Hello all,

I removed a couple of very overgrown bushes in my back yard and found a walled area that I hope will work as a raised vegetable plot. It is fully equipped with irrigation, but could do with the addition of some soil to raise the level to the height of the wall. I have started some composting, but I am wondering what else I should be doing? The current soil is general Phoenix back-yard dirt and I have about 6 inches to fill - what would you suggest to best enrich the bed? The plan is for a variety of veggies.
