Will landscape timbers work for a fence post with painted or rubberized bottoms where it goes in the ground ?

I wouldn't use them. Usually when you see them in the store they're warped already. My neighbor's fence was done with landscape timbers and they're rotting/leaning/etc... I know they're double the price but you can't go wrong with pressure treated 4x4s.
That's actually why I asked 4*4's run 11.67 landscape timbers run 1.97. The price difference made me wonder.

I don't see painting or rubberizing the timbers as a long term prevention for rot. If you don't mind replacing the fence posts every few years, you could buy 5 or 6 timbers for every PT 4X4...

A 4x4 is nearly always made from Southern Yellow Pine (premium grade for dimensional lumber); a landscape timber is made from #3 grade SPF (spruce/pine/fir). The same difference as there is between a utility grade 2x4 and the wood trusses are made from. My .02 is spend the extra $ now cause digging post holes sucks.

No disagreement with the advice but here's what I've done. Our fence is only about 100 feet long, and we wanted it to be rustic. So I cut down some Jack Pine trees with about a 6" diameter trunk. Made fence posts out of these, no treatment at all, dug the holes and put them in the ground. The posts last about 5-8 years before rotted to the point when they need to be replaced. And that's what I do, make a new post and put it in the old hole and life goes on. The rails for the fence also are hand split Jack Pine and they last about 8-10 years.

Replacing every part of a fence every 5-8-10 years is not how I'd want to spend my time. Why not treat the jack pine? Seems like time & money well-spent.
They'll only be good for about 5 years untreated. Painting them might buy you an extra year or two.
Got any locust trees available?

All the old farm fences around here are cedar. Cut a tree, limb it, plug it in the ground. I still have many lining the edge of my property, and I don't know how old they are, but I'm sure they're much older than me.

Pete, I've used a couple of them when we just needed some short posts. Worked well.

Looks good Pete, you won't regret it in 5-8-10 years. Not that there's anything wrong with jebatty's system, just not my thing.
Can the pickets touch or do they need a space in between ? I am using 72" tall by 3.5" wide by 1/4" thick pine slats off of pallets as the pickets. I will put up some more pics today.
Thanks again

Assuming they're PT hem/fir: Either, or. Full privacy, but them tight, but they'll shrink a bit as the ACQ dries.
Two warnings:
1. Don't discount the wind load if butting tight. Figure wind load as proportional to slat width / gap width.
2. KD (non-PT) lumber should not be butted tight, as its likely to grow. Most KD lumber is 7-8% MC, and will grow to an ambient closer to 16% outdoors. In this case, I'd gap 3.5" planks at least 1/8".
If you want full privacy with better looks (from both sides) and reduced wind load, consider shadow box. You'll hate painting it, but it looks great.

I don't know what KD and PT lumber are could you explain please ? I am using pine, fire and a few other soft woods that came off the pallets as the slats.

PT = pressure treated
KD = kiln dried
I have no experience building with pallet wood, but would treat it as KD if stored indoors, or just assume its already at equilibrium if stored outdoors.

I'm gonna keep this one going. I'm having a 6' shadow box fence installed next month and was given a choice of cedar or PT posts. Ive thought and thought and still undecided. Posts will be set in concrete within 2" of grade level if that makes a difference. There is no price difference. I will not be living here forever. Maybe another 5-10 years max.
What would you get???
Oh, and besides hiding the piles of wood from my nice new neighbors, here is the main reason for the fence. He hauls splits for me too!

I would use PT for the posts. They will last much longer, especially if set in concrete, and they're a small fraction of the cost of cedar. Since you're doing shadow box, it will be pretty easy to hide the post behind a picket on the pretty side of the fence.
Also, setting posts in concrete is often not the best choice. You're much better off drilling the hole, setting the post, and then compacting modified crushed stone in around it. It will hold the post like concrete, but will keep the post dry. Even better if you drill the hole 6" deeper than necessary, and put 6" of crushed stone in the bottom of the hole before setting the post. Posts set in concrete usually rot off right at the top of the concrete. This will take close to 20 years for PT, but could happen in 5 - 10 years with cedar.

The in ground contact green pt 4*4s will out last you from what I understand. My friend built his home and the foundation is green pt and very very solid. I didn't even bother with cement after seing that.
