How to grow green beans for a great salad

One of the easiest and most rewarding vegetable crops for northern gardeners are green beans. Whether you call them snap, string, shell or dried, green beans grow relatively quickly, require only a bit of care and produce bountiful crops for fresh eating or preserving.

Pole vs. Bush Beans

Green beans come in two basic growing styles: bush or pole. Bush beans grow about a foot high in bushy plants that tend to produce their crops all at once. They are prolific and are popular with gardeners who like to can or freeze their beans. Popular bush bean varieties include Blue LakeFrench Filet or wax beans. Pole beans are climbers, which means you typically can get more beans per square foot of garden. Climbing French is one of my favorite climbing beans. However, you do need to provide a support, which may be as simple as some bamboo poles lashed together or a length of wire fencing. Pole beans also tend to produce over a longer period of time, so if you are growing beans mostly for fresh eating, pole beans are a good option.

Planting, Growing, Harvesting

Mixed with cucumbers and other summer vegetables, green beans make a great salad.

Beans should be planted in the sunniest part of the vegetable garden. The primary key to success with green beans is to not plant too early. Beans want the soil to be warm, and if it is damp or cold, the seeds will just rot in the ground. Place the seeds about 3 inches apart and 1 inch deep for bush beans. Pole beans can be planted about an inch deep around the support system. Beans do not require a lot of fertilizer, but if you know your soil is depleted, you could add some compost or a formula specifically for vegetables. Water the seeds well and maintain consistent moisture while the beans germinate. Beans need about an inch of moisture a week.

The seed packet will tell you how long to wait before harvest, but many beans will be producing a crop within 50 or 60 days. Once the beans start coming, be sure to harvest regularly. Picking the beans indicates to the plant that it still needs to set seed to reproduce, so it will continue to produce beans. If you want to harvest some dried beans or seeds from your plants, let the last batch of beans remain on the vines until the pods are dried and yellowed. The seeds inside can be saved until next year. Some beans are intended for drying (or can be eaten either fresh or dried). Those beans, such as Cherokee Trail of Tears,Rattlesnake and Cannellini, can be left on the plants until they are dry, then remove the dried beans for your next batch of chili or baked beans.

Pests and Diseases

The biggest pest I have found with beans are rabbits, who have a nasty habit of munching the top off of seedlings as they emerge from the soil. Fencing or other cover is about the only way to keep them off the beans. Cutworms or bean leaf beetles can also be a problem. Beans can also be bothered by fungal diseases, but these can be reduced by not crowding the vegetable garden so there is adequate air circulation.

It is the mission of MSHS to serve Northern gardeners through education, encouragement, and community. Through a variety of educational programs, classes and conferences, and by publishing an award-winning magazine, Northern Gardener, MSHS helps its members and the general public to be better gardeners in USDA plant hardy Zones 3, 4 and 5. MSHS’ plant donation network, Minnesota Green, started in 1988, serves the greening efforts of volunteer gardeners throughout the state. Minnesota Green promotes grassroots efforts to revitalize communities by coordinating the donation and distribution of nurseries and greenhouse’s flowers and trees to be planted in public spaces statewide. MSHS was formed in 1866, as an association of fruit growers who took on the challenge of growing apples and other fruits in a northern climate. Two years later, the association became the Minnesota State Horticultural Society to recognize the importance of all phases of horticulture development in rural and urban Minnesota. In 1873, the Minnesota Legislature approved an act providing for the publication and distribution of 2000 copies of all the transactions of the society. 1894 marked the birth of one of the longest continually published horticultural magazines in the country: Northern Gardener, formerly known as Minnesota Horticulturist.
