    Best Potting Soil – Buyer’s Guide

    Generally speaking, the best potting soil serves the same purpose of any soil because it works to support your plants and deliver both nutrients and water to the roots. The best potting soils will mimic the plant’s native soil to give it the best growing environment possible. This means that you have to tailor your soil to your plants. For example, you’d use a different soil for desert landscaping than you would for a tropical garden.

    Soil 2 Desert
    Desert landscaping is much different than growing plants in a cooler environment, and you’ll need more nutrients and moisture retention to offset the harsh conditions and lack of water.

    A lot of the commercial potting soil mixes you’ll find on the current market come packed with fertilizer. This can be a quick or slow-release variety. It’s beneficial for the potting soil to contain this as it can encourage your plants to grow. However, it’s very difficult to tell exactly how much fertilizer you’re giving your plant when you add it. If you’re someone who has more sensitive plants and you’d like to have exact measurements, opt for the best potting soil mix without fertilizer. This way, you can manually measure and add the fertilizer separately. If you don’t want to use a chemical fertilizer, you can make your own plant food with things you have around the house.

    How well the potting soil works for your plants is entirely up to you. It’s essential that you make sure your plants have enough water. If you live in an area that gets a lot of drought and hot conditions, your plants are going to push their root systems downward and outward to try and find water. Your potting mix should have something in it that helps retain water like perlite, moss, or horticultural vermiculite.

    Buying Considerations 

    What do you look for when you start searching for your best potting soil? They’re not all equal, and some work far differently than others. This is why you have to have at least an idea of what you want when you start shopping. If not, it’s easy to get the wrong kind.

    Soil 3 Guide
    Both organic and non-organic potting soil can work well for your plants, but it’s important that you pay attention to the nutrients in the mix to ensure your plant has enough to support healthy growth. 


    The first thing you should decide is the type of potting soil you want. You can break the best potting soil down into two broad categories. The first category is the organic potting soil. These are usually much more expensive and heavier than non-organic options. They use organic matter only in their makeup, and this can drive the price up. The second category is the non-organic potting soils. They contain man-made ingredients, but they can lose their nutrient value over time.

    You have to understand what sets these two categories apart. Once you do, you can use the following list to narrow down your choices and compare various versions of the best potting soil until you find the best one to help your plants, trees, vegetables, or shrubs grow.


    First up is the air circulation. Your plants will need a good level of circulation to stay healthy, and any potting mix you look at should be able to guarantee this. Light and fluffy potting soils are one option to seriously consider because they allow for maximum airflow. You also don’t want an extremely dense potting soil mix when it gets wet because this can smother your plant and encourage mold growth.

    Soil 4 Circulation
    Many people forget how important air circulation is to your plants, but it’s essential if you want to stave off root rot or suffocate the roots. An airy soil won’t compress much when you get it wet, and it’ll allow most of the moisture to flow through. 

    Nutrient and Moisture Retention

    It’s essential that the best potting soil can retain both essential nutrients and moisture because they’re vital to your plant’s continued health. Before you pick out an organic or non-organic mix, check and see if it guarantees that it’ll retain both of these items. You can find this out by reading the ingredient list on the package. In a non-organic mix, you’ll want to see peat moss listed. The more peat moss in the formula, the better it’ll be at retaining nutrients and moisture.

    Variety of Nutrients

    As a rule of thumb, you want to make a habit of never purchasing a potting soil mix until you’ve taken a few minutes to read the ingredient list. The best potting soil should have much more than a single nutrient in it because your plants need more than one type to survive. The more nutrients it lists, the better your plants are. It’s common to see 6 to 12 nutrients advertised on the bag.


    How dense the best potting soil mix is is very important. If you can, test the density before you buy it. You can do this by poking the soil with your fingers. If it gives slightly, it should be acceptable for your plants. If not, find something else. When you add water, your potting soil shouldn’t get hard. If it does, your plants will shove their roots up through the soil. Another way to check the density is to lift up the bag. If it’s surprisingly heavy, you’re most likely getting a lot of fillers like mulch or sand. This isn’t good for healthy plant growth.

    Soil 5 Density
    It’s worth it to tailor the best potting soil to the type of plants, location, and environmental conditions you have because this can encourage your plants to grow strong while resisting infestations. 

    Bottom Line

    Picking out the best potting soil takes time and a little research. If you get it right, your plants have a much better chance of growing lush and strong all season. You have a buyer’s guide and 10 high-quality options to compare in this article, and you should see a difference in your plants when you use them.
