I was just a little disappointed that I did not fine any worms in my bag seeing as alot of the reviews mentioned finding live worms in thier bags. Was really looking forward to that. But overall still a pretty good product. Happy with the results my plants are getting even in this hot summer and constant watering. ## Frequently Bought Together - Brut Organic Worm Castings – 5 LB – Natural Nutrients, Fertility Builder, Plant Food for Potting Soil, Garden Soil, Indoor and Outdoor Use - Back to the Roots Organic Coir, 51 Quart Expanding Soil, Great for Seeds and Potting - 10QT Horticultural Perlite Bulk, Organic Perlite for Plants, Course Perlite for Gardening, for Plants Indoor, for Houseplants, to Promotes Soil Root Growth, and Water Drainage and Plant Growth(3-6mm) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/679609133-brut-worm-farms-worm-castings-soil-builder-5-pounds-organic](https://www.desertcart.jp/products/679609133-brut-worm-farms-worm-castings-soil-builder-5-pounds-organic) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
