Concrete Block Raised Bed Gardens

I've recently become fascinated with concrete as a building material.  The cost is reasonable, a 8 inch x 8 inch x 16 block is around $1.20 each.  Enough about me, let's look at some examples.

The usual things will apply when creating a concrete block garden.

• Use a weed blocker on the bottom
• Minimum amount of soil should be 6 inches deep

It looks like this raised bed was made with 16 concrete blocks.  This makes this bed under $20 to make.  Please note that no mortar was used in-between the blocks.

• There are 2 rows of blocks
• The concrete blocks are staggered so seams don't line up
• A cap was used around the top to cover the holes in the concrete blocks
• The blocks are mortared in
