| I'm not sure where you're located but wood treated with CCA's are now prohibited in the states. This affects wood that has been treated with arsenic not the newer wood that's been treated with a new copper-based preservative. This change went into effect on 1/1/04.

I have 4 raised beds in my yard, made from wood boards. They were here when we bought our house so I don't know how old they are, but 2 are older & starting to rot. This year, I want to put cinder blocks around them. They would be higher than the existing wood, would last longer, and cinder blocks are fairly cheap. I would like to plant marigolds in the holes of the blocks. (Do marigolds really keep critters away from the veggies?) Since this is just one of my projects planned for this spring, so we'll see how far I get with it. |
