Give your soil the ultimate boost with Uncle Bob’s Premium Worm Castings, nature’s most complete and balanced natural fertiliser. Made in New Zealand from carefully managed composting worms, our castings are packed with beneficial microbes, essential nutrients, and organic matter that improve soil structure, enhance water retention, and promote long-term plant health.
Worm castings feed your plants slowly and naturally, encouraging strong root systems, faster seedling growth, earlier flowering, and higher yields — all without the risk of over-fertilising. Safe for all plants, including seedlings, houseplants, vegetables, and ornamentals.
Each batch is produced from high-quality inputs, screened for consistency, and packaged in eco-friendly paper packaging that breaks down naturally. Whether you’re revitalising tired soil or maintaining a thriving garden, our worm castings regenerate the soil, strengthen plants, and support a healthier ecosystem from the ground up.
Planting: Mix into soil before planting for strong starts.
Top dressing: Spread around the base of established plants and water in.
Potted plants: Mix into potting mix or sprinkle on top.
Reapply every 6–8 weeks or as needed.
