Growing Navy Beans
- Choose an area that is well drained and that was not used for growing navy beans during the previous growing season. A garden plot that receives full sunlight is best suited for navy beans. The soil should not contain much clay and should have a pH of 6.0 to 7.0. You can buy a kit to test your soil's pH at a garden store or hardware store. If the pH is too low, you can add approximately 8 ounces of lime per square yard to raise the level by one point. In order to lower the pH by one point, add 3.6 ounces of rock sulfur or add composting materials such as leaves, sawdust, peat moss and wood chips.
- Wait until there is no danger of frost and the soil has reached at least 60 degrees F before planting. Plant the seeds approximately 1 inch deep and 3 inches apart. Plant in narrow rows to help combat future weed growth. Water immediately and evenly saturate the soil. Continue to water regularly on a daily basis.
- Most beans don't need to be fertilized, as they emit nitrogen into the soil. Weed as needed. Maintain good drainage and air circulation in order to prevent various plant diseases. Fungicides can be used to treat existing disease problems. Read the label of the fungicide before using to make sure it is safe for navy beans. Watch for cutworms and leaf beetles, as well as whiteflies, which can infect the beans with a virus. If necessary, choose an insecticide from your local home and garden store; many are available, but check the label for safety in regard to navy beans.
- Navy beans usually mature between 90 and 150 days after planting. When the bean pods are filled out firmly and are completely dry, they are ready to be harvested. Shell the beans and store them in a dry, airtight container.
