When to Plant Tomato Seeds in Houston

Tomatoes are fun and easy to grow in Houston, Texas, but the key to a thriving garden lies in knowing when to plant the seeds. Understanding the South Texas climate and taking the time to properly prepare the soil can ensure you grow juicy, flavorful tomatoes all season long.

Starting Seeds Indoors

Starting tomato seeds indoors is the best way to get a jump start on the tomato growing season, particularly for indeterminate varieties. Plant seeds in late winter, around six to eight weeks before the last expected frost date in Houston, which typically falls between February 14 and February 28. Keep the seedlings indoors in a well-lit, temperature-controlled environment until after the last frost.

Planting Outside

Once the soil has warmed up and the weather is consistently warm, it's time to transplant the seedlings outside, which typically falls between mid-March and early April in Houston. The soil temperature should reach at least 55F at the time of planting, which is important for root development. Choose a sunny location, with well-draining soil, that is protected from harsh winds.

Soil Preparation and Fertilizing

Preparing the soil is essential to growing healthy tomato plants. Enrich the soil with organic matter and compost to improve its texture and nutrient content. Avoid planting in areas that have recently grown tomatoes, peppers, or eggplant as these plants share similar pests and diseases. You can also add a slow-release fertilizer, such as Espoma Tomato-tone, to the soil to provide the necessary nutrients for optimal growth.

Maintenance

Once the tomato plants are established, they require regular care and maintenance. Keep the soil moist, but not overly watered, to prevent root rot. Support the plants with stakes or a trellis to keep them upright and help prevent stem breakage. Prune the plants to help manage growth and promote air circulation to prevent diseases.

Conclusion

By understanding the ideal planting window for tomato seeds in Houston, preparing the soil with plenty of organic matter, and providing proper care and maintenance, you can have a successful tomato garden all season long. With a little bit of TLC, you'll be enjoying delicious and nutritious home-grown tomatoes in no time.
