How to tell if wood is too wet for burning?

Assessing the Wood’s Moisture Content

To determine if the wood is too wet for burning, you can use a wood moisture meter. These devices measure the wood’s moisture levels in a few seconds, giving you an accurate reading. Look for a meter that can measure moisture content in a range of 5-40%. Insert the probe into the wood, usually 1-2 inches deep, and wait for the reading. If the reading is above 20%, the wood is likely too wet for burning.

Checking the Wood’s Surface for Signs of Dampness

In addition to using a moisture meter, you can also check the wood’s surface for signs of dampness. Look for white or grayish patches on the wood’s surface, which indicate high moisture levels. Check the wood’s bark, as well. If it’s soft, soggy, or falling off, the wood is likely too wet. Another sign of dampness is a musty or earthy smell. If the wood smells damp, it’s best to avoid burning it.

Using the “Split Test”

Another way to determine if the wood is too wet for burning is to use the “split test.” This involves splitting a small piece of wood in half and examining the interior. If the wood is too wet, it will likely split easily, and you’ll see a high amount of sapwood (the lighter-colored wood) on the inside. If the wood resists splitting, or if you see mostly heartwood (the darker-colored wood), it’s likely dry and ready to burn.
