When our plants are stressed, we are stressed. Yellowing leaves, brown spots, withering stems, and funny smells are only a few signs that tell us that something is off with our beloved plants. While our minds tend to jump straight to disease, there are a number of other causes for leaf issues. Once you have eliminated water, humidity, pests, and lighting as potential causes, you can then turn to plant diseases.
As humans, we are constantly in contact with good and bad germs that can become a problem when our immune systems or natural defenses are down. Plants function in a similar way. The world is full of microscopic bacteria, fungi, and viruses that only need an excuse to enter the plant and cause issues.
