When shopping for vegetable plants, look for healthy green leaves that are turgid and without marks or spots. Lackluster plants have experienced some stress, making for a slow start in their development. Many smaller pots of veggies you'll see in the garden center will have several small plants clumped together. When you plant these as one large group in a pot, they'll compete for food, light, and air, and only the strongest will survive.
