Lightweight Expanded Shale for Better Drainage, Airflow, and Stronger Roots

Give your plants the aeration and drainage they crave with Expanded Shale, a sustainable and versatile soil amendment ideal for bonsai, cacti, succulents, tropicals, and landscape use.

Fired at high temperatures, expanded shale is a porous, lightweight material that resists compaction and improves soil structure over time. Its stable, inert nature makes it perfect for increasing oxygen flow to the root zone while holding just enough moisture to support healthy plant growth.

Key Benefits:

  • Enhances drainage in heavy or compacted soils

  • Boosts aeration and root development

  • Long-lasting, won’t break down or decompose

  • Ideal for use in custom soil blends or as a decorative, functional top dressing

  • pH neutral and chemically inert

  • 1/4 inch particle size

Suggested Uses:

Mix into your potting blend to create a well-draining soil structure, or apply as a top dressing to improve moisture retention, prevent soil compaction, and achieve a clean, finished look.
