My wife and I decided to plant a pretty big garden this year. We wanted to see how long certain items take and if they would grow here in Colorado. We planted early, the first week in May. It was probably a couple weeks early. We had to cover the plants a couple nights. Everything lived and is thriving. We wanted to see how long lettuce took. We cut our mixed greens 1 month after they went into the ground. We yielded about 4 pounds of lettuce. Our cost was 3 dollars and got 20 dollars in greens. If you staggered the planting times you could have mixed greens all summer. Some other items we planted: white cherry tomatoes, white patty pans, heirloom pineapple tomatoes, sweet corn, watermelons, cantaloupe, romaine, bok choy, leeks, scallions, jalapenos and a shit load of herbs.
