Best Potting Soil Mixes for Healthy Indoor Plants

Potting Soil Mix

If you have plants or plan on starting a garden, then you might’ve been told to use potting soil. Potting soil is important because it contains many ingredients that can deliver essential nutrients to your plants and keep the nutrients around the roots. You will most often use potting soil with containers and the soil can also help drain water so that your plant doesn’t end up overly-saturated.

What to Consider When Buying Potting Soil

There are some factors you must consider when purchasing potting soil, such as where you will be putting the potting soil. If you’re using the potting soil in containers then you need to use a fluffy and lighter potting soil. You’ll also have to check to see if there’s any water retaining treatment in the soil, since this could require you to change up how often you water if it contains those treatments. The weight of the product also matters because heavier potting soils often are not beneficial and likely contain either a lot of sand or water.

We know how complicated the purchasing process can be, which is why we’re giving you a guide.

One of the main issues people have had with this potting mix is that if you purchase online, there’s a chance you could end up with fungus gnats in the bag. Other people have complained of the soil being moldy or molding easily. The potting mix also has an odor to it that a lot of people find to be unappealing. People have found that between the mold and the smell this soil isn’t great for enclosed areas and the smell can linger even after the plants are removed from the area.

While this soil is great for being light-weight and issue people have with it is that there seems to be mold growing on the soil.
