Good idea. However, I guess that you would have to do a really good job covering/ painting them. Otherwise, they would look very cheap. Another challenge I can foresee is moving them after been filled out with soil. I think they would break easily if they are not handled carefully.

Really cute idea. Thank you Roselee!

My mom did use styrofoam containers before, more so because she just wants any kind of container for all her plants, not so much that she thought there was some good reason to. After a few seasons, the styrofoam breaks apart, and yes, if you are relocating it, you do have to be careful of that, too.

Now, if it were protected with some kind of sealant, that might be a different story.
