Prepare loose, well-drained soil with a pH between 6.2 and 6.8 before planting. As a warm-season crop, you must wait until after the last spring frost when soil temperatures are consistently warm; do not sow early. Sow seeds directly into the ground at a depth of about one inch. Expect germination to occur within six to nine days under these ideal conditions. Space plants ten to twelve inches apart in rows, ensuring adequate room for air circulation. Provide consistent moisture throughout the growing season, as corn requires high water levels, especially during pollination. Apply mulch around the base to retain soil moisture and suppress weeds, but avoid piling it against the stalks. Watch for pests like corn earworm, European corn borer, and raccoons, which can damage ears; use row covers or netting if possible. Monitor for diseases such as northern corn leaf blight and Stewart's wilt by ensuring good airflow. Harvest the ears seventy-five to eighty days after planting when kernels are fully formed.When to Plant Trinity
