When to Plant Tomatoes in Oklahoma

Tomatoes are a popular crop for Oklahoma gardeners. However, since Oklahoma has a varied climate, it can be difficult to know exactly when to plant tomatoes. Here are some tips to help you determine the best time to plant your tomato crop.

Soil Temperature

Tomatoes prefer warm soil with temperatures between 60 and 70 degrees Fahrenheit. If the soil is too cold, the plants will not grow well and may suffer from diseases. You can measure soil temperature with a soil thermometer. If the soil temperature is below 60 degrees Fahrenheit, it is best to wait before planting tomatoes.

Frost Dates

In Oklahoma, the average last frost date ranges from early April in the south to late April or early May in the north. You should wait until after the last frost date to plant your tomato crop. Planting too early can result in damage or even death of your plants. It is also important to be prepared to protect your plants in case of a late spring frost.

Planting Indoors

If you want to get a head start on your tomato crop, you can start your plants indoors. This will allow them to get a good start before planting them in your garden. You should start your seeds indoors 6 to 8 weeks before the last frost date. When planting your seedlings outdoors, be sure to harden them off first by gradually exposing them to outdoor conditions.

Choosing Varieties

When selecting tomato varieties for your Oklahoma garden, it is important to choose varieties that will do well in your specific climate. Some good choices for Oklahoma include Early Girl, Celebrity, and Better Boy. It is also important to choose disease-resistant varieties to help prevent common tomato diseases in Oklahoma, such as Early Blight and Septoria Leaf Spot.

Planting Tips

When planting your tomato crop, be sure to choose a sunny location with well-drained soil. Tomatoes also need plenty of water, so be sure to water them regularly. Fertilize them with a balanced fertilizer, following the manufacturer's instructions. You can also use organic fertilizers, such as compost or fish emulsion.

In conclusion, the best time to plant tomatoes in Oklahoma is after the last frost date, when the soil temperature is at least 60 degrees Fahrenheit. Starting seeds indoors can give you a head start on your tomato crop, and choosing the right varieties and planting in a sunny location with well-drained soil will help your plants thrive. With proper care and attention, you can enjoy a bountiful tomato harvest in your Oklahoma garden.
