Factors to Consider When Determining When to Plant Corn in Minnesota

When to plant corn in Minnesota is a critical decision that can have a significant impact on the crop’s yield. There are a number of factors to consider when making this decision, including:

  • Climate: The climate in Minnesota can vary significantly from one region to another. The northern part of the state has a shorter growing season than the southern part, so corn should be planted earlier in the north. The average frost-free date in Minnesota is May 15, but this can vary depending on the year. It is important to plant corn at least two weeks before the average frost-free date to allow the crop to establish a good root system before the weather turns cold.
  • Soil conditions: The type of soil in your field will also affect the best time to plant corn. Corn does best in well-drained soils with a pH of 6.0 to 7.0. If your soil is compacted or poorly drained, it may be necessary to amend the soil before planting corn.
  • Varieties of corn: The variety of corn you choose will also affect the best time to plant. Early maturing varieties of corn can be planted earlier than late maturing varieties. Early maturing varieties typically mature in 70 to 80 days, while late maturing varieties can take up to 100 days to mature.
  • Planting date: The planting date is the date when the corn seeds are placed in the ground. The planting date is typically based on the average frost-free date and the variety of corn you are planting.
  • Growing season length: The growing season length is the number of days between the last frost in the spring and the first frost in the fall. The growing season length in Minnesota can vary from 130 to 160 days.
  • Risk of frost: The risk of frost is another factor to consider when determining when to plant corn. Corn is a frost-sensitive crop and can be damaged if the temperature drops below 32 degrees Fahrenheit. If there is a high risk of frost, it is best to plant corn later in the season.

Recommended Planting Dates for Corn in Minnesota

The following are recommended planting dates for corn in Minnesota, based on the variety of corn and the average frost-free date:

  • Early maturing varieties: May 15-June 1
  • Mid-season maturing varieties: June 1-June 15
  • Late maturing varieties: June 15-July 1

It is important to note that these are just general guidelines and the best planting date for your specific field may vary. If you are unsure of the best planting date for your field, consult with your local extension agent.

When To Plant Corn In Minnesota?

Corn is a warm-season crop that requires a long growing season to reach maturity. In Minnesota, the average frost-free date is around May 15th, so corn should be planted around 2-3 weeks before that date. This will give the corn enough time to grow and mature before the first frost.

However, the exact planting date will vary depending on your location and the weather conditions. If you live in a warmer area of Minnesota, you may be able to plant corn a little earlier. Conversely, if you live in a cooler area, you may need to wait until the weather is warmer before planting corn.
