My Garden Would Not Grow

I have been trying for a couple years now to grow a successful garden. At first the task seemed daunting so I broke up my gardening aspirations into sections and decided to tackle one task at a time. It was late last year when I found that a certain part of my garden was not producing as well as I had hoped. I called a friend of mine, who also gardens, and explained my dilemma. She recommended Soil remediation. Basically, I needed someone to come in and dig out the ill soil and replace it with a more purified soil. I was promised that if I were to try this, my garden would grow as I had hoped.
