Do you like the productivity of pole beans but don't have room for a large trellis? Consider planting half-runner beans. This type of green bean has a growth habit somewhere between that of a bush bean and a pole bean. 

What are Half-Runner Beans

Like pole beans, half-runner beans will continue to produce blossoms when young beans are removed from the vines. Typically, bush beans produce green beans for about a two week period and need to be successively planted in order to extend the harvest period. 

Like bush beans, half-runner beans have a much more compact growth habit. While they do produce runners, the vines only reach lengths of three to five feet (1-1.5 m.) depending upon the variety. Pole beans can send runners as far as 20 feet (6 m.) across the garden. Truly, half-runner beans present the best attributes of both bean types and are the perfect solution for some gardens.

Do Half-Runner Beans Need a Trellis?

While half-runner bean plants don't require trellising, they produce better and are certainly easier to pick when given something to climb. Due to their compact size, half-runner beans can be planted alongside a short garden fence or around a garden stake. Half-runners are ideally suited for companion planting among corn stalks or in the traditional three sister planting of corn, beans, and squash.

Some gardeners prefer planting half-runner beans in rows like bush beans. Space the rows wider apart than when planting bush beans, leaving a minimum of three feet (1 m.) between rows to allow room for harvesting.

How to Grow Half-Runner Beans

Sow half-runner beans in the spring after danger of frost has passed and the soil has warmed. Planting beans one inch (2.5 cm.) deep is recommended. When sowing in rows without support, sow seeds two to four inches (5-10 cm.) apart and thin to six inches (15 cm.) to allow for horizontal growth. Sowing a new row every two to three weeks can extend the harvest and provide beans throughout the growing season.

Gardeners can expect germination within two weeks. Soaking seeds prior to sowing can reduce germination times. When trellising, put supports in place prior to planting. Place the bean seeds close to the trellis. If you find you've planted the seeds too far from the support, simply direct the young seedlings toward the trellis. Hook a leaf onto the support or gently wrap the runner around the pole.

Water beans when planting and when the soil begins to dry. Green beans prefer a moist but not soggy growing medium. Mulch to control weeds and periodically use a low nitrogen fertilizer, particularly if the beans are slow to flower and produce. Popular heirloom varieties include Mountaineer White and State half-runner.
