1. Select the varieties you want to grow in every season and buy organic seeds.
2. Prepare garden area by tilling or breaking up soil, and spreading and mixing in 1 or 2 inches of compost (use organic compost made from food trimmings, chopped leaves, grass clippings, etc.). In the week before you plan to plant, go over your garden soil with a rake or trowel to break up any remaining soil clumps and eliminate weed seedlings. Do this twice in the days leading up to planting and immediately before planting seeds.
3. Direct-seed greens into prepared garden soil. Many growers like to plant two sections or rows about every two weeks throughout the growing season to get a staggered and continuous harvest.
