Cinder Block Garden

Ljkellar added on August 12, 2016 | Answered

I created a rather large raised garden with cinder blocks and loved it! Great results for first three years. Then this year nothing grew tall and nothing produced. It was green but that's it. Tested soil and was told pH is too high. They blamed the blocks for leaching lime. Suggested I tear down blocks and replace with wood. Is there another option? Can I lower pH? Should I line it and with something? I'm so lost without the garden and totally frustrated. Appreciate any suggestions. Thanks
