Cinder Block Herb Garden Border Ideas

This year we decided to put a border around our flower garden using concrete cinder blocks left over from previous projects we have been working on around the house.  Not only did we decide to reclaim concrete blocks but we  had the idea to plant an herb and flower garden in each of the spaces of the concrete blocks.  We are always working on fun garden projects and looking for ways to use things we already have on hand, so this was a perfect fit for us.  Here is how we did it.

Concrete (Cinder) Block Herb Garden Border

Put concrete blocks end to end around the area you need border.  For us, we did it around our flower garden filled with mulch.

Using Moisture Control Potting Mix and compost add roughly 2 Tlbs. of sulfur powder per gallon of soil.  The sulfur powder helps neutralize the lime that excretes out of concrete that often results in chlorosis. Fill your blocks ¼ of the way with soil then insert your herbs or flowers and cover with remaining soil packing lightly.

This is a great way to have a functional garden border and if you are so inclined feel free to decorate your blocks prior to using.  You can use paint, mosaic, or other fun materials to give your border your personalized touch.

We are currently using the LiquaFeed All Purpose Plant Food Advance Starter Kit to keep our vegetable garden flourishing.  It really is making a difference, but for the concrete block herb garden we are using Shake n’ Feed Moisture Control All Purpose Plant Food since it’s more of a container garden for the herbs.

    What a neat idea, thanks for sharing

  6. What a good Ideal!!!

  7. We’ve experienced that before but not on purpose. Some tomatoes just grew in between the hollow blocks we stocked up while building our house 😀

  8. Great idea! Cinder blocks are so cheap, and they work great for many things. I saw someone mix up a small bag of concrete and fill the holes smooth. You could hardly tell they were cinder blocks! Add a little paint and you’re in business.
