Vermiculite is a naturally occurring mineral that expands into a soft, absorbent, and lightweight material when heated—making it a favorite among gardeners for improving water retention and root development. Supplied in a convenient 3-litre bag, this Vermiculite is ideal for seed starting, potting mixes, and soil conditioning, especially in situations where consistent moisture is key.

Golden-beige and flaky in appearance, Vermiculite has a unique ability to hold water and slowly release it as plants need it, reducing the risk of underwatering and helping to maintain steady hydration around delicate roots. It also gently aerates the soil, creating a loose structure that promotes healthy root growth and reduces compaction.

Perfect for germinating seeds, rooting cuttings, or blending into your favorite potting mix, Vermiculite is particularly useful in indoor gardening, raised beds, and container planting where moisture control can be a challenge. It’s clean, sterile, and pH-neutral, making it suitable for a wide variety of plant types—from vegetables and herbs to houseplants and ornamentals.

Unlike organic materials that break down over time, Vermiculite is long-lasting and stable, offering ongoing benefits throughout the growing season. It pairs beautifully with other substrates like coco coir, compost, or perlite, giving you flexibility to create the ideal environment for your plants’ specific needs.

Whether you’re a beginner nurturing your first seedlings or an experienced grower refining your soil blends, this 3L bag of Vermiculite is a practical, effective, and environmentally friendly addition to your gardening toolkit.
