Last year as a first time gardener I successfully grew tomatoes on my deck in Miracle Grow in large pots. This year I've built a large cedar planter for the deck and will move the pots to the driveway. I have to decide soon what type of soil to use. For the new planter I'm torn between Mel's Mix and Miracle Grow. Also what to do about the soil in the pots? Can I reuse it? Add compost to it? If so, in what ratio? Please forgive all the questions, but I am really confused.
