I've always thought building my beds each year is about the same as cooking gumbo. For gumbo, you make a roux of flour and oil (dirt), then you look in the refrigerator and find the leftovers from previous meals and add them with some water. For the garden bed, add all the organics you can locate with some water. With Gumbo, you can spice it up a little with some hot sauce. For the garden bed, add something like compost for the extra spice. Gumbo is great as are good garden beds.
