When To Plant Tomatoes In Houston?

Tomatoes are a popular crop for home gardeners, and with Houston’s long growing season, the opportunities for growing a successful tomato crop are plentiful. Knowing when to plant tomatoes in Houston, the right varieties to choose, and how to care for them can help ensure a bountiful harvest.

When To Plant Tomatoes In Houston?

Tomatoes in Houston can be planted during two primary periods: early spring and late summer. Houston’s climate typically allows for a long growing season, which can start as early as February and last until the first frost, often in December. Spring-planted tomatoes are usually put in the ground in late February to early March, once the danger of frost has passed.

For a fall crop, you should plant tomatoes in late July to early August. The fall planting allows the plants to mature and produce fruit before the first expected fall frost. This timing also takes advantage of the typically cooler and less humid fall weather, which can be beneficial for tomato growth.

Can You Grow Tomatoes In Houston?

Yes, you can indeed grow tomatoes in Houston. The city’s long growing season and generally mild winter temperatures provide ample opportunities to grow a successful crop. Houston’s climate is well-suited to growing tomatoes, provided they receive adequate care and protection from extreme summer heat.

However, it’s important to select the right variety of tomato for the area. Varieties that are heat-tolerant and resistant to common diseases fare well in Houston. Some of the recommended varieties for Houston include ‘Celebrity’, ‘Heatwave’, ‘Better Boy’, and ‘Cherry’ tomatoes.

What Is The Best Time To Start Tomato Seeds Indoors In Houston?

The best time to start tomato seeds indoors in Houston is typically 6-8 weeks before the last frost date. For Houston, this usually means starting seeds in late December or early January for the spring planting season. This allows the seedlings enough time to grow strong before they’re transplanted outdoors.

For a fall crop, seeds should be started indoors around May or early June. Keep in mind that seedlings will need a warm, sunny location to grow, or you might need to use grow lights if natural sunlight is inadequate. Once the seedlings have grown two sets of true leaves, they can be transplanted to larger pots until they are ready to move outdoors.

When Is The Last Frost Date In Houston For Planting Tomatoes?

In Houston, the last frost date usually occurs between late January and early February. However, this can vary from year to year based on specific weather conditions. It’s crucial to wait until after the last frost date before planting tomatoes, as a sudden frost can damage or kill young plants.

Once the last frost has passed, and soil temperatures have consistently reached above 60°F (15.5°C), it’s typically safe to plant tomatoes. Remember to harden off your seedlings before planting them outdoors, gradually acclimating them to outdoor conditions over a week or so.

How Often To Water Tomatoes In Houston?

Tomatoes in Houston should be watered deeply but infrequently, typically once every three to five days depending on weather conditions. It’s best to water in the early morning, which allows the water to soak into the ground before the heat of the day evaporates it. Additionally, watering in the morning helps to prevent fungal diseases that can be encouraged by damp leaves overnight.

In the heat of the summer, you may need to water more frequently, but always check the soil first. The top inch or two should be dry before watering again. Using mulch around your plants can help conserve moisture and maintain more consistent soil moisture levels.

What Sunlight Do Tomatoes Need In Houston?

Tomatoes need full sun to produce a good crop, which equates to at least six to eight hours of direct sunlight each day. In Houston’s sunny climate, this is typically easy to achieve. However, during the hottest part of the summer, some afternoon shade can actually be beneficial to prevent the plants from getting too hot and stressed.

Planting in a location that gets morning sun and some afternoon shade can be an ideal situation in Houston. This allows the plants to receive the necessary sunlight for photosynthesis but reduces the risk of heat stress during the hottest part of the day.

What Are The Recommended Tomato Varieties For Houston?

Several tomato varieties are well-suited to Houston’s climate. ‘Celebrity’ is a popular choice, known for its resistance to common tomato diseases and its ability to handle Houston’s heat. ‘Heatwave’ is another suitable variety, as it’s specifically bred to perform well in high temperatures.

‘Better Boy’ is a heat-tolerant variety that produces large, flavorful fruits, while ‘Cherry’ tomatoes can handle the heat and are excellent for salads or snacking. Other good options include ‘Solar Fire’, ‘Phoenix’, and ‘Sunmaster’, all bred for hot climates and ideal for Houston’s long growing season.

How Long Does It Take For Tomatoes To Mature In Houston?

The time it takes for tomatoes to mature in Houston varies depending on the variety and the specific growing conditions each year. On average, tomatoes take between 60 to 100 days to mature from the time they’re transplanted into the garden. Early-season varieties can mature in as little as 60 days, while late-season varieties can take up to 100 days.

This means if you plant in early March, you could start seeing ripe tomatoes as early as May or June. For the fall crop planted in late July or early August, expect ripe tomatoes in October or November, again depending on the specific variety and growing conditions.

How To Protect Tomato Plants From Houston’s High Heat And Humidity?

Protecting your tomato plants from Houston’s high heat and humidity involves several strategies. Firstly, choose heat-tolerant varieties that can handle these conditions. Regular watering is critical, as is mulching around the base of the plants to conserve moisture and reduce soil temperatures.

During periods of extreme heat, you can also provide shade to your tomato plants during the hottest part of the day. This can be achieved with shade cloth, which allows light through but blocks some of the heat. Ensure good air circulation around your plants to help prevent disease, and keep a close eye on your plants for any signs of heat stress or disease, addressing any issues promptly to maintain healthy, productive plants.

Conclusion: When To Plant Tomatoes In Houston

In conclusion, growing tomatoes in Houston is feasible due to the city’s long growing season and mild winter temperatures. The best times to plant tomatoes in Houston are during early spring and late summer, with specific planting dates varying based on the last frost date and the desired harvest time. Starting tomato seeds indoors 6-8 weeks before the last frost date is recommended, and selecting heat-tolerant and disease-resistant varieties is crucial for success.

Tomatoes require full sun for at least 6-8 hours each day, but some afternoon shade can be beneficial during the hottest months. Proper watering practices, such as deep and infrequent watering, and protecting plants from Houston’s high heat and humidity through shading, mulching, and air circulation, are essential for optimal growth. With proper care, tomato plants can produce mature fruits within 60 to 100 days after transplanting, depending on the variety and growing conditions. By following these guidelines, Houston gardeners can enjoy a bountiful tomato harvest throughout the growing season.
