When to Plant Tomatoes in Missouri 2020

Tomatoes are one of the most popular vegetables grown in home gardens throughout Missouri. They are easy to grow and provide a bountiful harvest when cared for properly. However, in order to maximize your tomato crop, you need to know when to plant them. Here is everything you need to know about planting tomatoes in Missouri in 2020.

Climate Considerations

Missouri has a varied climate, and the best time to plant tomatoes varies depending on the region. In general, the state has a humid continental climate, with hot summers and cold winters. Frost is also a concern in many areas.

If you live in southern Missouri, you can plant tomatoes as early as mid-April, while in the northern part of the state, you should wait until mid-May to avoid frost damage. If you are unsure about when to plant, consult your local extension office for specific recommendations for your area.

Soil Preparation

Before planting your tomatoes, it’s important to prepare the soil properly. Tomatoes thrive in well-draining soil that is rich in organic matter. After choosing a sunny location, work compost or well-rotted manure into the soil to improve fertility and drainage.

It’s also important to maintain a soil pH of around 6.0 to 6.8 for optimal growth. Soil tests are a great way to determine your soil’s pH and nutrient levels, and can be done through your local extension office.

Planting Techniques

Once your soil is properly prepared, it’s time to plant your tomatoes. Start by digging a hole that is twice the size of the root ball of your plant. Remove any lower leaves from the stem, and gently place the plant into the hole. Backfill the hole with soil and water thoroughly.

For determinate varieties, it’s best to space plants 2-3 feet apart. Indeterminate varieties should be spaced 3-4 feet apart, with a trellis or other support system in place for climbing.

Care and Maintenance

Once your tomatoes are in the ground, they will need regular care and maintenance to ensure a bountiful harvest. Be sure to water deeply and consistently, as tomatoes require approximately 1-2 inches of water per week.

Fertilize your tomatoes with a balanced fertilizer every four to six weeks, and use mulch to suppress weeds and maintain optimal soil moisture levels. Monitor for pests and disease, and address any problems quickly.

Harvesting Tomatoes

Tomatoes are typically ready for harvest 75 to 85 days after planting, depending on the variety. When ripe, they will be firm yet slightly yielding to the touch, and deep in color. Always use a pair of scissors or pruning shears to harvest tomatoes, and aim to pick them before they become overripe.

In conclusion, planting tomatoes in Missouri is a great way to enjoy fresh and flavorful produce from your own backyard. By following the above guidelines for planting and care, you can expect a bountiful tomato harvest in the summer months.
