When to Plant Tomatoes in OK

If you're a gardener in Oklahoma, you're probably wondering when is the best time to plant tomatoes. The good news is that Oklahoma is in USDA Hardiness Zone 7, which means the state has a relatively long growing season compared to other parts of the country. Here are some factors to consider when deciding when to plant tomatoes in OK:

Average Last Frost Dates

The average last frost date in Oklahoma typically ranges from late March to early May, depending on the location. This is an important factor to consider when determining when to plant tomatoes, as they are sensitive to cold temperatures and can be damaged or killed by frost. To avoid the risk of frost damage, it's recommended to wait until after the last frost date to plant tomatoes in OK.

Soil Temperature

The temperature of the soil is another important factor to consider when planting tomatoes in OK. Tomatoes prefer warm soil with a temperature between 60 and 70 degrees Fahrenheit. If the soil temperature is below 60 degrees, the plants will grow slowly and may even develop root rot. To ensure optimal growth and yield, it's important to plant tomatoes when the soil has warmed up to at least 60 degrees.

Early Planting

Some gardeners in OK may be tempted to plant tomatoes early in the season to get a head start on their growth. However, planting too early can be risky as frost can still occur and damage the plants. Using protective measures such as row covers or cloths can help mitigate some of the risks, but it's generally recommended to wait until after the last frost date to plant tomatoes in OK.

Seedlings vs. Transplants

When planting tomatoes in OK, gardeners have the option of using seedlings or transplants. Seedlings are plants grown from seed and can take longer to mature, while transplants are already established and can be planted directly into the ground. If using seedlings, it's recommended to start them indoors 6-8 weeks before the last frost date to give them ample time to mature. Transplants can be planted directly into the ground after the last frost date.

Conclusion

In summary, the best time to plant tomatoes in Oklahoma is after the last frost date when the soil temperature has warmed up to at least 60 degrees Fahrenheit. Using seedlings or transplants is up to personal preference, but both options can thrive in the state's long growing season. By following these guidelines, gardeners in OK can enjoy a bountiful tomato crop in the summer months.
