How long to season Alder firewood?

Seasoning refers to the drying process of firewood, and it makes it easier to burn the firewood. Seasoned firewood produces less smoke and ash in comparison to wet firewood. Ideal seasoned firewood has a moisture content of 10 to 20%. Alder firewood takes around a season or 6 to 8 months for drying up.

Splitting the alder before seasoning can fasten up the process. Bark on the log prevents the evaporation of moisture content in the wood. So, it is better to remove the bark before seasoning.

Make sure to keep it away from the ground as it will decay the wood. Cover the wood stacks with plastic sheet or tarpaulin if you live in a humid place. This will help in keeping away the moisture.

You can check for the cracks to judge if the wood has been seasoned properly. Perfectly seasoned wood has a darker tone of color. In case you haven’t removed the bark, then it will start losing on its own after seasoning.

You can also cut a piece of wood and check the smell to know if it has dried properly. A block of dried wood is less smelly than wet wood.

You can also crack the pieces of wood and hit them together. If it sounds hollow, then the wood has dried up. Dried wood is also lighter than greenwood. If you are still not sure, then you can fire a small piece of wood to check. Wet wood takes a lot of time to light and produces smoke.

You might want to look into a moisture meter to test the moisture content before you burn it. You can find them on Amazon for a decent price. Here is a link to the one I have. Moisture Meter (Link To Amazon).
