Plastic Free

No petroleum-based plastics are used in this product or its packaging. Plastic can be difficult to properly recycle, may never biodegrade, and is known to leech toxic chemicals into our bodies and environment. Single-use plastics also require extracting and processing of finite resources, so seeking out biodegradable, infinitely recyclable, or durable products and packaging is recommended whenever possible.

Compostable Packaging

This product is packaged or shipped in materials that can be composted in home systems or industrial facilities. Certain materials may be better fit for industrial facilities than backyard composting systems. Contact your local waste-hauler or composting facility to determine where these materials may be accepted. Industrial facilities may not exist in your area.

Sustainably Harvested

Some or all of the ingredients or materials used to produce this item have been sustainably harvested. Sustainable practices involve managing land in ways that prevent overharvesting, preserve the natural ecosystems and animal habitats, and ensure a sustainable harvest for the future.


This company donates a portion of their time or profits to charitable efforts in their community or abroad.

Made in the USA

This product was made in the United States. Buying locally made items helps to reduce harmful emissions that result from transportation during and after the production process. Purchasing products made in the United States also ensures that the items are produced in ways that meet strict safety and labor standards.

    Great soil

    Gary (verified owner)

    Got this soil for repotting a few new plants and was pretty impressed, you can tell just by feeling it that it’s high quality. My plants are super happy!

    Worst potting soil

    lauracblum (verified owner)

    This is literally the worst potting soil I’ve ever worked with. Water just sits on the top of the soil and never drains. I had a plant die within days of repotting in this soil. When I pulled it out the roots were bone dry despite multiple attempts at watering it.
