Tomatoes are one of the most popular garden vegetables in Texas. They are loved for their fresh, homegrown flavor and versatility in the kitchen. They are an excellent source of vitamins A and C, making them a nutritious addition to any meal.
Growing your own tomatoes can be a rewarding experience, whether you enjoy them in salads, sandwiches, or homemade sauces. However, successful tomato gardening requires proper site selection, soil preparation, and ongoing care.
Central Texas’s hot summers and unpredictable weather can pose challenges, but with the right variety selection and proper techniques, you can enjoy an abundant tomato harvest. This guide will walk you through everything you need to know, from choosing the best varieties for Texas conditions to planting, caring for, and harvesting your tomatoes.
Choosing the Right Tomato Variety
Selecting the right tomato variety is key to a successful harvest, especially in the hot and sometimes unpredictable climate of Central Texas. Tomatoes come in different sizes, flavors, and growth habits, so choosing a variety that thrives in local conditions will make a big difference.
Small-Fruited Varieties
Small-fruited tomatoes tend to mature quickly, produce abundant harvests, and are perfect for snacking, salads, and container gardening. Some great options include:
Baxter’s Early Bush – An early-producing variety with compact growth.
Cherry Grande – A classic cherry tomato known for its sweet and juicy flavor.
Juliet – A small Roma-type tomato that resists cracking and is great for roasting.
Red Cherry – A productive plant that yields bright red, bite-sized fruit.
Small Fry – Known for its vigorous growth and heavy yields.
Large-Fruited Varieties
Larger tomatoes are ideal for slicing, cooking, and making fresh sauces. These varieties take a bit longer to mature but produce flavorful, meaty fruit. Popular choices include:
Better Boy – A high-yielding hybrid with excellent disease resistance.
Big Beef – Produces large, juicy tomatoes with rich flavor.
Big Box – A reliable variety with firm texture and excellent taste.
Bush Beefsteak – Compact yet produces hefty, flavorful fruit.
Carnival – A vigorous grower with firm, meaty tomatoes.
Celebrity – A favorite among Texas gardeners due to its resilience and great taste.
Homestead – Well-suited for Texas heat, producing large, firm fruit.
When choosing a variety, consider disease resistance, growth habit (determinate vs. indeterminate), and your intended use (fresh eating, cooking, or preserving).
Site Selection & Soil Preparation
Tomatoes thrive when planted in the right location and in well-prepared soil. Choosing an optimal site and improving soil quality will set the foundation for strong, healthy plants and a productive harvest.
Best Growing Conditions
To ensure the best growth and fruit production, plant tomatoes in a location that meets the following criteria:
Full Sun: Tomatoes need at least 6-8 hours of direct sunlight daily. More sun typically leads to better fruit development and fewer disease issues.
Well-Draining Soil: Avoid areas where water collects after heavy rains. Raised beds or containers can help improve drainage in problem areas.
Good Air Circulation: Space plants properly to allow airflow, which helps prevent disease. Avoid planting tomatoes too close to fences, walls, or other plants that may block air movement.
Crop Rotation: Avoid planting tomatoes in the same spot where tomatoes, peppers, or eggplants have grown in the past two years. Rotating crops helps prevent soilborne diseases.
Soil Preparation
Healthy soil is the key to vigorous tomato plants. Follow these steps to prepare your garden bed:
Loosen the Soil: A few weeks before planting, work the soil 8-10 inches deep using a shovel or tiller. This improves root penetration and drainage.
Remove Debris: Clear out rocks, weeds, and any leftover plant material from previous seasons.
Add Organic Matter: Mix in 2-3 inches of compost, well-rotted leaves, or aged manure to improve soil structure and fertility. Organic matter helps retain moisture while ensuring good drainage.
Fertilize Properly: Before planting, apply 2-3 pounds of balanced fertilizer per 100 square feet, mixing it into the top few inches of soil. This provides essential nutrients for initial growth.
Consider Raised Beds: If your soil has drainage issues or is heavy clay, raised garden beds can provide better growing conditions. Raised beds warm up faster in the spring, which can lead to earlier harvests.
Taking the time to prepare your soil will result in stronger plants and better fruit production throughout the season.
Planting Tomatoes
Proper planting techniques can make a big difference in the health and productivity of your tomato plants. Whether you're planting in the ground, raised beds, or containers, following these guidelines will help ensure strong root development and a bountiful harvest.
When to Plant
The best time to plant tomatoes in Central Texas depends on the season:
Spring Planting: Set out transplants after the last frost, typically between March and early April.
Fall Planting: For a fall harvest, plant tomatoes about 100 days before the first expected frost, usually in late July to early August.
Avoid planting too early in the season, as cold temperatures can stunt growth, and too late, as extreme heat can interfere with fruit setting.
Transplanting Guidelines
When planting tomatoes, follow these steps to ensure they establish well:
Choose Healthy Transplants: Select 6-8 inch tall plants with thick stems and dark green leaves. Avoid plants that are yellowing or have leggy growth.
Dig the Right Hole:
For single-planting, dig a hole 2 feet wide and 10 inches deep.
For row planting, space holes 3-4 inches deep and 2-4 feet apart depending on the support method.
Pre-Water the Holes: Fill each hole with water before planting, allowing it to soak in to ensure the roots stay hydrated.
Plant Deep for Stronger Roots:
Bury part of the stem to encourage additional root growth. If your plant is leggy, plant it horizontally, leaving only the top leaves above the soil.
Backfill and Firm the Soil: Pack the soil gently around the plant, leaving a slight depression around the base to help hold water.
Water Immediately: After transplanting, give plants a deep watering to help reduce transplant shock.
Spacing Considerations
Staked or caged plants: Space 3 feet apart in rows.
Unsupported plants: Space 4-5 feet apart to allow for sprawling growth.
Transplanting tomatoes in the evening or on a cloudy day can help minimize stress and give plants a better start.
Caring for Tomato Plants
Once your tomatoes are planted, proper care throughout the growing season will ensure healthy plants and a productive harvest. Providing the right amount of water, fertilizer, and support will help your tomatoes thrive in Central Texas' climate.
Watering
Tomatoes need consistent moisture to develop strong roots and produce high-quality fruit.
Follow these watering guidelines:
Water deeply and slowly to encourage deep root growth. Aim for 1-2 inches of water per week, depending on rainfall.
Avoid overhead watering to reduce the risk of fungal diseases. Instead, water at the base of the plant.
Mulch around plants with 2-3 inches of organic material (such as compost, straw, or leaves) to retain moisture and suppress weeds.
Check soil moisture by inserting your finger 2 inches into the soil—if it's dry at that depth, it's time to water.
Fertilizing
Tomatoes are heavy feeders and need the right balance of nutrients throughout their growth cycle.
Before planting: Apply 2-3 pounds of a balanced fertilizer per 100 square feet and mix it into the topsoil.
After planting:
Side-dress with 1 tablespoon of fertilizer per plant every 3-4 weeks to maintain steady growth.
Apply fertilizer 6 inches away from the stem and gently work it into the soil, followed by deep watering.
Avoid excessive nitrogen, which can lead to excessive foliage growth and fewer fruits.
Supporting Tomato Plants
Providing support for tomato plants prevents disease, reduces fruit rot, and makes harvesting easier.
Staking Method
Insert 6-foot stakes 10 inches deep next to each plant.
Tie the plant loosely to the stake every 12 inches as it grows, using soft ties like strips of cloth or garden twine.
Regularly prune suckers (small shoots that form between the main stem and branches) to encourage larger fruit production.
Caging Method
Use a sturdy wire cage (5-6 feet tall and 2 feet in diameter) to surround the plant.
Place the cage over the plant early in the season before it grows too large.
Caged tomatoes do not need pruning, as the cage supports the natural bushy growth.
Choosing the right support system will depend on the variety you are growing and your space availability.
Common Tomato Pests & Diseases
Tomatoes are prone to pests and diseases, especially in the warm climate of Central Texas. Keeping an eye on your plants and taking preventive measures can help ensure a healthy and productive crop.
Common Pests
Several insects can damage tomato plants by feeding on leaves, stems, or fruit. Here’s how to identify and control them:
Flea Beetles
Signs of Damage: Tiny holes in leaves, giving them a “shotgun” appearance.
Control Methods:
Use floating row covers to protect young plants.
Apply diatomaceous earth or neem oil as organic control options.
Use insecticides like Sevin if infestations become severe.
Hornworms
Signs of Damage: Large, green caterpillars with white stripes, often found devouring leaves and fruit.
Control Methods:
Handpick and remove them manually.
Introduce beneficial insects like parasitic wasps, which lay eggs inside the hornworms.
Apply Bacillus thuringiensis (Bt), an organic caterpillar control.
Whiteflies
Signs of Damage: Tiny white insects flying around the plant when disturbed; yellowing leaves.
Control Methods:
Use yellow sticky traps to catch adult whiteflies.
Spray plants with neem oil or insecticidal soap every few days.
Encourage natural predators like ladybugs and lacewings.
Common Diseases
Fungal and bacterial diseases are common in tomatoes, especially in humid or overwatered conditions. Here’s how to identify and manage them:
Blossom-End Rot
Signs of Damage: Black or brown sunken spots on the bottom of the fruit.
Causes: Calcium deficiency and inconsistent watering.
Prevention:
Keep soil moisture consistent—don’t let it dry out completely.
Avoid excessive nitrogen, which can interfere with calcium uptake.
Add crushed eggshells or calcium-based fertilizers if needed.
Early Blight
Signs of Damage: Yellowing lower leaves with dark brown, target-like spots.
Causes: A fungal disease spread by moist conditions and poor air circulation.
Prevention:
Water at the base of the plant rather than overhead.
Mulch to prevent soil from splashing onto leaves.
Remove infected leaves and apply copper fungicide if necessary.
Wilt Diseases (Fusarium & Verticillium Wilt)
Signs of Damage: Leaves wilt and turn yellow, even when the plant is well-watered.
Causes: Soilborne fungi that block water uptake.
Prevention:
Rotate crops—avoid planting tomatoes in the same spot for 2+ years.
Select disease-resistant varieties (labeled with “V” or “F” for resistance).
Remove and destroy infected plants.
By keeping an eye on early warning signs and using organic or chemical controls when necessary, you can minimize the damage from pests and diseases and enjoy a healthier tomato harvest.
Harvesting & Storage
Knowing when and how to harvest your tomatoes ensures the best flavor and quality. Proper storage techniques also help extend their freshness, whether you plan to eat them right away or preserve them for later use.
When to Harvest Tomatoes
Tomatoes should be picked at their peak ripeness for the best taste and texture. Here’s how to determine the right time:
Full Color: Harvest when the fruit is fully red (or the correct color for the variety), but still firm.
Slight Give: Gently squeeze the tomato—ripe ones should have a slight softness but not feel mushy.
Vine-Ripened vs. Early Picking:
Vine-ripened tomatoes offer the best flavor but can be more vulnerable to pests and cracking.
Pick early and ripen indoors if pests, extreme heat, or heavy rain threaten the fruit. Tomatoes will continue to ripen after picking.
If picking early, look for breaker stage tomatoes—those that have just started changing color from green to pink or red. These will ripen off the vine while still maintaining great flavor.
How to Harvest Tomatoes
Use pruning shears or scissors to snip the fruit off the vine, leaving a small portion of the stem attached.
Avoid pulling or twisting, as this can damage the plant.
Handle tomatoes gently to prevent bruising.
Storing Fresh Tomatoes
Proper storage keeps your tomatoes fresh and flavorful:
At Room Temperature: Store freshly picked tomatoes at room temperature (65-75°F), away from direct sunlight.
On the Counter: Place them stem-side down to prevent moisture loss.
Avoid Refrigeration: Cold temperatures dull the flavor and cause tomatoes to become mealy. Only refrigerate if they are fully ripe and you need to extend their shelf life.
Ripening Green Tomatoes:
Place green tomatoes in a paper bag with a banana or apple to speed up ripening.
Store them in a warm, dark place until they reach full color.
Long-Term Storage & Preservation
If you have an abundant harvest, consider these preservation methods:
Freezing: Chop tomatoes and freeze them in airtight bags for use in sauces and soups.
Canning: Preserve tomatoes in jars using a water bath canning method.
Drying: Slice and dehydrate tomatoes for sun-dried-style snacks.
Pickling: Make tomato relish or salsa to enjoy later.
With the right harvesting and storage methods, you can enjoy your homegrown tomatoes for weeks—or even months—after picking!
Conclusion
Growing tomatoes in Central Texas can be a rewarding and enjoyable experience. By selecting heat-tolerant varieties, preparing the soil properly, and following best practices for watering, fertilizing, and pest control, you can ensure a bountiful harvest of delicious homegrown tomatoes.
