What are Navy Beans and Their Benefits
Before diving into the farming process, let’s explore what exactly navy beans are and why cultivating them can be highly rewarding.
An Introduction to Navy Beans
Navy beans, also known as haricot beans, are small, oval-shaped white beans that originate from South America. Their name comes from their extensive use as a staple food in the 19th century British Royal Navy. Packed with protein, dietary fiber, iron, magnesium, and folate, navy beans make for a nutritious, plant-based addition to one’s diet.
Nutritional Value
Some key nutrients found in navy beans include:
- Protein: 9 grams per 1⁄2 cup cooked serving, providing 18% of the Daily Value. Their protein is plant-based, making navy beans suitable for vegetarians and vegans.
- Fiber: 9.6 grams per 1⁄2 cup cooked serving, providing over a third of the recommended daily intake. The fiber aids digestion and promotes feelings of fullness.
- Iron: 22% of the Daily Value. Iron carries oxygen throughout the body and supports a healthy immune system.
- Magnesium: 24% of the Daily Value. Magnesium plays over 300 roles in the human body, including muscle and nerve function.
- Folate: 32% of the Daily Value. Folate forms red blood cells and helps prevent neural tube defects during pregnancy.
Health Benefits
Incorporating navy beans can offer numerous health advantages:
- Heart Health: Navy beans contain soluble fiber, magnesium, potassium, and omega-3 fatty acids to support heart health by lowering blood pressure and cholesterol.
- Digestive Health: The fiber delays gastric emptying to prevent spikes in blood sugar. This steady digestion promotes gut health and relieves constipation.
- Weight Management: Navy beans provide a lasting feeling of fullness, allowing one to feel satisfied with smaller, calorie-controlled portions that can aid weight loss.
- Diabetes Management: With a low glycemic index of 38, navy beans help regulate blood sugar levels, which is beneficial for preventing and managing diabetes.
Culinary Uses
Navy beans hold up well to cooking, offering a creamy texture and mild flavor that takes on the tastes of accompanying ingredients nicely. Their versatility allows them to be used in diverse dishes:
- Soups and stews like senate bean soup, garlic bean soup, minestrone, chili, and vegetable stew
- Hearty baked bean dishes
- Salads like three bean salad, white bean salad, and bean sprout salad
- Dips and spreads like hummus, bean dip, and white bean bruschetta
- Rice and bean sides like red beans and rice
- Falafel patties and veggie burger mixes
- Pureed for sandwiches and tacos fillings
Getting Started with Navy Beans Farming
Growing navy beans requires some initial preparation before sowing seeds. Key steps when starting out include:
Choosing the Right Climate and Location
When selecting a site, consider these optimal climate conditions:
- Temperatures averaging 70-80°F
- At least 6-8 hours of direct sunlight daily
- Low humidity levels
- Protection from heavy winds
Ideally, pick a location with well-draining, slightly acidic loam or sandy loam soil and nearby access to water. Avoid frost pockets or areas prone to flooding.
If your climate is unsuitable, cultivating navy beans in a greenhouse allows you to control factors like sunlight, temperature, airflow, and irrigation more precisely.
Preparing the Soil
Preparing the soil properly enables seeds to establish a healthy root system:
- Test soil pH and nutrient levels
- Adjust pH to 5.5-6.5 using lime or sulfur
- Mix in aged compost or manure
- Break up compact sections and clear debris
- Level the surface and create planting rows
Moist, nutrient-rich soil with good aeration and drainage helps plants thrive.
Soil Amendments
Some common amendments to improve soil conditions include:
- Compost: Boosts nutrient content and moisture retention
- Manure: Provides a slow-release fertilizer as it breaks down
- Peat moss: Lightens heavy clay soils to improve drainage
- Gypsum: Add to salty soils to remove excess sodium
- Dolomitic lime: Raises pH in acidic soils but won’t overwhelm
Determining Optimal Planting Time
Spring is the best season for planting navy beans in most regions once overnight temperatures remain above 50°F with no risk of further frosts. The soil temperature should have warmed to at least 60°F to spur germination.
In hot climates, planting in fall allows plants to develop over winter before setting seed pods as temperatures rise in spring.
Aim to plant 75-90 days before the first expected fall frost so plants have adequate time to reach maturity.
Caring for Your Navy Bean Crop
Once planted, navy beans need consistent care for a healthy, bountiful harvest:
Key Planting Techniques
Use proper planting techniques to avoid overcrowding and uneven growth:
- Sow seeds 1-2 inches deep
- Space 2-3 inches apart in rows 18-24 inches apart
- Plant 4-6 seeds per foot of row
- Cover lightly with fine soil
Thin young plants to 4-6 inches between stems once seedlings establish. This reduces competition for sunlight and nutrients.
Providing Consistent Irrigation
Navy beans require 1-2 inches of water weekly for robust growth. Insufficient moisture causes wilting and lower yields.
- Install drip irrigation or soaker hoses to target the root zone
- Water early in the day to allow foliage to dry out
- Check soil moisture levels to determine watering needs
- Increase watering during flowering and pod formation
Tip: Apply mulch around plants to retain soil moisture and reduce watering frequency.
Fertilizing Effectively
Fertilize plants every 3-4 weeks during the growing season:11
- Choose a balanced 10-10-10 or 5-10-10 nitrogen-phosphorus-potassium fertilizer
- Follow package instructions carefully to avoid burn
- Mix granules thoroughly into the top few inches of soil
- Liquid feeds can also be used if applied directly to soil, not foliage
Common deficiency symptoms and associated remedies:
| Symptoms | Treatment |
|---|---|
| Stunted growth | Add nitrogen fertilizer |
| Discolored leaves | Apply magnesium & iron supplements |
| Weak stems | Increase phosphorus levels |
Caution: Over-fertilization causes excessive foliage growth rather than pod production.
Managing Pests and Diseases
Scout plants routinely to spot issues early before they spread:
Common Navy Bean Pests
| Pest | Damage | Control Methods |
|---|---|---|
| Bean leaf beetles | Feed on leaves leaving skeletal damage | Hand pick adults, use floating row covers |
| Thrips | Distorted growth and silver patches on leaves | Blast with water, introduce predatory insects |
| Spider mites | Speckled leaves with fine webbing | Spray insecticidal soap or neem oil |
Common Navy Bean Diseases
| Disease | Symptoms | Prevention |
|---|---|---|
| Anthracnose | Sunken brown lesions on stems & pods | Crop rotation, avoid overhead watering |
| Rust | Reddish powdery coating on leaves | Resistant varieties, chlorothalonil fungicide |
| Root rot | Stunted plants, reduced yields | Improve soil drainage, limit nitrogen feeds |
Nematode parasitic worms stunt root systems and cause wilting. Solarize soil before planting to destroy larvae.
Companion planting garlic, onions, or marigolds can help repel pests too.
Harvesting and Storing Your Crop
Knowing optimal timing and methods for harvesting ensures you collect quality beans:
Identifying Maturity
Check navy bean pods daily as they near full maturity around 85-100 days after planting.
Signs pods are ready for picking:
- Pods turn yellowish or brown
- Pods and beans inside feel dry to the touch
- Beans detach easily when pods are split
- Lower leaves start yellowing
Harvest beans promptly once the bulk have dried to prevent storm damage or pests consuming the valuable seeds.
Effective Harvesting Methods
Pulling: Grasp plants near the base and uproot entirely. Further dry uprooted plants out of direct sun.
Cutting: Use shears or a sharp knife to cut each plant off just above soil level.
Allow pulled or cut plants to finish drying for 1-2 weeks laid out in a single layer in a warm, shaded spot until pods are crispy and brittle.
Shell dried pods by hand over a container to separate beans. Discard any insect-damaged or discolored beans.
Curing Beans Post-Harvest
Curing navy beans after harvest enhances their storage capability and flavor profile.
Curing process:
- Spread shelled beans in a single layer on mesh racks or screens in a dark, dry area with good airflow
- Allow to sit undisturbed for 1-2 weeks
- Stir or turn beans periodically so they cure evenly
- Check moisture levels regularly. Beans should feel hard and brittle when fully cured.
Tip: Add a fan to keep air circulating and speed moisture removal if beans feel damp.
Proper curing slows bean respiration rates for longer shelf life and intensifies the creamy bean flavor through the conversion of starches into sugars.
Storing Your Harvested Crop
Follow these guidelines for storing cured navy beans correctly:
- Place loose dried beans in airtight glass jars or food-grade plastic buckets with tight lids
- Store containers in a cool, dark cupboard or pantry around 55°F
- Avoid exposure to heat, sunlight, or moisture
- Label jars with bean type and year harvested
- Check periodically for moisture accumulation or signs of pests
- Use oldest beans first to maximize freshness
Stored under the right conditions, navy beans will remain edible for up to five years before flavor and texture decline.
Maximizing Yield Sustainably
Implement these growing practices to increase productivity and uphold environmental stewardship:
Support Structures for Vertical Growth
Create vertical support structures for plants to grow upwards rather than sprawling across the ground. Options include:
- Wooden poles and trellising
- Wire cages
- Strings suspended from overhead supports
Benefits include:
- Increased sun exposure for more pod production
- Improved pest monitoring and disease prevention
- Reduced fungus risk with airflow around plants
- Easier harvest without uprooting
Ensure supporting poles are thrust securely into the ground and monitors are tied loosely to prevent constriction as stems expand.
Pruning and Thinning
Strategically removing some plant parts and underperforming plants enables the remaining plants to gain more nutrients and produce greater yields.
Prune
- Excessively long trailing stems
- Low-lying branches prone to disease
- Leaves/stems with pest damage or infections
Thin Out
- Overly crowded seedlings
- Slow growing or spindly plants
- Volunteers far from primary plants
Discard debris promptly to prevent spreading issues to healthy plants nearby. Sanitize shears between plants with diluted bleach.
Integrated Pest Management
Reduce reliance on pesticides through diverse ecological strategies like:
- Interplanting onion, garlic, and marigolds to repel pests
- Applying kaolin clay sprays to irritate insects
- Installing bird houses or insect hotels to attract predators
- Handpicking larger pests like beetles
- Using pheromone or yellow sticky traps
- Releasing ladybugs or green lacewings to eat aphids
This protects local pollinators and wildlife while balancing the ecosystem.
Organic Enrichment Methods
Build soil health through incorporating organic matter annually. Strategies include:
- Composting plant debris on-site
- Growing cover crops like buckwheat, rye, or clover then tilling them under
- Mulching around plants with leaves or straw
- Rotating crops to prevent nutrient depletion
- Allowing some plants to go to seed to provide food for future beneficial insects
- Avoiding synthetic chemicals that eliminate microbial life
Vibrant living soil teeming with micronutrients and beneficial microbes supports stronger, more disease-resistant plants. Following sustainable growing practices maximizes navy bean productivity while protecting soil and water quality for future seasons.
Frequently Asked Questions About Navy Beans Farming
Can you grow navy beans from dried store-bought beans?
Yes! Select large, unbroken beans showing no signs of damage from purchased dried bags to plant in your garden. Optimal germination rates come from fresher beans less than a year old.
What are some signs my beans are ready to pick?
Mature picking indicators include browned or yellowing pods, crisp dry pods that split to reveal plump beans inside, detachment of internal beans when squeezed, and lower leaf yellowing.
Is it better to pull or cut plants when harvesting navy beans?
You can employ either uprooting or cutting methods effectively. Pulling entire plants allows hanging upside down for concentrated drying. With cutting, lay the removed plant sections out in a single layer. Both work well as long as ample additional drying time is provided before shelling beans from the pods.
How do I improve my yields for next season?
Key yield-boosting tactics include using vertical growing supports for increased pod concentration, pruning and thinning to reallocate resources to productive plants, amending soil with quality compost, practicing pest management, trialing container growing, and comparing productive varieties to choose optimal types for replanting.
What is the best way to control weeds organically?
Recommended organic weed control techniques include mulching heavily around plants to block light essential for weed growth, hand pulling young sprouts, practicing cultivation by gently stirring surface soil to uproot tiny weeds, and using corn gluten meal or vinegar applications to deter growth and seed germination.
