Why is Mold Growing in My Home?

In a natural environment, mold is part of the nature’s cyclical process. Mold works to break down organic material, which is great if you are creating homemade organic mulch for your garden. However, in your home, this is not necessarily a good thing. Mold reproduces by microscopic airborne spores. When these spores blow into the house and land on dusty surfaces or organic material (wood, paper, fiber, clothe, etc.), they continue to cultivate. Warm moist areas are best at culturing mold, but any form of moisture will work.

Wet conditions favor the development of fungal blights of tomato. Mold is everywhere.
