I will order those melons today.
I think if have my garden set up in my mind. I will make 4, 16 inch x 8 foot raised beds. I will have a 16 inch walkway between two beds to give me room to navigate between the them.
I will need 168, 8 x 8 16 inch cinder blocks to make the beds 24 inches high and on top of that I will add 24 2 inch caps (to sit on)
making the total height 26 inches. On the blocks making up the sides I will plant herbs and flowers in the holes.
