Germination & Seedling
2-3 weeksSeeds sprout and develop cotyledons. Small plants with simple compound leaves emerge. Growth is relatively slow initially.
Keep soil consistently moist but not waterlogged. Protect from frost if early planted. Thin seedlings to proper spacing by week 3-4.
Vegetative Growth
3-4 weeksPlants develop robust stems, multiple branches, and compound pinnate leaves. Growth accelerates as days lengthen. Plants reach 2-4 feet in height.
Support tall plants with stakes or trellising to prevent lodging. Monitor for aphids. Provide consistent water. Apply light compost mulch to retain moisture and suppress weeds.
Flowering
2-3 weeksBeautiful white or cream flowers with dark purple or black markings appear in clusters along the stems. Flowers are attractive and bee-friendly.
Reduce watering frequency as flowering begins; keep soil moist but not wet. Ensure good air circulation to prevent powdery mildew. Let bees naturally pollinate. Dead-head any diseased flowers immediately.
Pod Development & Fruiting
3-4 weeksFlowers develop into thick, leathery green pods containing large beans. Windsor pods are typically 6-8 inches long and can hold 4-8 large beans each.
Continue moderate watering. Ensure good spacing for air flow. Monitor for spider mites and bean beetles. Support heavy pod-laden branches.
Harvest Ready
1-2 weeks peak harvest windowPods reach full size and beans fill the pod. Pods may begin to pale slightly, though harvest is typically done when pods are still green and fully sized.
Pick pods regularly to encourage continued production. Handle plants gently to avoid breaking branches. Harvest in early morning when beans are crisp.

Harvest Tips
Harvest pods when they are full-sized and bright green, typically 70-100 days after sowing. Pods should be tender and beans fully formed but still plump. Harvest by pinching or cutting the pod stem to avoid damaging the plant. For eating fresh, pick before the beans become hard. For drying and storage, allow pods to mature fully, turn brown, and dry on the plant, then shell and store in a cool, dry place. Regular picking encourages continued flowering and production.
