| Start Indoors | Not recommended; roots sensitive to transplanting. Best results occur when seedlings are transplanted less than 2 weeks old. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is at least 60°F; ideally 65°–90°F. |
| Growing & Harvesting | Corn is ready about 3 weeks after the silks appear. Harvest when the silks are brown, but not dried, and the husks are dark green; ears should be plump, and rounded rather than pointed at the tip. To test for ripeness, gently pull back the husk and pop a kernel; the liquid should be whitish; if it is still clear, ears are not quite ready. |
