I bet most of you do not know that the United Nations General Assembly has declared this year as the International Year of Pulses. What are pulses? Pulses are grain legumes and include dry beans, dry peas, chickpeas, and lentils.

Legumes are important crops around the world because they are part of a nutritious human diet, providing protein, fiber, minerals, and vitamins. Also, 25% of the pulses grown in the world are used for feeding livestock. The UN is recognizing pulses in 2016 not only for the nutrition they provide humans and livestock, but also because they are very sustainable crops. It only takes 43 gallons of water to grow one pound of pulses and they fix nitrogen, enriching the soils in which they are grown.

One way to observe the Year of the Pulses is to add more dry beans, chickpeas and lentils to your diet. It is certainly a healthy way to celebrate considering that dry beans can help lower cholesterol and aid in the prevention of diabetes and heart disease when they are regular part of your diet.

Another way take part in this special year of recognition is by growing some dry beans in your garden. Dry beans are an easy crop to grow. The most difficult part may be deciding what varieties to plant. There are hundreds available with a rich diversity of different types including the better known black, kidney, pink, red kidney, small white navy, and pinto beans to the lesser known cranberry, soldier, yellow eye, Jacob’s cattle markings, purplish, flageolet, and more.

Check out seed catalogs from companies that offer a wide selection of dry bean seed, including heirloom varieties that are a continuing trend in food gardening. It is a treat just to see the pretty pictures of the dry beans. One catalog you should peruse comes from the Vermont Bean Seed Company at As their name implies, they specialize in beans and in their catalog they offer information on what type of cooking is best for each type of bean. Baker Creek Heirloom Seeds ( and Seed Savers Exchange ( also offer a selection of dry bean varieties.

If you are wondering how difficult it is do grow dry beans, do not worry. If you can grow green beans, you can grow dry beans. Like green beans, there are bush type dry beans that stay more compact and pole types that will need some kind of support such as poles or a trellis. Also like green beans, they are a warm season crop. Wait to plant dry beans until after the danger of frost is past, the soil has warmed to at least 60 degrees F, and the average air temperature is above 50 F degrees.

One big difference in growing dry beans is the need to innoculate the seed with a soil bacterium that works with the bean plants’ roots to capture nitrogen from the air and “fix” it so it can be used for plant growth. Because you can not tell if your soil already has this natural bacterium present, experts recommend mixing your dry bean seed with Rhizobium leguminosarum, the specific innoculate needed for beans. You can obtain this innoculate from Vermont Bean Seed Company, other seed companies, or your local farm store or specialty nursery. Just make sure it contains the specific innoculate needed for beans.

Sidebar: Our own state already does its part in celebrating pulses by growing 115,000 acres of pulse crops, ranking seventh in the nation in pulse production. Plus, 43% of the lentils grown in the US are grown in Washington, making our state number one in US lentil production!
