How to Use Live Trees for Fence Posts

Gail Delaney

Using live trees for fence posts is an economical way to keep animals and people from coming onto your property. Because trees are rooted into the ground, they cannot easily be knocked over by snow, wind or animals. A live tree also lasts longer than a wooden fence post, because termites do not attack it and it does not rot while it is alive.

Live trees can strengthen a fence line.

Step 1

Choose a tree that forms a callus in a short time. This will help protect the tree from disease and insects. Over 57 species of trees can be used as live fence posts, including Gliricidia sepium, Erythrina spp., Spondias spp. and Bursera simarouba.

Step 2

Measure the distance between trees. If it is more than 20 to 25 feet, you will need to dig a hole for a metal or wooden fence post. You may also choose to plant a tree close to that same area so it becomes a natural part of the fence line as it grows.

Step 3

Staple the wire to the starting post or tree. Pull the wire tight, then staple the wire to the next live tree using about six fence staples or 12 roofing nails. This will hold the wire securely and not harm the tree. Continue this process for every tree you will be using as fence post.
