Planting a young plant


When you use organic potting soil, you can be sure you’re starting with a strong foundation for any container garden. You can also be sure you’re doing your part to be sustainable and support a healthy environment. 

Organic soil is often made up of decomposed, natural materials, which tends to have built-in benefits like having minerals, microorganisms, and other good nutrients. There are no chemicals added or unknown ingredients, promising to make your plants bigger and better. As you start looking for a good organic soil brand, be sure to check out local sources as well. Farms, landscape companies, and local garden centers will often create their own, which you can order by the bag or even in bulk.

For smaller areas and containers, here are some of the best organic potting soil options.

What to Look for in Organic Potting Soil


This is the most important thing to look for when trying to find a good organic potting soil. The product should absolutely list the ingredients in the bag. You might not necessarily recognize every single item listed, but you should be able to pronounce it and get a general sense of what’s inside. If you’re unsure, google it. And if it sounds like something odd, unusual, or potentially chemical-based, it might be best to skip the brand altogether. A lot of times, simple is best. You want to see ingredients like bat guano, manure, and worm castings on there. This indicates natural ingredients, which should be plentiful in organic soil. 


With buying soil, go big! It’s easy to think you’ve bought plenty, and then before you know it, you’re running low but still have four containers to go. Companies tend to list quantity in all different ways, so make sure you’re comparing apples to apples when you’re shopping for soil. It’s easy to see how much you’re getting when you’re in person or at a store, but it’s much harder to figure this out online. Look at the overall weight of units you’re buying to make sure you order enough. 


Look up the company online or on their website. Do they list where their organic materials come from? Not all will, but transparency tends to be a good sign. This alone can be a great indicator of the quality of organic matter, thus the quality of the soil overall. Companies that are certified organic and have a history in the organic gardening community are proud of this. They will often put this information front and center, so be on the lookout for it. 


Look for the purpose of the soil right on the bag. Is it a general potting soil? Is it a concentrated product that should be mixed with general soil? Is it created with something specific in mind like indoor plants, veggies, or even starting seeds? This can make a difference in your overall success, especially if you need potting soil with a specific pH or a different blend overall (more sandy for instance). Read the fine print. 

Frequently Asked Questions
  • Does organic potting soil go bad or expire?

    While some people will recommend keeping potting soil for a limited time, it’s often fine to use it even years after you’ve purchased it. Do the smell and visual test, making sure it doesn’t smell bad and ensuring there are no weird growths or insects that have infested it. If you have potting soil that is a year or two old and it looks (and smells) fine, try mixing it with new soil to stretch your dollar.

  • Can you use organic potting soil in garden beds?

    Yes, you can, though the general rule of thumb is that garden beds should be made up of potting soil, compost, and top soil at a ratio of around 10/30/60. This means a bed made up entirely of potting soil might not be the best mix for your outdoor plants. If you have a large area to fill, look into a good, organic soil source in your area so you can order in bulk. Ordering soil in bulk also has the advantage of cutting down on packaging.

  • Is organic potting soil sterile?

    Having sterile soil is actually a myth and isn’t all that important. It’s pretty much impossible to get an all-sterile soil because there’s so much exposure to microbes happening with soil at all times, even airborne. In fact, many microorganisms are beneficial to soil and plants, so you don't need to worry about getting rid of them. Instead, just focus on getting a good quality, and this should get you going in the right direction.
