I have lots of bricks and I would like to build a raised vegetable garden from the bricks laying around. I can't find any plans on the internet. I know that I need to dig into the ground, put down some type of cement and put in metal rods that the bricks slide on and then stack the bricks on top of each other. How deep do I dig (about 2-3 ft. tall is goal) for the foundation? What are the medal rods called and what size should I buy? What do I use to lay on top of the bricks since they have the 3 holes in them? I don't want to cement the bricks together once the foundation is built - just slide them onto each other using the metal rods. Help please!!!
 
Rum Corp is right, it is just higher than the ground around it. You can get pieces of re-bar cut 2' long at builders stores to pound into ground for stability after you mortar bricks in place. Place them inside and out side of the walls you're building. That way over time as soil compacts some you'll have extra holding power. Then you fill with good top soil, compost, sand or whatever. If you use the re-bar inside the brick holes, they can rotate katie-whompus all around. And getting enough pieces of re-bar to do this would be quite costly as you'd need at least 2 per brick. Even if by 'brick' you mean 'cinder block' it's still the same answer. Your foundation should be normal yard, grass and all. The green buried plants will add nitrogen to the soil for good vegetable growth. 2' high is plenty.
 
You don't have to use a concrete footing with steel for a small garden retaining wall, you can just use the bricks themselves as the footing , they usually put down a row of brick on edge then lay the bricks onto of them and if you want this wall to bond in some way, you will need to use a mortar.
