How to Space Corn in Ohio

Gardeners can begin planting corn in Ohio by mid-April to early May -- whenever the soil is at least 50 degrees Fahrenheit -- at a depth of 4 to 6 inches. This ensures that the corn seed has a warm environment for germination and reduces the risk of frost killing off the seedlings. Corn is a cross-pollinating plant, meaning that it needs to be planted in blocks of rows so the wind can blow pollen from one plant to the next. Planting the corn in rows requires proper spacing of the plants so that each plant has plenty of room to grow, while still keeping other plants close enough for pollination.

Instructions

- 1
  Till your garden soil to prep it for planting. Mix in any topsoil, compost or fertilizers you prefer.
- 2
  Measure out rows for the corn at 30 inches apart. You'll want to grow corn in multiple rows to encourage cross-pollination. Plant at least three rows of corn at a time. Use a chalk line or small stick at either end of each row to mark it.
- 3
  Plant two to three seeds in a single spot, about two inches deep in the ground. Cover seed with soil. Don't tamp it down.
- 4
  Plant spots about 8 to 12 inches apart in each row. Use a tape measure to be accurate.
- 5
  Thin out the seedlings in each spot when the seeds germinate and start growing. Leave only the strongest of the two or three seedlings in each spot.
