Growing notes

Green beans want even, consistent moisture — about an inch of water per week, and more in heat or while pods are filling. Water deeply at the base once or twice a week rather than a daily sprinkle; this encourages deep roots and steadies plants against dry spells. Keep the foliage as dry as possible and water in the morning to limit rust and other leaf diseases. The most critical windows are flowering and pod-fill: drought stress at bloom makes flowers drop and pods come out short, tough, and stringy. A 2–3 inch straw or shredded-leaf mulch holds moisture and keeps soil temperatures even. Containers dry quickly and may need water daily at the height of summer.
