Growth Stages

1

Germination & Seedling

1-2 weeks

Seeds sprout within 7-10 days in warm soil. Cotyledons emerge followed by true leaves. Young seedlings are tender and vulnerable.

Keep soil warm (65-75°F) and consistently moist. Ensure adequate light to prevent leggy growth. Thin seedlings if necessary, though direct sowing is preferred.

2

Vine Establishment

2-3 weeks

Plants develop runners and begin climbing. Multiple leaflets appear, and the plant establishes its root system and climbing structure.

Provide sturdy trellising early. String, poles, or stakes work well. Gentle twining helps direct vines upward. Maintain consistent moisture and monitor for pests.

3

Flowering

2-3 weeks

Small white, pink, or light purple flowers appear along the vines in clusters. Flowering indicates pod set is imminent.

Continue watering and provide support as needed. Avoid high-nitrogen fertilizer which can promote excessive foliage at the expense of flowers. Light feeding with balanced fertilizer encourages flowering.

4

Pod Development & Snap Bean Harvest

3-4 weeks

Green pods with red and white speckles appear and rapidly lengthen. For snap beans, pods are tender, succulent, and best eaten young before seeds enlarge.

Begin harvesting snap beans when pods are 4-6 inches long, tender, and pods snap cleanly. Regular picking encourages continued production. Handle plants gently to avoid damaging vines.

5

Dry Bean Maturation

3-4 weeks

Pods dry and yellow on the vine. Seeds inside fill out completely and harden. Pods become papery and brittle when fully mature.

Allow pods to remain on vine until fully dry for storage. If heavy rains threaten, pull entire plants and hang to dry indoors. Seeds should rattle inside pods when ready.

Harvest Tips

For snap beans: Pick every 2-3 days when pods are 4-6 inches long, tender, and vibrant. Harvest while seeds inside are still small. For dried beans: Allow pods to remain on vine until fully brown and papery. Shell dried pods indoors over a container. Store dried beans in airtight containers in a cool, dry location.
