Very few tree species make naturally durable fence posts. Osage-orange, mulberry, black locust, cypress, and some species of cedar are known for the good service they give.
What timber is best for fence posts?
One of the best timber for post and rail fencing is treated pine, as it's incredibly versatile to work with and durable. Used extensively in the building industry in a range of outdoor constructions, you can expect to find treated pine in everything from decks, pergolas to retaining walls and cladding.
You can cut a pine tree into fence posts right after you cut it down. The younger wood near the top of the tree isn't suitable for fence posts, because the nails will fall out of the wood grain. Any part of the tree with a continual diameter of six inches is suitable for making fence posts.
