How long does it take corn to grow and produce ears?
Corn requires from 60 to 100 days to reach harvest depending on the variety and warm weather. Corn is ready for harvest when ears turn dark green, silks turn brown, and kernels are soft and plump; squeeze a kernel and the juice will be milky not clear.
Drain the seeds in the morning and give them a fresh rinse in cool water. Cover them with a damp paper towel to conserve moisture, and continue rinsing them at least three times daily until they germinate. In roughly two to five days, a small root will emerge from each kernel; it's planting time.
- Parts. The kernel of maize consists of a pericarp (fruit wall) fused to the seed coat. This type of fruit is typical of the grasses and is called a caryopsis. Maize kernels are frequently and incorrectly referred to as seeds.
- Let them dry in a single layer for a couple more weeks. If the kernels are still a bit moist, they can mold in storage, so you want to make sure to dry them well. At this stage, the kernels will have corn silk and bits of cob mixed in with them.
- Planting Sweet Corn. When planting sweet corn, plant the seeds 1/2 inch deep in cool, moist soil, and at least 1 to 1 1/2 inches deep in warm, dry soil. Plant 12 inches apart with at least 30 to 36 inches between rows. This protects the plants from cross-pollination if you have planted different varieties.
