BLACK GOLD® Natural & Organic Potting Soil

~Written by gardening expert

BG Natural and Organic Potting Soil
Black Gold Natural & Organic Potting Soil is so versatile it works for everything from hanging baskets to raised vegetable beds. This is not just any soil, it’s a precise blend of everything your plants need to look their best and produce abundantly. Because it’s listed by the Organic Materials Review Institute, you can be sure your organic food crops grown in this enriched soil remain blessedly chemical free.

The scientists at Black Gold have worked hard to create the very best combination of organic matter and drainage enhancers. The base is not filled with woody matter like low cost soils which can be notoriously low in nutrients. Ours is strictly created with sphagnum peat moss, compost and finely ground forest products for water retention and overall nutrition. To prevent packing down and ensure perfect drainage, optimal proportions of coarse perlite and pumice are incorporated for a moist, yet aerated root zone.

What really boosts this potting soil is the addition of screened worm castings, which contain a wide range of biological benefits. These byproducts of earthworms contain the very stuff of plant life: microscopic organisms that turn potting soil from a collection of organic matter into a living breathing soil teeming with microbes. Castings are also rich in minerals and micronutrients, which are so often lacking in man-made soils. The combination of organic matter, microbes and nutrients are three most important elements of the organic garden, driving the decomposition process that feeds plants naturally. Many of the microbes can also benefit plant growth, disease resistance and the ability to survive a dry spell.

So don’t buy one soil for your organic garden and another to power your flowers through the season when there’s a single organic product that does it all. The real benefit of such a perfect blend is its longevity, because living soil is literally self sufficient. It rarely requires replacement because this soil doesn’t wear out like cheaper brands that can never be coaxed to produce well the second or third season. Count on Black Gold Natural & Organic Potting Soil to remain fertile and well drained today and years down the road for a clean, chemical-free, sustainable garden.

  2. Karen says:

    I would like to use this to grow blueberries in. What is the PH of this soil?

    • sungrohorticulture says:

      Hi Karen,

      The pH of Black Gold Natural & Organic runs between 5.6 and 6.8. Since blueberries prefer a more acidic soil (usually 4.0 to 5.0 pH), you may want to add some Black Gold Peat Moss, which is also OMRI certified, to bring the pH of your mix down.

      Cheers and Happy Growing!

  3. Jeremy says:

    Are you saying that one should add “bone and feather meal” or that the black gold already contains it?

    • Jessie Keith says:

      Hi Jeremy,

      Great question! This mix does not contain a significant amount of feather meal or bone meal. For general gardening, we suggest adding either Black Gold® All Purpose or Black Gold® Tomato & Vegetable natural and organic fertilizers. Both contain feather and bone meal, among other good things, and are OMRI listed for organic gardening.

      Happy growing!

      • Danny says:

        Actually, Black Gold® All Purpose is not OMRI listed. Were you referring to the Natural & Organic Mix as all purpose with feather and bone meal? btw, Why isn’t the Black Gold® All Purpose Potting Soil classified as organic?

        • Jessie Keith says:

          Good Morning Danny,
          Great questions! Black Gold All Purpose Fertilizer is OMRI Listed but Black Gold All Purpose Potting Soil is not. The comment was referring to the fertilizer. Our technical specialists provided the information regarding the bone meal and feather meal. I will ask them to clarify. I will also find out why Black Gold® All Purpose Potting Soil isn’t classified as organic. More to come!

        • Jessie Keith says:

          Hi Danny,
          According to our technical specialists, Black Gold All Purpose Potting Soil is not OMRI listed because it contains a chemical fertilizer that is not OMRI approved. But the Black Gold fertilizers, Black Gold® All Purpose and Black Gold® Tomato & Vegetable, are OMRI Listed and do contain bone meal and feather meal. Thanks for your comment, and please let us know if you have any more questions about our gardening products.

    I’m new at this hobby, just bought a Pickering mango and looking to buy Negrone fig. Is this a good pooting soil for both?

  5. James says:

    Hi. I want to know if your product is affiliated with Monsanto. I am looking to purchase potting soil that is not. This is important to me and if your product is Monsanto free, I will become a customer.


    • Jessie Keith says:

      Hi James,

      Sun Gro Horticulture is a privately owned company unaffiliated with other companies. Many of our products are OMRI Listed for organic gardening. Happy growing!

  6. Jeff Gardner says:

    Hi! Thank you for this wonderful product! I have been using this religiously for over the years, and I’ve recently started up a YouTube channel and Blog. I garden year round and use your product probably once a month to start my seeds. Thanks for such a wonderful product! I’m always promoting it!

  7. Janis says:


    I would like to grow plants in doors. I want to know the basics of potting and planting seeds. I would like to grow a plant, fruit or vegetable that would be easy to maintain for beginners. What type of organic soil would you suggest?

    Thank you

    Janis ,

  8. Will T. says:


    There are worms found in your bags at Home Depot. I was wondering what type of worms those were.

    • Jessie Keith says:

      Hi Will,

      Our Black Gold Natural & Organic Potting Soil contains worm castings as part of its ingredients. Earthworm castings are the excretions left behind by earthworms after they digest organic matter. Earthworm castings are a terrific soil amendment and natural fertilizer. There are no worms in the product although it is possible there could be eggs as part of the castings. Earthworm castings by itself is considered compost which can be added to any garden or used for a “compost tea”. We sell a separate product, Black Gold Earthworm Castings to be used for these purposes.

      Presently, we don’t sell our products at Home Depot.

      Happy Growing!


  9. Tiffany Field says:

    Hello..currently researching best potting soils for a ‘ budding’ type of plant that really doesn’t like acidity in the soil. Is the black gold top soil very acidic? I tried to plant one of my plants in this and it turned black and died pretty fast. Is this due to the acidity in your product?

    • Jessie Keith says:

      Hi Tiffany,

      Thanks for your question. We do not have a product called Black Gold Topsoil, so we would need a little more information to answer this question. If the product you used is one of our amendments, such as Black Gold Garden Compost Blend, Black Gold Soil Builder, or Black Gold Soil Conditioner, it may burn the plants since it is intended to be mixed into existing garden soil. Most of our potting mixes are formulated to a pH range of 5.8 – 6.5, but again we would need to know the specific product you used to correctly answer your question.

      Happy gardening!

    Is your organic soil good for wheatgrass? Thanks

    Hi, I’m using the Black Gold Natural & Organic Potting Soil and have great results so far with an indoor banana tree..I know, right? Just before the fruit ripens, my routine is to flush the 5 gal containers with plain water at a rate of 3 times per container volume. I may do this at 2 or 3 week intervals. Before I reuse this soil for another banana grow, I am curious to know how much of the organic matter, microbes and nutrients is diminished by the flushing.

    • Jessie Keith says:

      Hi Che,

      We do not recommend reusing any product. The products we sell are designed to be used for one growing season (4 to 6 months). Over that time period, the roots will take up the nutrients offered by the different components in the mix. By the time the crop is matured, or in your case a new banana requires potting, the mix is depleted of any added nutrients. Additionally, as the mix ages its structure breaks down and changes, pH changes, and there could be microorganisms and disease introduced that you would not want the next plant to be exposed to. When it comes to soilless mixes, the best course of action is to start with fresh, quality mix every time.

      Happy growing!
