Black Swallow Pumice Stone (3/8" X #8-21) is a high-quality, volcanic, porous stone that improves soil structure by enhancing aeration and moisture retention. This horticultural-grade pumice is sourced from Idaho, USA, and is ideal for amending garden soil to improve drainage, reduce soil weight, and promote healthy root development. Its 70% porous structure allows it to hold moisture while ensuring excess water flows through easily, making it perfect for plants that require well-drained yet moisture-retentive soil. Pumice’s neutral buoyancy ensures it won’t sink or float, providing consistent aeration and preventing soil compaction. As an inorganic material, it won’t break down, decompose, or rot, making it a long-lasting, odor-free addition to your garden mix.

Key Features:

  • Aeration & Moisture Retention: The porous structure allows pumice to hold moisture while improving drainage.

  • Durable & Long-Lasting: Won’t break down, decompose, or shrink, ensuring long-term performance.

  • Lightweight & Neutral Buoyancy: Won’t sink or float, maintaining even distribution in soil.

  • Inorganic & Odor-Free: Pumice is a clean, odorless material that improves soil structure without decay.

Benefits:

  • Improves Soil Structure: Adds porosity to soil, promoting better aeration and reducing compaction.

  • Enhances Drainage: Perfect for plants that need well-drained soil but also benefit from moisture retention.

  • Promotes Root Health: Improved aeration and moisture retention support strong, healthy root development.

  • Sustainable & Safe for Organic Gardens: Inorganic material with no decomposition, making it ideal for long-term use in organic gardening.

Application Instructions:

  • For Garden Soil: Mix pumice with garden soil or potting mix at a ratio of 10-20% by volume to improve aeration and moisture retention.

  • For Containers & Raised Beds: Add pumice to your soil mix to improve drainage and reduce soil weight. Apply a layer of pumice at the base of containers for additional drainage.

  • For Hydroponics: Use pumice as a medium for hydroponic growing to promote aeration and moisture retention.

Storage Instructions:
Store in a cool, dry place to maintain product quality and ensure moisture does not affect the pumice.
