5. Green beans
Other than watering regularly, green beans or snap beans require very little maintenance. They germinate easily from seed and are also resilient to many diseases. Although both bush and pole beans are easy to grow, if you are growing beans in containers, bush beans are ideal (as they do not require as much support).
Growing best in full sun, you should not start these seeds indoors — as they may not survive transplanting. After the last frost (when the soil temperature is a minimum of 48 degrees Fahrenheit), plant seeds one-inch deep and two inches apart. Learn more here.
