1. Factors to Consider When Choosing a Planting Date

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

• Soil temperature. Corn seedlings need warm soil in order to germinate and grow. The ideal soil temperature for corn planting is between 55F and 65F. If the soil temperature is too cold, the seeds will not germinate properly and the seedlings will be stunted.
• Air temperature. Corn plants also need warm air temperatures in order to grow properly. The ideal air temperature for corn growth is between 65F and 85F. If the air temperature is too cold, the plants will grow slowly and may not produce a high yield.
• Frost risk. Corn is a frost-sensitive crop, and young seedlings can be killed by frost. The risk of frost varies depending on the time of year and the location in Wisconsin. In general, the risk of frost is highest in the spring and lowest in the fall.
• Length of growing season. The length of the growing season in Wisconsin varies depending on the region. In northern Wisconsin, the growing season is shorter than in southern Wisconsin. This means that corn planted in northern Wisconsin will need to mature faster than corn planted in southern Wisconsin.
• Hybrid maturity group. Corn hybrids are classified according to their maturity group. The maturity group of a hybrid indicates how long it takes the corn to mature from planting to harvest. Corn hybrids with a shorter maturity group mature faster than corn hybrids with a longer maturity group.

When choosing a planting date for corn in Wisconsin, it is important to consider all of these factors. By taking these factors into account, you can choose a planting date that will maximize your yield.

2. Recommended Planting Dates for Different Regions of Wisconsin

The following table provides recommended planting dates for corn in different regions of Wisconsin. These dates are based on the average soil and air temperatures in each region.

| Region | Recommended Planting Date |
|—|—|
| Northern Wisconsin | May 15-20 |

When to Plant Corn in Wisconsin?

The best time to plant corn in Wisconsin is between May 15 and June 1. This will give the corn enough time to mature before the first frost, which typically occurs in late September or early October.

However, the exact planting date will depend on your specific location and climate. If you live in a warmer area, you can plant corn earlier. If you live in a cooler area, you may need to wait until later in the season.

To determine the best planting date for your area, consult the USDA planting guide. This guide provides planting dates for different crops based on your USDA hardiness zone.

How to Plant Corn

Once you have determined the best planting date for your area, you can begin planting your corn. Here are the steps involved in planting corn:

1. Prepare the soil. Corn does best in well-drained soil that is rich in organic matter. If your soil is not well-drained, you can improve drainage by adding compost or sand. You can also add organic matter to your soil by planting a cover crop in the fall.
2. Sow the seeds. Corn seeds are typically planted 2 inches deep and 4 inches apart. You can plant corn by hand or by using a seed drill. If you are planting corn by hand, you can use a dibble to make a hole in the soil and drop the seed in. Cover the seed with soil and tamp it down firmly. If you are using a seed drill, follow the manufacturer’s instructions.
3. Water the seeds. Corn seeds need to be kept moist in order to germinate. Water the seeds regularly until they have sprouted.
4. Thin the seedlings. Once the seedlings have sprouted, you will need to thin them so that they are 8 inches apart. This will help to ensure that the corn plants have enough space to grow.

Fertilizer Application

Corn is a heavy feeder and requires a lot of fertilizer to produce a good crop. You should apply fertilizer to your corn crop at planting time and again at the tassel stage. The amount of fertilizer you apply will depend on the type of fertilizer you are using and the soil fertility in your area.

Irrigation

Corn is a drought-tolerant crop, but it will produce a better crop if it is irrigated during periods of drought. If you live in an area that experiences droughts, you should irrigate your corn crop during the summer months.

Troubleshooting Corn Planting Problems

There are a number of problems that can occur when planting corn. Here are some of the most common problems and how to troubleshoot them:

• Seeding too early or too late. If you plant your corn too early, the seedlings may be damaged by frost. If you plant your corn too late, the corn may not have enough time to mature before the first frost.
• Poor germination. If your corn seeds do not germinate, it may be due to a number of factors, including:
• The seeds are old or damaged.
• The soil is too cold or too dry.
• The seeds are not planted deep enough.
• Frost damage. If your corn crop is damaged by frost, the leaves may turn brown and the corn may not produce any ears.
• Insect damage. Corn is susceptible to a number of insect pests, including corn borers, armyworms, and grasshoppers. These pests can damage the corn plants and reduce yields.
• Disease damage. Corn is also susceptible to a number of diseases, including corn smut, rust, and blight. These diseases can cause the corn plants to wilt and die.

Corn is a popular crop in Wisconsin and can be a profitable crop for farmers. By following these planting tips, you can help ensure that your corn crop is successful.

When should I plant corn in Wisconsin?

The best time to plant corn in Wisconsin is from late April to early May. The ideal soil temperature for corn germination is 55 degrees Fahrenheit, and the soil should be warm and moist. Corn seedlings can be damaged by frost, so it’s important to wait until the risk of frost has passed before planting.

What kind of corn should I plant in Wisconsin?

There are many different varieties of corn that can be grown in Wisconsin. The best variety for you will depend on your climate, soil conditions, and intended use for the corn. Some popular varieties of corn for Wisconsin include:
