Pumice - 2 Quarts

Give your plants the foundation they need to thrive with Sol Soils Pumice, a premium, lightweight volcanic soil amendment designed to improve drainage, aeration, and moisture management in a wide variety of potting mixes.

Made from 100% naturally occurring volcanic rock, pumice features a porous structure that absorbs and retains moisture and nutrients during watering, gradually releasing them back into the growing medium. Think of these tiny volcanic rocks as little batteries for your plants, helping create a balanced growing environment that supports healthy root development.

Carefully screened to a consistent 1/4-inch to 3/8-inch particle size and dried before packaging, Sol Soils Pumice offers a clean, chunky texture with reduced excess dust and fine particles.

Perfect for cacti, succulents, tropical houseplants, and custom soil blends, this versatile amendment helps create the well-draining, breathable growing medium your plants need.

Ingredients

100% Natural Pumice

A lightweight, porous volcanic rock screened to approximately 1/4-inch to 3/8-inch and dried before packaging.

How to Use

Method 1: Improve Drainage & Aeration

Blend Pumice into your preferred potting mix to create a lighter, more breathable growing medium.

Its porous structure helps improve drainage while maintaining air spaces around the root system.

Method 2: Customize Your Potting Mix

Adjust the amount of pumice based on your plant's growing requirements.

• Cacti & Succulents: Incorporate a higher proportion of pumice for a grittier, faster-draining growing medium.

• Tropical Houseplants & Aroids: Mix with organic potting materials to improve drainage and aeration while maintaining appropriate moisture retention.

• Moisture-Loving Plants: Use a smaller proportion to improve soil structure without making the growing medium excessively fast-draining.

Method 3: Decorative Top Dressing

Spread a layer of pumice over the surface of your potting mix for a clean, natural, volcanic-stone appearance.

Method 4: Drainage Layer

Pumice can also be used as a lightweight layer at the bottom of decorative planting arrangements. For conventional soil-filled pots, always use containers with drainage holes, as a rock layer alone does not prevent waterlogging.

Why Choose Pumice?

Unlike some lightweight soil amendments, pumice combines a durable, porous structure with the ability to retain moisture and dissolved nutrients.

Its natural volcanic composition helps maintain air spaces throughout the growing medium while supporting balanced moisture management.

Sol Soils takes additional care by screening and drying its pumice before packaging, providing a more consistent texture with fewer unwanted fine particles.

Whether you're creating a custom succulent mix, improving drainage for tropical houseplants, or adding structure to an existing potting medium, pumice is a versatile addition to your plant care collection.
