When to Plant Tomatoes in Columbia, MO

If you're a resident of Columbia, Missouri, then you have probably heard that tomatoes are a great crop to grow in your backyard. These plump, delicious fruits are a staple in many households and add a pop of flavor to any dish. However, it's important to know when the best time to plant them is. So, when should you plant tomatoes in Columbia, MO?

The Best Time to Plant Tomatoes

In Columbia, MO, the best time to plant tomatoes is in mid-to-late May when the soil has warmed up and frost is no longer a threat. This is typically around Memorial Day weekend. You should wait until the soil temperature is at least 60°F before planting. If you plant too early, the seeds may not germinate, and if you plant too late, your plants may not have enough time to mature before the first frost hits in the fall.

Preparing Your Soil

Before you plant your tomatoes, it's important to prepare your soil. Tomatoes prefer well-draining soil with a pH between 6.0 and 7.0. You can test the pH level of your soil using a pH testing kit, which you can purchase at your local garden center. To adjust the pH level, you can add lime to increase the pH or sulfur to decrease it.

It's also a good idea to add compost or well-rotted manure to your soil to improve its fertility. This will help your tomato plants get the nutrients they need to grow healthy and strong. Be sure to mix the compost or manure evenly throughout your soil and avoid just dumping it in one spot.

Choosing Your Tomatoes

When it comes to choosing what type of tomatoes to plant, there are two main categories: determinate and indeterminate. Determinate tomatoes are bred to grow to a certain size and produce all of their fruit at once, making them good for canning and preserving. Indeterminate tomatoes continue to grow and produce fruit throughout the growing season, which makes them good for fresh eating.

Some popular varieties of tomatoes to grow in Columbia, MO include Early Girl, Brandywine, and Celebrity. Be sure to do your research and choose a variety that is well-suited for your particular climate and soil type.

Planting Your Tomatoes

When planting your tomatoes, make sure to space them about 2 to 3 feet apart to allow for good air circulation. This will help prevent diseases from spreading among your plants. Dig a hole that is deep enough to cover the entire root ball and about 1/3 of the stem. Water your plants immediately after planting to help settle the soil around the roots.

After planting, it's important to keep your tomato plants well-watered, especially during dry spells. Be sure not to water them too much, as this can lead to diseases and fungal problems. You can also add a layer of mulch around your plants to help retain moisture and prevent weeds.

Caring for Your Tomatoes

To keep your tomato plants healthy, it's important to prune them regularly. This will help promote good air circulation and prevent diseases from taking hold. You should also stake or cage your plants to help support them as they grow taller. Be sure to remove any yellowing or damaged leaves, as these can also contribute to disease problems.

Another important step in caring for your tomatoes is to fertilize them regularly. You can use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. Be sure to follow the directions on the label and avoid over-fertilizing, as this can lead to burnt roots and stunted growth.

Harvesting Your Tomatoes

Finally, it's time to harvest your tomatoes! Most varieties will mature in about 60 to 80 days from the time of planting. When your tomatoes are ripe, they should be slightly soft to the touch and have a deep, rich color. You can store your tomatoes at room temperature, but be sure not to store them in direct sunlight or they will become over-ripe and mushy.

Congratulations, you're now ready to plant and care for your own backyard tomato garden in Columbia, MO! Follow these tips and you'll be enjoying delicious, juicy tomatoes all season long.
