How do diseases take hold in the soil?
For any disease to take hold, three things need to be present: A pathogen (the microorganism that causes the disease) A host (our plants) The right environmental conditions. In the case of soil-borne diseases, the pathogens can remain in the soil for long periods, waiting for the host - our plants - to come along.
How do I check my garden soil for disease pathogens?
There are also field tests you can purchase online or at local garden centers for checking garden soil for disease pathogens. These tests use a scientific system known as the Elisa test and usually require you to mix soil samples or mashed plant matter with different chemicals that react to specific pathogens.
