How does mold grow on firewood?

Second, mold needs oxygen. Like every living thing, mold requires oxygen to live, and we have plenty of that everywhere.

Once your firewood gets wet and isn’t properly dried after a day or two, it will develop mold. There are several reasons for water damage on firewood.

One of them is getting rained on. Another is storing them in a place with excessive moisture, like a crawl space or in a basement.

Regardless of the reason, we can conclude that water damage inevitably leads to mold.

Apart from ruining the integrity of your firewood, it can also cause adverse health effects. This is especially the case if you store your wood in your crawl space or basement.
