Can you use landscape timbers for fence posts

I want to build a 50x100 ft area to divide into breeder runs and a large "free range" area that will be use on alternate days. How long would the timbers last? 4x4x8's and 7 1/2ft T-post are $6.00 ea. and the timbers are 8ft. and will only run approx. $3.00 ea. so a huge cost savings but if they wont last then....

For the difference in money, I would use the T post. I haven't seen a termite eat one yet.

My landscape timbers have been up for 8 years now and still going strong, the part in the ground is in concrete.

I don't know what a T-Post is, the only thing that comes to mind when you say T-Post are the metal clothesline posts.

Did you do anything else to the timbers before sinking them in concrete?
My DH thinks they will rot very soon 8yrs and going strong sounds good. They are pressure treated just like the 4x4s . The T-post are what we use to put up cattle fence

T post are fence posts made of metal, they last forever. Google fencing supplies.

No not a thing. I did buy the ones that are pretreated for insects. Here they sell them either as pressure treated or pressure treated and dipped in a insecticide.

I think the fact that I used quickcrete to set them instead of just tamping down dirt protects them from the insects and to some extent wetness. The place I previously lived at the timbers were on their 10th year when I sold the place and no issues.

Installing wood posts with or without concrete is more labor intensive and time consuming than installing the same number of "Tee" posts.

I think the cost of a wood post plus concrete will be pretty close to a "Tee" post.

I would say about 3 years.

I don't know... that's a lot of work, sounds like you'll be putting in 40+ posts. Think about it this way.... would you install all those posts for $3 each for someone else? Cause that's essentially what you will be doing if they fail in 8-10 years and you have to re-do it. Well worse, actually cause you have to re-purchase materials too.

So how long to you actually need it to last?
