The Soil King

What The Soil King does

The Soil King is a privately held, founder-led organic soil and cultivation-supply company founded in 2005 and headquartered at 320 Santana Drive, Cloverdale, California. It manufactures and sells CDFA-certified organic soils, composts, fertilizers, and amendments under proprietary brands including Big Rootz Soil®, Baby Rootz Seedling Mix®, King Kashi™ (probiotic living compost and bokashi), Finish Line™ (organic finisher/hardener), and Magic Flower™ (bud finisher, natural pesticide, ripening spray). The company also distributes complementary third-party brands such as Mr. B's Green Trees CDFA/organic fertilizers and Azospirillum bacteria inoculants, plus cultivation equipment (Original 420 Brand DeBudder, Skinny Piranha Porta Bucker), functioning as a curated specialty storefront for organic growers.

The underlying product technology centers on certified-organic soil blends and living-compost/probiotic formulations (bokashi fermentation, Azospirillum bacteria) that supply beneficial microorganisms for plant nutrition, with third-party lab verification for heavy metals and pesticide absence to support growers who require certified-input documentation. Commerce is delivered through a Shopify-powered direct-to-consumer store at thesoilking.com, supplemented by a wholesale/reseller program and a content/marketing footprint spanning a blog, the 'Built-4-This' podcast, Facebook, Instagram, and YouTube. The business operates on a one-time unit-pricing model with products priced roughly $12.99–$3,999 USD, ships only within the Continental United States, and shows no external funding, parent company, or public-market activity.

Direct peers

• Roots Organics: Organic growing media and nutrient brand distributed through Aurora Cannabis-adjacent retail channels. Comparable product mix (potting soils, dry amendments, liquid nutrients) and similar cultivation-customer base.
• FoxFarm Soil & Fertilizer Company: One of the most recognized organic soil and fertilizer brands in the U.S. cultivation market, with a comparable DTC and retail footprint across soils, composts, and liquid nutrients. Closest direct competitor to The Soil King's Big Rootz / King Kashi lines.
• Coast of Maine Organic Products: Manufacturer of certified-organic composts, soils, and mulches sold through garden centers and DTC channels. Comparable as a CDFA-style organic-input specialist targeting the same home-grower and small-cultivator segments.
• Dr. Earth: Organic fertilizer and soil amendment brand offering probiotics, composts, and dry amendments. Overlaps directly with The Soil King's probiotic / living-compost positioning and organic certification emphasis.
• Down to Earth Fertilizers: Manufacturer of natural and organic fertilizers and soil amendments sold wholesale and direct. Directly comparable product categories (dry amendments, composts) and overlapping customer base of organic growers.
• Malibu Compost: Premium organic compost and bokashi producer focused on home growers and small farms. Directly comparable on living compost / bokashi product positioning to The Soil King's King Kashi™ line.

Emerging players

• Biobizz: Organic nutrients and growing media brand with strong international presence and a focused organic/eco positioning. Comparable product philosophy (organic, living-soil) but operates at larger scale and with broader geographic reach.

Broad incumbents

• Advanced Nutrients: Large-scale manufacturer of hydroponic and organic nutrients serving cultivation markets globally. Comparable end-customer (commercial and hobbyist growers) but operates as a much broader portfolio incumbent rather than a soil specialist.
• General Hydroponics / General Organics: Established cultivation-input brand with a dedicated organic sub-line. Comparable organic soils and amendments portfolio, but backed by significantly larger distribution and marketing scale.
• Espoma Organic: Long-established organic lawn and garden brand (composts, soils, fertilizers) sold through mass-market retail. Comparable organic-soil product line and home-grower customer base, but at meaningfully larger scale and broader distribution.
