Raised garden beds

I've heard from the two camps about treated lumber and both are sure they are correct. I used treated lumber for mine and grow vegetables in them. Proponents usually tell you that the wood does not leach anything of any consequence into the soil. People who don't want you to use treated lumber tend to use the organic gardening reasoning based more on gut feelings. Obviously you have made your choice and I would not try to change your mind.

It would be best, since different areas of the country have different wood species available, if you told us what you have to choose from. Would do you no good if I said that you should use cedar if your local Home Depot does not sell cedar 2x lumber. In my area it's either treated or stud grade lumber. No other choices except kits.

Use cedar wood.

I like cedar

Are you using wood for looks or for expense.. my friend used concrete blocks,holes up and filled with soil, and planted onions and strawberries in the holes in the blocks.. keeps the strawberries out of the dirt,

you can also use the galvanized stock tanks (around $ 90 at our Lowe's for a 2ft tall X 4 ft long X 2 ft deep)... un cork the drain and/or drill holes in the bottom and they work great. Tall enough to not break your back and big enough for lots of stuff. Plus if you ever need to move them around, just dump the dirt out onto a tarp, and they are light enough to pick up and move.

I have a raised vegetable garden and love it. It was made with landscaping timbers. You can drill holes in the timbers at the corners and pound in stakes for sturdiness, We also used L brackets. Also, be sure to lay down weed fabric before you fill it with dirt. I hope you enjoy your new raised bed as much as I do.
