Premium Vermiculite

Moisture Retention • Root Support • Soil Conditioning

This horticultural-grade vermiculite is made from compressed mineral flakes that are expanded under intense heat, creating lightweight, accordion-like particles with a high water-holding capacity. The expanded structure retains moisture, air, and nutrients, releasing them gradually as plants need them—making it ideal for plants that prefer consistently damp soil.

Sterile, odorless, and certified asbestos-free, this premium vermiculite is a valuable addition to seed starting, cutting propagation, and custom soil mixes for moisture-loving plants.


🌿 Benefits

  • Holds water and nutrients, releasing them slowly to the roots

  • Lightens heavy soils and improves aeration

  • Provides gentle anchorage for delicate root systems

  • Supports healthy root growth and seedling development

  • Completely sterile, odorless, and non-toxic

  • 100% asbestos-free and safe for horticultural use


🌱 How to Use

  • Soil & Potting Mixes – Blend with peat, coir, compost, or perlite to create a light, moisture-retentive mix

  • Cutting Propagation – Fill a container with moist vermiculite and insert cuttings up to the node

  • Bulb & Root Crop Storage – Loosely pack around bulbs or roots in a ventilated box to absorb excess moisture

⚠️ Wear a mask when handling dry vermiculite to avoid inhaling fine particles.
