Know About Reusing Potting Soil – Save A Bunch Of Money




It is very normal for both beginner and avid gardeners to want to make gardening as easy as possible and to save some money on supplies, which leads many people to wonder about the safety and process of reusing potting soil. Whether you are transplanting plants, up-potting to a larger pot, or simply dividing a large plant into smaller ones, you need to make sure that you have quality soil for them.

When you know more about your potting soil and if you can safely reuse it without harming your plants, then you’ll be better prepared for working with your plants.




Can You Reuse Your Old Potting Soil?

The short answer is “Yes,” you can reuse your old potting soil, but we found that there is a lot more to this answer. Because your potting soil is the growing medium for your plants, you want to make sure that they will have a healthy environment that will help them grow as much as possible.

The experts at HGTV address this and say that there are a few things that you need to consider before reusing the potting soil you had in an old pot with a newer plant. If the plant suffered from a disease while potted in the dirt, then chances are very good that the pathogens are still living in the dirt itself.



These pathogens, such as bacteria, fungi, and viruses, can actually sicken your new plant and cause it to die, according to DenGarden. Additionally, your old potting soil may not have all of the nutrients and minerals that your plants need to thrive, potentially causing them to suffer and die.
