What Climate and Growing Conditions Does Corn Require?

Corn, one of the world’s most important food crops, is a member of the grass family and is grown throughout the world. Corn is a warm-season crop that requires certain environmental conditions in order to achieve optimal growth and yield. To maximize your corn harvest, it is important to have an understanding of the climate and growing conditions corn requires.

Climate and Temperature

Corn is a warm-season crop and requires temperatures above 60°F (15°C) for successful germination and growth. It is best to wait until soil temperatures reach at least 60°F (15°C) before planting. In the northern hemisphere, corn is typically planted in the spring after the average soil temperature has reached this level. In the southern hemisphere, corn is planted in the fall when temperatures are above 60°F (15°C).

Corn grows best in warm weather and does not tolerate cold temperatures. Seedling corn can be killed by temperatures below 40°F (4°C). Temperatures above 95°F (35°C) can also be damaging to corn plants.

Soil and Fertility

Corn is a heavy feeder and requires fertile, well-drained soil with a pH between 5.5 and 7.0. The soil should also have adequate levels of potassium, phosphorus, zinc, and nitrogen. In addition, the soil should be relatively free of weeds and diseases.

To ensure the soil meets these requirements, it is important to test the soil prior to planting. A soil test will tell you if the soil needs to be amended with additional nutrients or if the pH needs to be adjusted.

Water and Irrigation

Corn requires a consistent supply of water throughout its growing season in order to reach its full potential. Corn plants need at least 1-1.5 inches (2.5-3.8 cm) of water per week in order to grow properly. The amount of water needed will depend on the soil type, temperature, and other environmental factors.

If your area experiences periods of drought, you may need to irrigate your corn crop in order to ensure it receives adequate water. The best way to irrigate corn is with a drip or overhead sprinkler system.


Corn is a sun-loving plant and requires a lot of light in order to grow properly. Corn plants should receive at least 6-8 hours of sunlight per day in order to reach their full potential. Planting corn in an area that receives full sun is essential for optimal growth and yield.


Corn is a warm-season crop that requires specific environmental conditions in order to reach its full potential. Corn needs temperatures above 60°F (15°C), fertile soil with adequate levels of nitrogen, phosphorus, zinc, and potassium, a consistent supply of water, and plenty of sunshine. Understanding the climate and growing conditions corn requires will help ensure you have a successful harvest.
