step 5

for our final layer, we used compost from one of our piles in the back yard.  since we were a little limited in what we could use, we made our layers a little thicker to compensate.  be sure to follow the pattern and to water.  make as many layers as you need, the height of the plants will determine the depth of the bed and if you are going to put in seeds, be sure to make it deep enough to accomodate the roots that will form.
