Firewood can go bad by starting to decompose and rotting away in a process that can take 5 years. It may be no good if has these properties:
2. Hollow sound
7. Has insects
8. Has black fungus
Firewood can decompose and grow mold if not stored properly. Even though age is a secondary property, the right storage conditions are essential for preservation.
To avoid this, ensure that you store your firewood in the right conditions, sheltered from moisture and off the ground.
It takes a year for it to be seasoned. Try to use it in the next 3 years for best results. After that it slowly decomposes.
Usually the problem with firewood is it is too green, rather than too old.
You can still burn rotten firewood, but it may smell. It goes bad slowly, so if parts are bad it may burn fine. Also rotten wood makes less heat.
Does Firewood Need to be Seasoned?
All types of woods need to be seasoned before they can be used. Seasoned firewood has been dried thoroughly after waiting for a proper amount of time, and sometimes it takes up to 12 months for wood to be fully seasoned.
It’s not easy to use too wet wood since the fire wouldn’t end up lighting completely. If you had intended to use the firewood as the source of heat, then you could end up getting easily frustrated.
Does Firewood Absorb Rain?
Firewood will absorb rain, especially after long-term exposure. Wood materials usually have barks for insulation purposes. This may prevent the absorption of rainwater, but only when the amount of small. High rainfall capacity will oversaturate the bark, and the wood will eventually reabsorb water into its system.
Will Seasoned or Kiln-Dried Wood Absorb Rain?
The process of seasoning or kiln-drying wood is lengthy and expensive. But if you don’t store your firewood properly, it doesn’t matter if it was seasoned or not since the prolonged moisture exposure will make the wood reabsorb its water supply. This will eventually increase the chances of your firewood going bad, especially if it’s exposed to rainwater routinely.
But you can dry your firewood after it has been rained on by:
Keeping it in a well-ventilated space with a cover over it
Placing the wood on a dry raised surface or platform. The surface should be free of moisture content.
Expose your firewood to the sun and wind.
