Most often, the terms “potting soils” and “potting mixes” are used interchangeably. The differences are subtle and important to understand. There is a difference in cost between the two types and your selection will likely be based on what you’re growing.
Potting soil:
- Potting soil is a structured soil, (man-made) it doesn’t have any actual soil in the compound. It’s formulated to provide optimum drainage which is critical when you’re planting in any sort of container (pots, elevated gardens, etc).
- Potting soil provides the basic needs of any plant; it’s a growing medium that will support the plant and provide space for roots to grow well.
- Because potting soil doesn’t contain organic material, you’ll need to incorporate a fertilizing practice into your plant care. The type of fertilizer required will differ by the kind of plant you’re growing.
- Potting soil may include a low ratio of organic fertilizer. The Espoma brand of soils also include mycorrhizal spores that work with a plant’s root system to increase the efficacy and size of a root system.
- Potting soil is perfect for growing flowers, succulents, and houseplants. Some gardeners use it in very large containers because it’s significantly lighter in weight.
Potting mix:
- Potting mixes have been developed because container gardening has grown in popularity. As our homes and outdoor living areas become smaller, we try to maximize the limited space.
- Potting mixes are essentially potting soil with organic matter added. Most often they will have a low-ratio fertilizer and may also include bio-stimulants like mycorrhizal spores.
- Despite the (pretty confusing) similarity to the name “potting soil,” it does not contain any soil. Instead, this mix contains organic substances that help with drainage: peat moss, sphagnum moss, pine bark, and so on. Additional organic material also provides the nutrients that plants need for optimal health and these differences are primarily what make up the higher cost.
- Potting mixes were primarily developed to assist with vegetables and crops being grown in containers. Many cannabis growers also use potting mixes as it tends to yield the best results.

Benefits of Potting Soils and Potting Mixes
To grow and thrive, plants need sunlight, water, oxygen, and food. With container plants, it’s vital to select the type of potting soil that allows optimal drainage and aeration.
The root systems of plants play crucial roles in their health, anchoring them into the soil and absorbing water and nutrients around them. Plant roots perform their duties well—even too well. If too much water is available to them, they’ll continue to absorb it; so, what’s absolutely necessary for plant health (water) can lead to damaged plant health when there’s an overabundance available to absorb in the soil. This can happen through overwatering or poor drainage—or a combination.
Once too much water is absorbed, root rot develops and may be not reversible. So, prevention is the best cure, which includes choosing the proper potting mixes or soils for the plants you’re growing—which facilitates healthy drainage. Also, be sure to plant them in containers with drainage holes and then water them appropriately. Soil should be moist but not wet; try watering once or twice a week during spring and summer and less during the rest of the year. Watch for signs of dried-out soil, as well, because this usually means there isn’t enough moisture for the plant’s roots to absorb.
