Germination & Seedling
7-14 daysSeeds sprout in 7-10 days with warm soil. First true leaves emerge and seedlings develop their characteristic bean leaf shape.
Ensure soil temperature is 60°F minimum; ideally 70°F+. Keep soil consistently moist but not waterlogged. Protect from cutworms with collars if needed.
Vegetative Growth
3-4 weeksPlants develop bushy foliage with 3-5 true leaves per stem. Growth is vigorous and compact, typically reaching 12-18 inches in height.
Thin seedlings to 4-inch spacing if direct seeded. Provide consistent moisture and avoid nitrogen-heavy fertilizer to prevent excessive leaf growth. Mulch around plants to retain moisture.
Flowering
2-3 weeksSmall white or pale yellow flowers appear in clusters along the stems. Plants are in peak growth with full canopy development.
Continue consistent watering; do not allow soil to dry during flowering. Watch for pests. Avoid high-nitrogen fertilizers which can reduce flower and pod set.
Pod Development & Shell Bean Stage
2-3 weeksPods enlarge rapidly, displaying the characteristic speckled coloring with red streaks on green background. Beans inside are visible and fully formed.
Harvest pods when fully mature but still slightly tender (around 60-70 days) for eating as shell beans. Pods should be plump and beans well-developed inside.
Dry Bean Stage
2-3 weeksPods mature fully, turning brown and papery. Beans inside rattle when shaken. Plants naturally yellow and leaf drop begins.
Allow plants to dry in the field if weather permits. Leave pods on plant until completely dry (75-90 days total). Harvest before heavy rain damages pods.

Harvest Tips
For shell beans: harvest when pods are mature, filled, and just beginning to yellow (60-70 days). Shell the beans and use fresh or cook immediately. For dried beans: leave pods on plant until completely brown and papery (75-90 days). Harvest entire plants, hang upside down to dry further, then shell. Store dried beans in cool, dry location in airtight containers for up to 2 years.
