Seedling
1-2 weeksCotyledons emerge within 7-10 days. First true leaves appear shortly after. Plants are small and delicate.
Keep soil consistently moist but not waterlogged. Protect from strong winds. Thin seedlings to proper spacing if direct seeded.
Flowering
2-3 weeksSmall white or light purple flowers appear in clusters along the stems. Plants reach full size.
Maintain moderate watering; flowers are sensitive to drought stress. Continue weeding. Do not over-fertilize. Flowers are self-fertile.
Pod Development
3-4 weeksGreen pods form and elongate. Pods contain developing beans inside. Foliage remains green.
Maintain even moisture to prevent pod drop. Reduce watering slightly as pods mature. Support with staking if needed, though bush varieties rarely require it.
Dry Bean Stage
2-3 weeksPods turn brown and papery. Beans inside harden and rattle in pods when shaken. Foliage yellows and dries.
Reduce watering significantly or stop entirely. Allow plants to fully dry in the field. Harvest when pods are completely brown and brittle.
Common Pests
-
Hand-pick adults and egg clusters. Use row covers early in season. Apply neem oil or spinosad if infestation is severe.
-
Spray with strong water stream. Use insecticidal soap or neem oil. Encourage beneficial insects like ladybugs.
-
Increase humidity. Spray with water or neem oil. Monitor undersides of leaves regularly.
-
Store dried beans in airtight containers in cool location. Freeze beans at 0°F for 1 week before storage.
-
Improve air circulation. Avoid overhead watering. Apply sulfur dust or fungicide if symptoms appear.
