If you succession plant, sowing seeds every week in a few different planters, you'll create a supply of greens that will be ready in a steady stream all summer. Greens like these are also good for sheltered decks or patios that don't get much sun, since lettuce doesn't like a lot of heat and will grow better during the summer in cool shade
