.
