Well July is pretty late to start a big garden, but you still have time to grow a fall crop if you get your vegetables in now. Green beans, lettuce, Swiss chard, radishes, spinach, broccoli can all be planted now for harvests before frost. It's too late to plant potatoes, onion and tomatoes. Just be sure to keep your seedlings moist if the weather gets really hot. The key is to time it so they mature during the cooler weather in fall. So, get planting now.
