I'm building the wife an herb garden using landscape timbers but I'm having a problem deciding on how to anchor them down so that the wall will be strong enough. My 2 ideas are 1) dig footings every say 4ft. with a piece of all thread stuck in the conrete so I can bolt them in place or 2) plant a few posts on the inside and lag bolt the timbers to the post.
My wife says I'm way over thinking this but I don't plan on doing this more than once. So any other ideas are welcome.
By the way I'm thinking I'll probably stack them about 3 high.

BillH, is your to-become, herb bed on the bank of a hill? Creating a immobile berm does make for a needed substantial footing.
3 What? Three feet tall? Three beds stacked? I'm missing your intent.
When I have had beds dedicated to just herbs I ran with a couple that got mostly sun & tended to have sandy soil, and others in part or full shade that had more organic material in the soil.
I don't think I ever met a raised bed I didn't like; from the least formal, pudgy soil un-edged beds to, too tall boxed beds.
As far as permanence goes There is a forum here on gardening with disabilities you might want to peek in on. Any raised bed with a planned obsolescence greater than about five years, your probably really talking about masonry construction.

Sorry coppice...I'm putting the bed on a flat piece of what used to be a gravel parking spot on the drive, thats why I'm boxing it in so I can bring some black dirt in and build the soil into something that will grow the herbs. I'm thinking build the wall 3 timbers high. I was thinking of concrete blocks but the Mrs. likes wood and this is hers after I get it built

Eight inches tall will do. The fines of a gravel drive will separate and blend slowly with the compost and humus-y stuff of a raised bed. If you think the ties will float apart, drill the timbers and drive some rebar through the holes. By year four or five your topsoil will run more than a shovel deep of the old driveway surface. Manure goes on top and worms will put it where they want it
