The term soilless potting mix refers to a kind of plant soil that does not include any real dirt. If compared to regular garden soil, soilless potting mixes have a mild pH and a greater capacity to oxygenate and retain moisture for your plants. Soilless potting mixes reduce the chances of root rot and compaction because the chunkier ingredients, including bark, perlite, and sand, allow for greater airflow in and around the roots of the plants.
