Potting soil and soilless mixes are specifically designed for containers, providing better aeration, drainage, and a healthier growth medium for plants.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.Key Takeaways for Container Garden Soil Skip topsoil and garden soil.
