Many times old fence posts rot from the top; if there is a place for the weather to get in, that’s where it starts.
Eventually, there will be a hole or depression in the very top of the post, and then is pretty much game over, out comes the fence post, and a new one is installed.
Some of these old fence posts are cedar, or other long lived wood, so the rest of the post is still sound and unrotted.
Once they’re out of the ground, they’re fair game for me to make into a unique rustic planter. You may also find something similar when salvaging old barnboards or timbers.
I use these for making into fencepost planters. Cut at about 30cm (1') from the top they are big enough for a few Sedum and Sempervivum, who relish the dry conditions.
These kinds of fencepost planters won’t last long but they pack a lot of impact in the short time before they completely rot away.
This old fencepost planter still has the marks where the barbed wire was attached, giving it an authenticity that is impossible to fake.
Knots, scars and weathering all add to the patina. In a rustic garden, these unique fencepost planters will be a focal point.
