Seedling
1-2 weeksCotyledons emerge with true leaves following. Seedlings are tender with visible compound leaflets.
Protect from direct wind. Keep soil consistently moist but not waterlogged. Thin to proper spacing once established.
Vegetative
3-4 weeksBushy plant develops multiple stems with compound trifoliate leaves. Plant reaches 12-18 inches tall.
Ensure consistent moisture and good drainage. Mulch around plants to retain moisture and suppress weeds. Avoid high-nitrogen fertilizer.
Flowering
2-3 weeksSmall white or pale pink flowers appear in clusters at leaf axils. Flowers are delicate and attract pollinators.
Maintain regular watering during flowering for optimal pod set. Avoid disturbing plants during pollination. Support with stakes if necessary.
Pod Development
3-4 weeksPods form and elongate, containing developing beans. Pods are initially green and tender, gradually becoming papery.
For fresh immature beans, harvest when pods snap easily. For dry beans, allow pods to remain on plant until completely dry and brittle.
Maturity & Harvest
1-2 weeksPods are completely dry and beige-colored. Seeds inside rattle when pods are shaken. Plant foliage browns and dries.
Harvest when pods are completely dry to prevent moisture damage. Thresh beans to separate from pods. Dry further indoors if needed before storage.

Harvest Tips
For fresh immature green beans (flageolets verts), harvest when pods are tender and snap cleanly, typically 50-60 days after planting. For dried flageolets, allow pods to mature fully on the plant until completely dry and brown, then harvest and shell. Store dried beans in airtight containers in a cool, dry place for up to 1 year. Handle carefully during harvest as dried pods are fragile.
