When Do You Plant Tomato Seeds in Missouri?

Tomatoes are one of the most popular homegrown vegetables for gardeners in Missouri. They are easy to grow, and the taste of a freshly picked tomato is unbeatable. To have a successful tomato harvest, it's important to plant the seeds at the right time. In this article, we will discuss the best time to plant tomato seeds in Missouri.

Spring Planting

The best time to plant tomato seeds in Missouri is in the springtime. The last frost in Missouri typically occurs in mid-April, making it safe to plant outdoor crops. The optimal soil temperature for planting tomato seeds is at least 60 degrees Fahrenheit. To ensure the soil has reached the correct temperature, use a soil thermometer to test the temperature at least two inches below the surface. If the soil is too cold, wait a week or two, and test the temperature again.

Indoor Planting

If you want to get a head start on your tomato crop, you can start the seeds indoors. Start the seeds six to eight weeks before the last frost of the season, which is typically mid-April in Missouri. This will give the tomato plants time to mature before planting them outdoors. Consider using a seed-starting mix because it is lighter and has better drainage than regular soil.

Transplanting

When the seedlings have grown to be around six inches tall, it's time to transplant them to your garden. Harden the plants off by gradually exposing them to outdoor temperatures and sunlight over the course of a week. When transplanting, make sure to dig deep holes, and bury the plants up to their first set of leaves. This will encourage a strong root system to develop.

Summer Planting

If you missed the spring planting season, you still have time to plant tomatoes in the summer. Plant the seeds in late May or early June for a late summer harvest. However, keep in mind that hot weather can be hard on tomato plants. Make sure to keep the soil moist, and provide shade for the plants during the hottest hours of the day.

Conclusion

In conclusion, the best time to plant tomato seeds in Missouri is in the springtime when the last frost has passed and the soil has reached 60 degrees Fahrenheit. If you want to get a head start on your crop, start the seeds indoors six to eight weeks before the last frost. Remember to transplant the seedlings when they are around six inches tall and bury them up to their first set of leaves. If you miss your chance to plant in the spring, you can still plant in the summer, but be mindful of the hot weather. Happy planting!
