Deer Fence Posts


Distances between Posts

As a general rule, posts should be spaced 20 feet apart to support polypropylene deer fencing and 15 feet apart to support metal hexagrid or welded wire deer fencing. There are exceptions (as when trees are being used as posts, see below), and the distances involved should not be regarded as iron-clad. For instance, if a side of your metal hexagrid fence is 32 feet long, use 1 post in the middle rather than two unless you anticipate severe strains on the fence.

Using Trees as Posts

Trees make the best supports, because they are both strong and natural. When you set up a deer control fence you want to keep things looking as natural as possible, so that the fencing fades into near-invisibility for both deer and people. Trees are admirably suited to this purpose, and if the fence zig-zags a bit as it goes from tree to tree, so much the better.

Trees are also the best supports because they are strong, durable, and well-anchored. Select only healthy trees that have bare trunks, or at least no major branches from the ground up to the top of the fence (usually seven feet) on that side of the tree facing outward toward the deer.

Polypropylene deer fencing, which is light, can run as much as 30 feet (in extreme cases) from one tree to the next with no intermediate support, though 20 feet is the distance recommended. Our metal hexagrid deer fencing (and also welded wire fencing) is heavier than polypropylene fencing and needs to be supported every 15 feet. So if you are setting the metal fence into a place where two trees are, say, 30 feet apart, you can attach the fence to the two trees and then come back and set up a support post halfway between them.

Attach metal hexagrid, welded wire, and polypropylene fencing to trees on the outer side of the trees (the side facing the deer). Do this loosely with U-nails, using no more U-nails than necessary–something like 5 per tree. Be sure (this is very important, unless you are using elk of welded wire fencing) to leave a flap of fencing at the bottom of the fence on the ground, extending outward toward the deer. This flap should be 6 inches long, which means that a 90-inch (7.5 foot) section of fencing will yield a deer control fence with a final (finished) height of approximately 7 feet. If a hole, ditch, or dip causes a flap-consuming space to appear under the fence, you can simply add a piece of cut fencing to the bottom, attaching it to the rest of the fencing with zip-ties and staking it down appropriately.
