What is the recommended seeding date for corn?

The recommended seeding date for corn, particularly in Ontario, is typically in early May. This timing is essential because corn is sensitive to soil temperature and requires sufficiently warm conditions for optimal germination and early growth. Planting in early May allows the soil to reach temperatures that promote faster emergence, minimizes the risk of frost damage, and ensures that the growing season is maximized.

Seeding too early, as in early April, can expose the young corn plants to cold soil temperatures and potential frost, both of which stall growth or can damage plants. Conversely, planting too late, such as in late May, risks not allowing enough time for the corn plants to mature before the first frost in fall, which can lead to reduced yields and lower quality crops. Therefore, early May strikes a balance, aligning with both agronomic potential and environmental conditions to optimize corn production.
