Wood that is not being used should be kept in a dry environment, such as a shed. This will preserve the wood and prevent it from decaying or getting infested with bugs. You should check your wood regularly to make sure there are no problem signs of decay or pests. If you plan on storing your wood for an extended period, using a wood preservative is best to ensure its longevity. The best way to store firewood is by stacking it off the ground in a well-ventilated area and covering it with plastic or tarpaulin.
