In comparison with standard potting
soil, a potting mix is usually lighter, drains away water more effectively, and allows for better air circulation leading to good plants’ root development. Conversely, it lacks microbes and fungi that can be harmful hence not actual soil but should be replaced after using it for some time.
You can always improve your plant’s health by applying new potting mix, such as black gold natural & organic potting soil or soil pep, which you can easily buy, while avoiding disease transmission. It is advisable to regularly monitor the condition of your potting mixes so as to replace them whenever they begin to give way.
