I have an over-abundance of landscaping bricks (the kind that are rectangular on one end and bullet-nosed on the other), and a shortage of planters for my new container garden. I've been using free buckets from bakeries and fast food places, but the supply is running low at the moment.

So, can I build raised beds on my concrete patio using the landscaping bricks? Are there any drawbacks to using this method?

Thanks for your input.
