      • Determine how large the garden needs to be
    • Begin by
      • Selecting your 10 vegetables
        • 5 warm season
        • 5 cool season
      • Research each and make a chart

      • Heavy nitrogen feeders
      • Avoid pesticides
      • Cool Season Plants
    • Nightshade
      • A family of toxic plants that includes: tomatoes, peppers, potatoes & eggplants
