Germination & Seedling
2-3 weeksSeeds sprout within 7-10 days; cotyledons emerge followed by first true leaves. Plants grow rapidly establishing a compact bush form.
Keep soil consistently moist but not waterlogged. Protect from heavy rain and strong winds. Thin to proper spacing once seedlings have 2-3 true leaves.
Vegetative Growth
3-4 weeksPlant develops robust bushy foliage with multiple stems and branches. Leaves are trifoliate (three-leafed) and medium green. Plant reaches 12-18 inches in height.
Provide consistent moisture and monitor for pests. Mulch around plants to retain moisture and suppress weeds. No staking needed as these are bush beans.
Flowering
2-3 weeksSmall white, pink, or purple flowers appear in clusters along the stems. Flowers are typically self-fertile and appear in abundance.
Maintain consistent watering during this critical stage. Avoid high-nitrogen fertilizer which encourages foliage over flowers. Monitor for bean beetles and other pests.
Pod Development & Maturation
4-5 weeksPods develop rapidly after flowering, elongating to 4-6 inches. Pods transition from green to yellow to brown as they mature and dry. Seeds inside become hard and fully mature.
Continue regular watering until pods begin to dry. As plants mature, reduce watering to encourage pod drying. Watch for signs of maturity (pods brittle, seeds hard).
Harvest & Curing
Ongoing until all pods maturePods are fully dry and brown, with hardened beans inside that rattle when shaken. Plants may partially desiccate on the stem.
Harvest when pods are completely dry and beans cannot be dented with fingernail. Pull entire plants or pick individual pods. Cure indoors for 1-2 weeks before threshing and storage.

Harvest Tips
For dry beans, allow pods to mature fully on the plant until they turn brown and brittle, typically 85-95 days after planting. Harvest in dry weather to prevent mold. Pull entire plants when most pods are dry, or pick individual mature pods. Spread harvested plants on a tarp to cure for 1-2 weeks in a warm, dry location. Thresh beans by shelling by hand or threshing mechanically, then winnow to remove chaff. Store in airtight containers in cool, dry conditions (50-70°F, 40-60% humidity) for several years.
Fun Facts
