As a gardening and landscaping expert, I can provide you with detailed information on the latest date to plant corn in Missouri. According to the University of Missouri Extension’s publication 6201, sweet corn can be planted any time from the last week in April to the first of August. However, it is important to consider certain factors before deciding on the latest date to plant corn.
Corn, being a member of the grass family, thrives best when the soil temperature reaches 60 degrees Fahrenheit. Planting corn too early in cold soil can result in poor germination and slow growth. On the other hand, planting corn too late in the growing season may not allow sufficient time for the corn to reach maturity before the first frost.
In Missouri, the soil temperature typically reaches 60 degrees Fahrenheit around late April to early May. This is considered an optimal time to plant corn as it allows for a longer growing season. However, it is important to note that the weather conditions can vary from year to year, so it is recommended to monitor the soil temperature using a soil thermometer.
If the soil temperature is still below 60 degrees Fahrenheit by late April, it is advisable to wait until the soil warms up before planting corn. Planting corn in cold soil can lead to poor growth and yield. It is also important to consider the specific variety of corn you are planting, as some varieties may have different temperature requirements.
If you are planting corn in Missouri in late spring or early summer, you can expect a harvest in late summer or early fall. This timing allows for the corn to mature and be harvested before the first frost. However, if you plan to plant corn in August, it is important to choose an early maturing variety that can reach maturity within a shorter period.
In my personal experience, I have found that planting corn around mid-May in Missouri has been successful. This timing allows for the soil to warm up sufficiently and provides a longer growing season for the corn to reach maturity. However, it is always best to monitor the soil temperature and consider the specific variety you are planting to ensure optimal growth and yield.
To summarize, the latest date to plant corn in Missouri can vary depending on the soil temperature and the specific variety of corn. It is generally recommended to plant corn when the soil temperature reaches 60 degrees Fahrenheit, which typically occurs around late April to early May in Missouri. However, it is important to monitor the weather conditions and choose an appropriate variety that can reach maturity before the first frost.
