When to Plant Corn

The ideal time to plant corn (Zea mays) hinges on local climate and frost dates. Generally, corn thrives in warm soil, requiring temperatures around 60-95°F (15-35°C) for germination. Planting typically commences in spring, when soil warms and frost risk abates. Early-spring planting ensures optimal growth, while late-spring planting might suit cooler regions. Wait until the soil reaches a consistent temperature before planting in colder areas to prevent poor germination. For a continuous harvest, stagger plantings every 2-3 weeks. Corn's growth cycle spans 60-100 days, so choose the planting time that aligns with your region's weather patterns to ensure a successful and bountiful harvest.
