MGO Worm Castings

Premium Vermicompost for Living Soil, Plant Vigor, and Root Health

MGO Worm Castings are pure, screened vermicompost produced by composting organic matter through the digestive systems of earthworms. The result is a microbe-rich, slow-release fertilizer packed with plant-available nutrients, beneficial bacteria, humic substances, and natural growth hormones. Ideal for all stages of plant growth, worm castings promote root development, seedling resilience, nutrient cycling, and long-term soil structure.

Perfect for use in vegetable beds, seed starting mixes, fruit trees, container gardens, raised beds, and soil restoration projects.

Key Characteristics

  • Feeds Soil Biology and Enhances Nutrient Cycling
    Worm castings contain abundant beneficial microbes and humic acids that stimulate soil life, unlock bound nutrients, and build organic matter. This results in more efficient uptake of nitrogen, phosphorus, potassium, and micronutrients.

  • How to Use in Gardens, Beds, and Potting Mixes

    • Soil mix: Blend 10-20% by volume into potting or seed-starting soil.

    • Topdress: Apply ¼-½ inch layer around plants, then water in.

    • Transplants: Add a handful to each planting hole for root zone inoculation.

    • Compost tea: Brew with 1-2 cups per 5 gallons for microbial-rich foliar or soil drench.

  • Boosts Root Growth, Seedling Health, and Yield
    Natural plant hormones like auxins and cytokinins found in worm castings stimulate vigorous root branching, reduce transplant shock, and promote early and balanced vegetative growth.

  • Ideal for These Crops and Systems

    • Tomatoes, peppers, leafy greens, carrots, and herbs

    • Fruit trees, berries, and perennials

    • Seedlings, nursery starts, and transplant success

    • No-till beds, raised gardens, composting systems, and greenhouse crops

  • Safe, Non-Burning, and Organic-Compatible
    Worm castings are naturally balanced and will never burn plants, making them perfect for delicate seedlings, young transplants, and continuous feeding in living soils.
