If you live in Southern Missouri, it’s recommended that you plant your tomato plants outside between the 20th of April and the 15th of May. In Central Missouri, the suggested planting dates are slightly later due to the later last frost day. You can plant tomato plants or seedlings out between the 5th and 20th of May. While in Northern Missouri, the 10th to the 20th of May is the best time to plant tomatoes outside.

Missouri Tomato Planting Dates

Many people start their tomatoes inside under grow lights to get them off to a good start. That means they would be planting out after about May 10 or 11 if they started on March 1st, under optimal conditions.

You can plant the tomato seeds in a pot and cover them with plastic wrap or a plastic bag. This creates a micro-climate that will keep the seeds warm and moist while they germinate. Once the young seedlings have started to grow, you can uncover the plant. Your plants can then be moved outdoors after the risk of frost has passed. You may need to acclimatize your tomato plants by moving them outside during the day and bringing them in at night, for a few days, before leaving them outside full time.


In summary, check out local weather patterns, get your tomatoes from a very reputable source, and plant them in the early spring. If you want to get a head start on the growing season, you can start them inside 4 to 6 weeks before the average last frost date.
