A warm-season legume grown for its edible pods and seeds. Beans are fast-growing and productive, thriving in full sun with consistent moisture and moderate warmth.

Why grow it

Common beans fix nitrogen in soil, improving fertility for subsequent crops without synthetic fertilizer input. They mature faster than many other legumes (typically 50-60 days to harvest), making them practical for shorter growing seasons or succession planting within a single year. Unlike some perennial nitrogen-fixers, beans are easy to terminate and work into garden beds once productivity declines.

Watch out for

Bean plants are sensitive to cool soil temperatures and frost; sowing before soil reaches 60°F (16°C) results in poor germination and seed rot. Extended wet conditions, particularly during flowering and pod fill, can promote fungal diseases like anthracnose and bean rust, so adequate spacing and air circulation help reduce problems. Beans require consistent watering during the growing season, as water stress at flowering reduces yields significantly.
