How to Grow Bush Bean Blue Lake
Bush Bean Blue Lake
Phaseolus vulgaris
vegetableBush Bean Blue Lake is a compact, determinate bean variety prized for its long, slender, tender green pods and excellent flavor. This dwarf cultivar grows 12-18 inches tall and produces abundantly without requiring a trellis, making it ideal for small gardens. The beans are stringless when picked young and are popular for fresh eating, freezing, and canning.

Growth Stages
Germination & Seedling
7-14 daysSoil-embedded seeds sprout with cotyledons (seed leaves) emerging within 7-10 days. First true leaves appear shortly after.
Keep soil warm (65-75°F) and consistently moist. Thin seedlings if direct-seeded to proper spacing. Ensure full sun exposure to prevent leggy growth.
Vegetative Growth
20-30 daysPlants develop bushy, compact foliage with multiple stems and true leaves. Plant reaches 12-18 inches tall and forms its structural framework.
Maintain consistent moisture and monitor for pests. Do not over-fertilize with nitrogen, as it encourages excess foliage over flowering. Support is not needed for bush varieties.
Flowering
10-14 daysSmall, white or pale purple flowers appear in clusters among the foliage. Flowers are self-fertile and begin setting pods.
Maintain consistent watering as flowers and early pods are forming. Avoid overhead watering to prevent flower drop. Continue monitoring for pests.
Pod Development & Maturation
15-20 daysGreen pods elongate rapidly (typically 5-7 inches long), becoming tender and bright green. Pods are ready for harvest when young and before seeds visibly bulge.
Water consistently and deeply; pod development is water-intensive. Harvest frequently to encourage continued production. Pick pods regularly to prevent overmature seeds.
Late Season & Decline
Varies with climateProductivity decreases as temperatures drop or heat stress occurs. Remaining pods become stringy and seeds harden inside.
In cooler climates, plant stops producing. In warm regions, provide shade cloth or extra water if temperatures exceed 85°F. Clean up plants and discard if disease is present.
Common Pests
-
Hand-pick yellow egg clusters and beetles from leaf undersides. Spray neem oil or spinosad for heavy infestations. Plant trap crops like sunflowers nearby.
-
Use row covers early in season. Spray insecticidal soap or neem oil. Remove and destroy infested plant material.
-
Spray with strong water stream to dislodge. Apply insecticidal soap or neem oil. Encourage beneficial insects like ladybugs.
-
Increase humidity by misting plants. Spray neem oil or sulfur. Remove heavily infested leaves.
-
Improve air circulation. Water at soil level only. Remove infected leaves. Apply sulfur dust or fungicide if severe. Choose resistant varieties when possible.
-
Ensure good air circulation. Avoid overhead watering. Apply sulfur or potassium bicarbonate fungicide. Remove heavily affected foliage.
Uses
Fresh steaming and side dishes
CulinaryYoung Blue Lake pods are tender and flavorful when steamed, sautéed, or blanched. Their stringless quality and mild flavor make them versatile for simple preparations or as a side dish. [source]
Freezing and canning
CulinaryBlue Lake beans are a standard choice for home food preservation. Their consistent size, tender texture, and good flavor retention make them excellent for freezing or pressure canning. [source]
Nutritional benefits
MedicinalBush beans are rich in fiber, plant-based protein, B vitamins, and minerals like manganese and folate. They support digestive health and provide sustained energy. [source]
Seed saving
HouseholdAllow a few mature pods to dry on the plant at season's end. Harvest dried pods, extract seeds, and store in cool, dry conditions for 3-5 years of viable seed. [source]
Nitrogen fixation and soil improvement
WildlifeLike all legumes, Bush Bean Blue Lake forms symbiotic relationships with nitrogen-fixing bacteria in nodules on roots, enriching soil with usable nitrogen for subsequent crops. [source]

Harvest Tips
Harvest pods when 5-7 inches long, firm, and bright green—typically 8-10 days after flowering begins. Pick every 2-3 days to encourage continuous production. Snap pods cleanly from the plant by holding the stem with one hand and pulling the pod with the other to avoid damaging the plant. Early-morning harvesting provides crispest, highest-quality pods. Stop harvesting if pods are mature or stringy; allow a few pods to fully mature if saving seeds for next season.
Fun Facts
- 🌱 Blue Lake is named for a lake in Oregon where the variety was developed in the 1960s as an improvement over earlier bean cultivars, combining bush growth habit with excellent pod quality.
- 🌱 Bush Bean Blue Lake plants produce their entire crop within a relatively narrow window of time (4-5 weeks), making them ideal for succession planting every 2-3 weeks for continuous harvest.
- 🌱 Unlike pole varieties, bush beans mature all at once and are preferred by commercial canners and home preservers because the uniform ripening allows for one-pass harvesting.
