If you are concerned about underground pests constantly messing with your garden, the solution is rather simple: a raised garden bed with cinder blocks. This DIY project can be easily made, especially if you have some blocks used in some other project before and salvaged; the result is the same if you use new cinder blocks. The tutorial is from a project involving an 18 feet long by 4.5 feet wide garden. Once you’ve marked the area, you can begin digging a few inches in the ground and afterward make the ground as level as you can. Next follows laying the blocks, which is very hard to make in a level way.
But it must be done, so take your time and work with one at a time. The process is slow and the layer should have a number of 32 blocks. You also have to take it back up a few blocks at a time to lay the hardware cloth. Before placing the second layer – a much faster process than the previous – fill the cinder blocks with dirt. The same thing should be done to the second layer as well. Your raised garden bed is complete!
