A water-retaining sponge for your soil! Vermiculite is prized for its accordion-like structure that allows it to absorb and hold several times its weight in water and nutrients. It then slowly releases this moisture and food back to the roots, providing a consistently moist and stable environment.

Best For:
- Seed Starting: A lightweight, sterile, and moisture-rich medium that encourages rapid germination.
- Rooting Cuttings: Provides the steady moisture and aeration needed for delicate new roots to form.
- Moisture-Loving Plants: Excellent for houseplants or containers that require consistently moist soil.
Key Actionable Steps:
- How to Mix: Blend with peat moss and other components to create a custom, high-moisture potting mix. A common ratio for general use is 1 part Vermiculite to 3 or 4 parts soil.
- Seed Starting: Use 100% Vermiculite or mix with fine-grade starting mix. You can also sprinkle a thin layer on top of newly sown seeds to maintain consistent surface moisture.
- Pro Tip: Moisten the Vermiculite before mixing it into soil or using it to prevent the fine, lightweight flakes from creating irritating dust.
