Understanding Navy Beans

What are Navy Beans?

Navy beans, also known as pea beans or haricot beans, are small white beans that are a staple in many cuisines. They have a mild flavor and a creamy texture when cooked, making them ideal for various dishes like soups, stews, and salads.

Nutritional Benefits of Navy Beans

Navy beans are highly nutritious and provide essential vitamins, minerals, and dietary fiber. They are a good source of protein, complex carbohydrates, and folate. Navy beans are also low in fat and contain no cholesterol.

Selecting the Right Navy Bean Varieties

When choosing navy bean varieties, consider your climate and growing conditions. Some popular varieties include Great Northern, Bountiful, and Tender crop. Consult with local nurseries or agricultural extension services for recommendations specific to your region.

Preparing for Navy Bean Cultivation

Choosing the Planting Site

Navy beans thrive in full sunlight, so select a location that receives at least six hours of direct sunlight daily. Ensure the site has well-draining soil to prevent waterlogging and root rot.

Soil Preparation

Prepare the soil by removing any weeds, rocks, or debris. Navy beans prefer loamy soil with a pH level between 6 and 7. Amend the soil with organic matter, such as compost or well-rotted manure, to improve its fertility and drainage.

Seed Selection and Treatment

Obtain high-quality navy bean seeds from reputable sources. Before planting, you can enhance germination rates by soaking the seeds in water for 24 hours. This process softens the seed coat and promotes faster and more uniform germination.

Planting Navy Beans

Determining the Optimal Time for Planting

Navy beans are warm-season crops and require soil temperatures above 60°F (15°C) for successful germination. Plant them after the last frost date in your area when the soil has warmed up.

Direct Sowing vs. Transplanting

Navy beans are typically directly sown into the garden, but you can also start them indoors in biodegradable pots if you have a short growing season. Transplanting should be done carefully to avoid damaging the delicate roots.

Planting Techniques

Create furrows or holes in the soil, spaced about 2-3 inches apart. Plant the seeds 1-2 inches deep, with the eyes facing downward. Space the rows approximately 18-24 inches apart to allow air circulation and ease of maintenance.

Spacing Considerations:

Provide adequate spacing between navy bean plants to allow for air circulation and prevent the spread of diseases. If planting in rows, maintain a spacing of 2-4 inches between plants within the row and 18-24 inches between rows.

Succession Planting:

To extend your harvest and ensure a continuous supply of fresh navy beans, consider practicing succession planting. Sow new seeds every 2-3 weeks throughout the growing season, allowing for a staggered harvest and a prolonged bean harvest period.

Caring for Navy Bean Plants

Watering Requirements

Navy beans require consistent moisture, especially during flowering and pod development. Water the plants deeply but avoid overwatering, as excess moisture can lead to root diseases. Water in the morning to allow foliage to dry before evening.

Fertilizing Navy Bean Plants

Navy beans are moderate feeders and benefit from a balanced fertilizer. Apply a low-nitrogen fertilizer before planting and side-dress with compost or aged manure once the plants start flowering. Avoid excessive nitrogen, as it can promote lush foliage growth at the expense of bean production.

Controlling Weeds and Pests

Regularly weed around navy bean plants to reduce competition for nutrients and moisture. Apply a layer of mulch to suppress weed growth. Monitor for common pests like aphids, bean beetles, and spider mites. Consider organic pest control methods to minimize chemical use.

Providing Support for Climbing Varieties

If you’re growing climbing navy bean varieties, install trellises, stakes, or a bean tower to provide support for the plants as they grow. Proper support ensures better airflow, reduces disease risks, and makes harvesting easier.

Disease Management:

To prevent common diseases like powdery mildew or bacterial blight, practice good sanitation by removing and disposing of infected plant debris. Use disease-resistant varieties when available, and consider applying organic fungicides or biocontrol agents if necessary.


Navy beans are self-pollinating plants, meaning they have both male and female reproductive structures in each flower. However, wind or insect pollination can still enhance bean set and yield. Encourage pollinators, such as bees, by planting pollinator-friendly flowers nearby.

Trellising Options:

While navy beans generally do not require support, trellising or staking can help keep the plants upright and improve airflow. Consider using bamboo stakes, wire cages, or string trellises to provide support as the plants grow taller.

Harvesting and Storing Navy Beans

Recognizing Harvest Readiness

Navy beans are typically ready for harvest 90 to 120 days after planting, depending on the variety. Look for dry, brittle pods with fully developed beans inside. Open a few pods and ensure the beans are hard and glossy.

Harvesting Techniques

Harvest navy beans by gently pulling the entire plant or by handpicking the dry pods. Avoid shaking the plants vigorously to prevent premature seed dispersal. Collect the pods in a basket or container.

Drying and Storing Navy Beans

Dry the harvested navy bean pods in a well-ventilated area away from direct sunlight until the pods are brittle and the beans rattle inside. Shell the beans and store them in airtight containers in a cool, dry place. Properly stored navy beans can last for up to a year.

Seed Saving:

If you want to save seeds from your navy bean plants for future planting, allow a few pods to fully mature and dry on the plants. Harvest the dried pods, remove the beans, and store them in a cool, dry place in a labeled container. Ensure the seeds are fully dry before storing to prevent mold or mildew.

Cooking and Culinary Uses:

Once harvested and dried, navy beans can be stored long-term and used in a variety of delicious recipes. Soak the dried beans overnight before cooking to reduce cooking time. Navy beans are popular in soups, stews, salads, and side dishes. They are also a staple ingredient in dishes like baked beans and chili.

Crop Rotation:

To prevent the buildup of pests and diseases in the soil, practice crop rotation by avoiding planting navy beans or other legumes in the same location for consecutive seasons. Rotate with unrelated crops like tomatoes, corn, or lettuce to break pest and disease cycles.

Troubleshooting Common Navy Bean Growing Issues

Disease Prevention and Management

Common diseases that affect navy beans include powdery mildew, bacterial blight, and common bean mosaic virus. Implement preventive measures such as crop rotation, providing adequate spacing, and using disease-resistant varieties. Treat infected plants promptly with appropriate organic fungicides or bactericides.

Dealing with Pest Infestations

Pests like aphids, bean beetles, and spider mites can damage navy bean plants. Encourage beneficial insects like ladybugs and lacewings, and use organic insecticidal soaps or neem oil to control pest populations. Regularly inspect your plants for signs of infestation.

Nutrient Deficiencies and Imbalances

Monitor the appearance of your navy bean plants for signs of nutrient deficiencies, such as yellowing leaves or stunted growth. Conduct a soil test to identify any imbalances and adjust your fertilizer application accordingly. Supplement with organic fertilizers or soil amendments as needed.
