Seedling
7-10 daysYoung plants emerge with cotyledons and first true leaves. Stems are tender and green.
Keep soil consistently moist but not waterlogged. Provide full sun. Thin seedlings to proper spacing if direct seeded. Protect from cold snaps.
Vegetative Growth
3-4 weeksBush habit develops with multiple branching stems. Leaves are trifoliate and dark green. Plant is compact and bushy.
Maintain consistent moisture. Avoid high-nitrogen fertilizers that promote foliage over flowers. Monitor for pests. Mulch to conserve moisture and regulate soil temperature.
Flowering
2-3 weeksSmall white, purple, or pink flowers appear in clusters at leaf axils. Flowers are delicate and short-lived.
Ensure adequate water during this critical stage. Avoid disturbing plants. Do not apply high-nitrogen fertilizer. Flowers attract pollinators; support bee activity.
Pod Development
3-4 weeksGreen pods form and elongate, typically 3-4 inches long. Pods contain developing beans inside.
Maintain consistent soil moisture for pod fill. Support with mulch to prevent pod rot. Watch for common bean beetles and spider mites. Begin light harvesting for snap beans if desired.
Maturation & Drying
2-3 weeksPods turn yellow, then brown and papery. Seeds inside mature to glossy black. Plant foliage may begin to senesce.
Reduce watering to allow pods to dry. Leave pods on plant until fully mature and dry (brittle pods). Harvest before fall frost or heavy rain. Allow pods to cure further indoors if needed.

Increase humidity with regular watering or misting. Use strong water spray to dislodge mites. Apply neem oil or sulfur sprays. Introduce natural predators like ladybugs.
-
Use row covers during early growth. Hand-pick beetles. Apply insecticidal soap or neem oil. Practice crop rotation to reduce overwintering populations.
-
Ensure good air circulation; space plants properly. Avoid overhead watering. Apply sulfur dust or neem oil at first signs. Remove infected leaves.
-
Use resistant varieties when available. Remove infected leaves promptly. Avoid overhead irrigation. Ensure adequate spacing for air flow. Destroy plant debris after harvest.

Harvest Tips
For snap beans, harvest pods when green and tender, 2-3 inches long, before beans inside enlarge (typically 50-60 days). For dry beans, allow pods to mature fully on the plant until brown and papery (90-120 days). Pods should rattle when shaken. Harvest before first frost, then shell and dry beans indoors for 1-2 weeks before storage. Store dried beans in airtight containers in cool, dry location for up to 1 year.
