How to Grow Bush Blue Lake Bean
Bush Blue Lake Bean
Phaseolus vulgaris
vegetableBush Blue Lake Bean is a compact, bushy variety of common bean that produces long, slender green pods perfect for fresh eating and canning. This determinate cultivar grows 12-16 inches tall without requiring support stakes, making it ideal for small gardens and container growing. The beans mature relatively quickly and produce prolifically over a concentrated season.

Germination
7-10 daysSeed sprouting and emergence of cotyledons above soil; tiny white root system developing below.
Keep soil consistently moist but not waterlogged. Soil temperature should be 60°F or warmer for best germination. Thin seedlings if densely seeded.
Seedling & Early Vegetative
2-3 weeksEstablishment of true leaves (oval-shaped leaflets); plant grows 2-4 inches tall with compact bushy form.
Maintain even moisture. Once seedlings have 2-3 true leaves, thin to 4 inches apart. Avoid high-nitrogen fertilizers which promote leaf growth over pods. Provide support if wind is strong.
Flowering
1-2 weeksSmall white, pink, or purple flowers appear at leaf axils; plant reaches mature height of 12-16 inches.
Ensure consistent watering during this critical stage; inconsistent moisture causes flower and pod drop. Apply balanced fertilizer. Monitor for pests and diseases. Avoid overhead irrigation.
Pod Development & Maturation
2-3 weeksFlowers fade and pods elongate to 5-6 inches; pods transition from pale green to deep green when fully mature for fresh eating.
Continue consistent watering. Mulch around base to retain moisture and regulate soil temperature. Pick pods regularly to encourage continued production. Watch for common pests like spider mites and Mexican bean beetles.
Harvest & Production End
1-3 weeks (or longer with cool weather)Pods reach full size and color depth; plant production slows as temperatures rise (in summer) or decline (in fall).
Harvest pods every 2-3 days for tender snap beans. For dry shell beans, leave pods on plant until brown and dry. Allow some pods to mature fully for seed saving if desired.

Common Pests
-
Hand-pick yellow egg clusters and larvae daily; use row covers for young plants; apply spinosad or neem oil; encourage native predators
-
Increase humidity and watering frequency; spray with water to dislodge; use neem oil or sulfur dust; avoid excessive nitrogen fertilizer
-
Use row covers on young plants; hand-pick beetles; apply insecticidal soap; remove crop debris promptly in fall
-
Ensure good air circulation; water at soil level only; apply sulfur dust or potassium bicarbonate; remove infected leaves
-
Avoid overhead watering; remove infected leaves; apply sulfur fungicide; choose resistant varieties; practice crop rotation
Uses
Fresh Snap Beans
CulinaryBush Blue Lake beans are prized for fresh eating with their tender, crisp pods and mild flavor. They are excellent steamed, sautéed, roasted, or eaten raw in salads. [source]
Canning & Preservation
CulinaryThe uniform pod size and high yield make this variety ideal for home canning. Properly preserved Blue Lake beans retain their texture and flavor for months. [source]
Dried Shell Beans
CulinaryIf pods are allowed to mature fully, the dried beans inside can be shelled and stored for winter cooking, providing a protein-rich staple. [source]
Pollinator & Beneficial Insect Support
WildlifeBean flowers attract bees and other pollinators, supporting the broader garden ecosystem while beans are nitrogen-fixing legumes that improve soil fertility. [source]
Soil Amendment & Crop Rotation
HouseholdAfter harvest, the plant material can be worked into the soil as green manure, enriching it with nitrogen for subsequent crops. [source]
Harvest Tips
Pick pods when 5-6 inches long and pods snap crisply when bent (snap bean stage), typically 50-60 days after planting. Harvest every 2-3 days to maintain tenderness and encourage continuous flowering. Wear gloves or handle carefully to avoid damaging the delicate vines. For dried beans, allow pods to brown on the plant, then harvest, dry completely indoors, and shell. Morning harvests when pods are still turgid yield crispest beans.
Fun Facts
- 🌱 Bush Blue Lake beans are a deterministic variety, meaning they set flowers and pods all at once within a concentrated period, unlike indeterminate pole beans that produce continuously throughout the season.
- 🌱 The 'Blue Lake' name references the original variety developed near Blue Lake, Oregon in the 1900s, which became so popular for canning that it is now the gold standard bean for commercial freezing and canning operations.
- 🌱 Beans are nitrogen-fixing crops that form symbiotic relationships with Rhizobium bacteria in the soil; planting beans improves soil fertility naturally, making them excellent for crop rotation and sustainable gardening practices.
