Cinder Block Raised beds freeze and break?

Posted by NE-WVHills 5 (My Page) on

I am very near buying stuff to build cinder block raised beds and see a lot of comments here on using them, but I have one question that I have not had good luck finding an answer to... If you're in a climate with harsh winters (zone 5, bordering 4), if you fill the holes in the cinder blocks to plant things in, will the cinder blocks crack/break over winter from the freezing and thawing of the soil in the holes?

I'm in zone 5.

I have compost in the cinder blocks - and they have now been filled for one season thus far. No problem with breakage.

My blocks are only two blocks high though; mostly used it as a retaining wall but I still use it to plant in.

I'll probably only go one or two courses high as well. I got to wondering about this and asked a local cinder block supplier when price checking and he seemed to think they would break, so I figured I'd check with others doing this to see what's been seen in practice.
