@talentryto- I agree with you about planting tomatoes as seedlings in most cases, but if you do it the right way and have the space, you can plant them using a direct seeding method.
I help my father plant his vegetable garden each year, and he direct-seed plants tomatoes in a row. He first prepares the ground by tilling it and laying down gardening ground plastic. When tomatoes form on the plants, this prevents them from coming into direct contact with the ground. Finally, he spreads tomato seeds throughout the row and covers them loosely with tilled soil.
This method for planting tomatoes probably isn't worth it for people who don't use a lot of tomatoes during growing season. But for people who either make a lot of sauces and soups with tomatoes, or preserve them, this is an ideal planting method for growing a lot of tomatoes in a vegetable garden.
