Why do we burn forests on purpose?
By ridding a forest of dead leaves, tree limbs, and other debris, a prescribed burn can help prevent a destructive wildfire.

How long does a dead tree take to season?
The best wood is typically seasoned for two to three years but will start to deteriorate after four to five years and will not be good to burn. Stack the wood off of the ground and in a way that allows air to circulate and carry away the moisture as it evaporates through both ends of each piece.
