Most property lines are marked with rods of rebar that are staked into the ground, but the main problem about them is that they’re hard to see, easy to remove and hard to find, so it makes sense why some people try to find more creative ways on how to mark their land.
I should begin by noting that placing permanent or really any type of marker by yourself is sometimes illegal in some states and countries, not to mention it’s even worse if you end up doing so in a spot where you thought it was your land but actually wasn’t, so make sure to contact your local land surveyor first.
T-posts
I think the best way to mark a property line, or a corner for that matter is with t-posts. They don’t cost too much and are tall, usually about 6 feet (1.83 m) which makes them stick out quite a bit. After installing into the ground, you can spray paint them for more visibility in colors like the classic orange and such.
You can also cover them with PVC piping with a cap in order to make the posts more thick allowing more paint coverage, which’ll obviously make them even easier to see.
To reinforce the whole construction, try placing some rocks around them.
Wooden posts
Really any type of wooden post will suffice as long as it’s at least 6 feet (1.83 m) long, but it’ll work best if the wood is treated to make it last longer.
A thick 4″ x 4″ (10 cm x 10 cm) post would definitely work, although it will definitely cost a lot more than t-posts, not to mention you’ll need to put in more work in order to make them stay in the ground.
Setting the posts permanetly
If people had already tried removing or displacing your old markers in random places you might consider setting the posts in cement, and that should be done in a hole that’s at least 2 feet (61 cm) deep.
Plants
You can even try planting any type of plant you like on your property lines or corners. Trees would also work great, just make sure they do look different especially if you’re going to be doing that in the middle of the woods.
Just build a fence
The best, although definitely the most expensive way to guarantee a pure disclaimer of your own property is by building a fence. That doesn’t always make sense if you have a lot of land, but if you grow livestock and want to put up some fencing, you might just end up shooting two birds with one stone.
