Make Your Own Organic Potting Soil
If you make your own organic potting mix, you still have to avoid using any prohibited ingredients, and that means checking out all the individual ingredients for their organic acceptability.
It may surprise you to learn that products like peat moss or limestone are sometimes treated with prohibited materials such as wetting or anti-caking agents, so don’t rely on assumptions about purity.
In addition to meeting certification requirements, your final product will also need to provide plant roots with the right amount of air, water and nutrients.
