Back to the Roots Goes Full Circle with New Mushroom Compost

OAKLAND, CA – March 13, 2026 – In a move that brings its 15-year journey full circle, Back to the Roots, America's fastest-growing organic gardening company, has launched its new Organic Mushroom Compost exclusively at The Home Depot. The product, derived from the same agricultural ecosystem that first inspired the company, marks a significant moment for the Oakland-based brand, which began as an urban mushroom farm in a college fraternity kitchen.

Developed with many of the specialized partners from their early days, this professional-grade soil amendment introduces home gardeners to “spent mushroom substrate,” a long-held secret of the organic farming community. The launch not only expands the company's portfolio but also powerfully reinforces its foundational mission of upcycling and sustainability.

“This product isn't just a new SKU for us; it’s a return to our roots,” said Nikhil Arora and Alejandro Velez, Co-Founders and Co-CEOs of Back to the Roots. “When we were first farming gourmet mushrooms in Oakland, local organic farmers quickly educated us on how incredible this spent substrate was as a soil amendment and we began to have a long wait-list to pick up our ‘waste.’ To now be able to bring that same biological magic of mushroom compost to home gardeners around the country is a really fun opportunity.”

The 'Gold Standard' for Home Gardens

Mushroom compost is often called the “gold standard” by seasoned horticulturists, and for good reason. The material is the nutrient-dense byproduct of the mushroom growing process. As fungi grow, they break down complex organic matter, essentially pre-digesting it into a form that is highly bio-available for plants. This process creates a soil amendment packed with benefits that were once accessible primarily to commercial organic farmers.

Key advantages of using mushroom compost include:

• Superior Soil Structure: It dramatically improves the texture, or tilth, of soil. In heavy clay, it enhances aeration and drainage, while in sandy soils, it helps bind particles together to improve water and nutrient retention.
• Enhanced Water Retention: The compost’s porous, sponge-like nature allows it to hold significant amounts of water, reducing the frequency of watering and making gardens more resilient to dry spells.
• Balanced, Slow-Release Nutrition: It is rich in essential macronutrients and also contains vital trace minerals like calcium, which is crucial for preventing common garden afflictions like blossom end rot in tomatoes and peppers.
• A Boost of Microbial Life: The compost inoculates garden soil with a diverse array of beneficial microorganisms. These microbes help suppress soil-borne diseases, cycle nutrients, and build a robust, healthy soil ecosystem.

This launch taps directly into a rapidly expanding market. The U.S. residential organic compost market was valued at over $400 million in 2024 and is projected to grow at a compound annual growth rate (CAGR) of 8.6%, driven by a surge in home gardening and heightened consumer demand for sustainable, chemical-free food production.

A Sustainable Journey: From Coffee Grounds to Retail Shelves

The story of Back to the Roots is a modern business parable of sustainable innovation. Co-founders Nikhil Arora and Alejandro Velez famously started their venture after learning they could grow gourmet mushrooms on spent coffee grounds, a waste product they collected from local cafes. Their first farm was in a fraternity kitchen, but their vision was always much larger: to reconnect people with their food.

That initial, simple act of upcycling a waste stream into a valuable food product became the company's guiding principle. As they grew their mushroom farm, they discovered another link in the circular economy. Local organic farmers eagerly sought out the “spent mushroom substrate” left over after harvesting, valuing it as a premier soil conditioner. This byproduct, far from being waste, was a key ingredient for regenerative agriculture.

Now, 15 years later, the company has evolved from a niche mushroom kit producer into a national organic gardening powerhouse with over 150 products. Its presence in over 10,000 retail locations, including Lowe's, Target, and Walmart, is a testament to its market penetration. The new mushroom compost, born from the very byproduct that was once a secondary part of their business, represents a powerful and authentic return to the company’s core identity.

The Green Aisle: A Strategic Partnership in a Booming Market

The exclusive partnership with The Home Depot is a strategic masterstroke for both companies. For Back to the Roots, it provides unparalleled access to the American home gardener. For The Home Depot, it solidifies its position as a destination for the growing number of consumers committed to organic and sustainable practices.

This launch deepens a decade-long relationship between the two brands. Home Depot has been actively expanding its organic gardening offerings to meet the demands of an increasingly eco-conscious and health-aware customer base, particularly among Millennial and Gen Z consumers who prioritize sustainability. Exclusive products from trusted, mission-driven brands like Back to the Roots are a key part of this strategy, helping the retail giant differentiate itself in a competitive market.

The organic soil amendments market is no longer a niche category. Globally, it is valued in the billions and continues to show strong growth, with organic products commanding a majority share of the total soil amendments market. By securing an exclusive on a high-demand product like organic mushroom compost from a leading brand, The Home Depot is making a calculated bet on the future of gardening retail.

The Future of Gardening is Upcycled

This product launch is more than just a new item on a store shelf; it is a tangible example of the circular economy at work in a consumer-facing product. It reflects a broader shift in the market where sustainability is not just a marketing buzzword but a core driver of product development and consumer choice. By taking a byproduct of one industry (mushroom farming) and transforming it into a high-value input for another (home gardening), Back to the Roots demonstrates a practical and scalable model for sustainable business.

To serve every type of project, the Back to the Roots Organic Mushroom Compost is being offered in convenient 1-cubic-foot bags in The Home Depot's garden centers, as well as in bulk 60-cubic-foot pallets available for home delivery via the retailer's website. This dual-format approach ensures that everyone from the balcony gardener to the small-scale homesteader can access this professional-grade amendment.

As consumers continue to seek healthier food, more sustainable lifestyles, and a deeper connection to the natural world, products that deliver on performance, value, and mission will lead the way. With its new Organic Mushroom Compost, Back to the Roots is not just selling a bag of soil amendment; it is offering a piece of its history and a powerful tool for gardeners to build healthier soil and a more sustainable future, one garden at a time.
