How Does White Mold on Firewood Grow When the Wood is Not Properly Seasoned?
Firewood that’s not properly seasoned is a magnet for white mold. So, what exactly happens to create this perfect environment for fungus growth? Let’s break it down:
High Moisture Content
When firewood is unseasoned, it contains a significant amount of moisture. This can be due to the wood’s natural composition or improper storage. As the wood sits, the moisture inside the wood creates an ideal environment for mold growth.
Favorable Conditions
White mold thrives in damp, humid conditions. When your firewood contains excessive moisture, it becomes a cozy spot for mold to sprawl and spread. This is especially true when the wood is stored in airtight containers or covered areas, which can trap moisture.
Perfect Food
Firewood, mainly oak, maple, and beech, contains cellulose, hemicellulose, and lignin, which are rich in nutrients. This makes them a decadent meal for mold spores. As the moisture inside the wood increases, the nutrients become even more accessible, further fueling the growth of white mold.
How Mold Spreads
Mold spores are incredibly resilient and can spread easily through the air, contaminated tools, or even on your clothes and shoes. When firewood is not properly seasoned, the moisture creates a conduit for these spores to enter the wood, where they can begin to grow and spread.
Prevention is Key
To avoid white mold on your firewood, ensure it’s properly seasoned before burning. You can do this by storing the wood in a dry, well-ventilated area and letting it sit for at least six months to a year. Regularly inspect the wood for signs of mold and remove any affected pieces.
