Stack logs so the air can get to them. If you cut and split your logs, try to do it when the wood is fresh cut (sometimes called green), as it’s much easier on you and your tools.
Once split, you have significantly increased the surface area of each piece, and it will dry much faster. Logs need to be properly stacked, not heaped in a pile. The best situation is a well-ventilated log store with open sides and a roof.
If your logs are the right size and properly stored, you should be able to achieve a moisture content of 20% or less in 6 to 12 months. Beware of the word seasoned; it means nothing in reality. The only important consideration is the moisture content.
A moisture meter is a handy tool. Aim for 20% moisture or less. However, for optimum burning, do not allow the moisture content to fall below 11%. To test the moisture content of any log, split it first and then test the split surface.
