I'm curious about the proper depth for growing vegetables, as well as the best materials to use, lumber vs. blocks, etc. We have plenty of space available.
I would KILL for all raised beds. IMHO, it’s the way to go. Husband won’t relent because he just likes plowing it all up in the spring to be done with it.
The only thing to AVOID is those railroad ties soaked in creosote. That can leach into your food. Treated lunber is a no-no, too, to most people. Ick.
It’s really pretty easy. Here’s an idea using lumber:

You could use similar dimensions with stacked cinder blocks, too.
