Germination & Emergence
7-14 daysSeeds sprout and seedlings emerge with cotyledons (seed leaves) above soil
Keep soil moist but not waterlogged. Ensure soil temperature is 60°F or higher for germination. Provide full sun once emerged.
Vegetative Growth
3-4 weeksPlants develop true leaves, establish root systems, and grow bushy or climbing foliage depending on variety
Water consistently, provide support for climbing varieties, thin seedlings if overcrowded. Apply light fertilizer if soil is poor.
Flowering
2-3 weeksWhite, pink, or purple flowers appear in clusters along the plant. Bees pollinate the flowers.
Maintain consistent moisture, reduce nitrogen fertilizer, avoid overhead watering to prevent flower drop. Monitor for pests.
Pod Development & Fruiting
3-4 weeksFlowers fade and small green pods begin forming and enlarging. Pods contain developing beans inside.
Continue consistent watering without waterlogging. Support heavy pod loads on climbing varieties. Reduce water as pods mature.
Maturation & Drying
2-3 weeksPods dry and turn brown/tan, beans inside harden and rattle when shaken. Leaves may yellow and drop.
Reduce watering significantly. Leave pods on plant to fully dry if weather permits, or harvest when dry-snap stage begins.

Harvest Tips
For dry beans: Harvest when pods are completely dry and brittle, usually 2-3 weeks after flowering ends. Pull entire plant or pick individual pods. Shell beans by hand or in batches, store in cool dry place. For fresh green beans: Harvest when pods snap easily, typically 60-70 days after planting, before seeds fully develop.
