When to Plant Tomatoes in Southern Wisconsin

Tomatoes are a popular plant to grow in home gardens. Southern Wisconsin has a climate that is suitable for growing tomatoes. However, planting at the right time is crucial for a successful harvest. In this article, we will discuss the best time to plant tomatoes in Southern Wisconsin.

Factors to Consider

There are several factors to consider when deciding when to plant tomatoes in Southern Wisconsin. The first factor to consider is the average last frost date. This is the date after which there is a low probability of a frost occurring. In Southern Wisconsin, the average last frost date is around May 10. It is important to wait until after the last frost date to plant tomatoes.

The second factor to consider is the soil temperature. Tomatoes require warm soil to germinate and grow. The ideal soil temperature for planting tomatoes is between 60-70°F. In Southern Wisconsin, the soil usually reaches this temperature around mid-May.

Early Planting

Some gardeners may want to plant their tomatoes earlier than mid-May. This can be done by using season extenders such as row covers, hot caps, or greenhouses. These methods can help warm the soil and protect the plants from frost. However, it is important to note that although these methods can help extend the growing season, planting too early can result in stunted growth and poor fruit production.

Late Planting

On the other hand, some gardeners may want to plant tomatoes later in the season. This can be done up until early July in Southern Wisconsin. However, late planting can result in lower yields and smaller fruits. Late planting can also result in the plants not reaching their full potential before the first frost of the season.

Choosing Tomato Varieties

When choosing tomato varieties to plant in Southern Wisconsin, it is important to consider the number of days to maturity. This is the length of time between planting and harvesting. Generally, tomato varieties that have a shorter number of days to maturity are better suited for the short growing season in Southern Wisconsin. Some recommended tomato varieties for Southern Wisconsin include Early Girl, Stupice, and Rutgers.

In Conclusion

Planting tomatoes in Southern Wisconsin can be a rewarding experience. By considering the factors mentioned above and choosing the appropriate tomato varieties, you can have a successful harvest. In general, mid-May is the best time to plant tomatoes in Southern Wisconsin for optimal growth and fruit production. Whether you choose to plant earlier or later, always monitor soil and weather conditions to ensure a healthy and fruitful harvest.
