Softwoods vs. Hardwoods

These two botanical classifications are confusing because there is no direct correlation between the classification and the hardness or softness of the wood.

• Hardwoods have broad leaves
• Softwoods have needle–like or scale–like leaves

Sapwood & Sap Lines

• Contains living cells and performs an active role in the tree’s life processes
• Located next to cambium
• Functions in sap conduction and storage of food
• Ranges from 1 ½” to 2” thick, thicker in maples, hickories, ashes, some southern yellow pine and ponderosa pine, especially in second growth trees
