Celebrity Tomato in Zone 7A — Texas

Celebrity tomatoes are a Texas gardener's dream – reliable, delicious, and perfect for everything from fresh salads to homemade sauce. Their balanced flavor and medium size make them incredibly versatile, and there's nothing quite like the satisfaction of harvesting your own homegrown tomatoes, especially with our long growing season.

We know Texas weather can be unpredictable, throwing everything from late freezes to scorching heat at us. But with a little planning and attention to timing, you can absolutely enjoy a bountiful Celebrity tomato harvest. Our long 245-day growing season gives you a great head start.

Starting your Celebrity tomato seeds indoors gives them a head start against the Texas heat. Aim to start your seeds indoors from early February through early March, about six weeks before you plan to transplant them outside. You'll need seed trays, a good seed-starting mix, and a warm, bright location.

A heat mat can help speed up germination. Once the seedlings emerge, provide plenty of light – a grow light works best. Remember to water from the bottom to encourage strong root growth and prevent damping-off. With our early spring character, you want them ready to go as soon as the weather cooperates.

Transplant your Celebrity tomato seedlings outdoors from late March through late April, once the danger of frost has passed. Before transplanting, harden off your seedlings by gradually exposing them to outdoor conditions for about a week. This helps them adjust to the Texas sun and wind.

Choose a sunny spot with well-drained soil, and space the plants 24-36 inches apart. Keep an eye on the forecast for any late cold snaps. Even a light frost can damage young tomato plants. Be ready to cover them if needed.

Celebrity tomatoes need consistent moisture, especially in the Texas heat. They aren't drought-tolerant, so regular watering is crucial for good fruit production. A good rule of thumb is to water deeply once or twice a week, providing about 1-2 inches of water each time, depending on rainfall.

Use the "finger test" to check soil moisture: stick your finger into the soil about 2 inches deep. If it feels dry, it's time to water. Water at the base of the plant to avoid wetting the foliage, which can encourage disease, especially with our variable humidity. During the hottest parts of the summer, you may need to water more frequently.

Underwatering can cause blossom end rot, while overwatering can lead to root rot. Signs of underwatering include wilting leaves and dry soil. Overwatering can cause yellowing leaves and soggy soil. Mulching around your tomato plants with straw or wood chips helps retain moisture and suppress weeds.

Celebrity tomatoes are considered determinate, but they can still get fairly large, so providing support is important. Cages or stakes both work well. Because they are semi-determinate, medium-height cages are usually sufficient.

Install your chosen support at planting time to avoid disturbing the roots later. As the plant grows, gently guide the stems inside the cage or tie them to the stake. This will help keep the fruit off the ground and prevent the plant from collapsing under its own weight.

You can expect your first Celebrity tomato harvest from early June through late July, about 70 days after transplanting. The tomatoes are ready to pick when they are a deep red color, firm but with a slight give when gently squeezed. They have excellent disease resistance so you should get a good crop.

Gently twist or cut the tomatoes from the vine, being careful not to damage the plant. Regular harvesting encourages continued production. As our first frost approaches in mid- November, harvest any remaining green tomatoes and bring them indoors to ripen. They'll ripen best in a single layer, away from direct sunlight.

Here are three common problems you might encounter with Celebrity tomatoes in Texas:

• Blossom Drop
• What it looks like: Flowers fall off the plant without setting fruit. Small fruits may yellow and drop off too.
• What causes it: Temperature stress is the main culprit. Nights above 75°F or days exceeding 95°F prevent fruit set. Low humidity, excess nitrogen, and poor pollination can also contribute.
• How to fix/prevent it: Be patient – fruit set will resume when temperatures moderate. Provide afternoon shade during the hottest part of the day. Keep plants well-watered, but avoid over-fertilizing with nitrogen. Try hand-pollinating blossoms during periods of low bee activity.
• Hornworms
• What it looks like: Large sections of leaves stripped overnight. Look for large (up to 4 inches) green caterpillars with white diagonal stripes, and dark droppings on the leaves below.
• What causes it: These are the larvae of hawk moths, which lay their eggs on tomato plants. The caterpillars feed voraciously.
• How to fix/prevent it: Handpick the hornworms and drop them in a bucket of soapy water. Bt (Bacillus thuringiensis) spray is an effective organic control. If you see hornworms with white cocoons on their backs, leave them alone – those are parasitic wasp eggs that will kill the hornworm.
• Early Blight
• What it looks like: Brown spots with concentric rings (a "target" or "bullseye" pattern) appear on the lower leaves first, spreading upward. The leaves will eventually yellow and drop off.
• What causes it: A fungal disease (Alternaria solani) that thrives in warm, humid conditions. It spreads via soil splash onto the lower leaves.
• How to fix/prevent it: Remove and destroy affected leaves immediately (don't compost them). Mulch around the plants to prevent soil splash. Water at the base of the plant, not overhead. Improve air circulation by spacing plants properly and pruning. Copper fungicide can help slow the spread of the disease. Rotate your tomato crops yearly.

Texas Specific Challenges: The hot-to-extreme heat, variable humidity, and unpredictable rainfall in Texas can exacerbate these problems. The key is to provide consistent moisture, good air circulation, and protection from the harshest sun. Monitor your plants closely and take action quickly when you spot any signs of trouble.

Companion planting can give your Celebrity tomatoes a boost in the Texas garden. Basil is a great companion because it repels tomato hornworms and whiteflies, plus it improves the flavor of the tomatoes. Carrots help improve the soil around the tomato plants, and parsley attracts beneficial insects. French marigolds deter nematodes and other soil pests.

Avoid planting brassicas (like cabbage, broccoli, and kale) near your tomatoes, as they can stunt the tomato plants' growth. Fennel inhibits the growth of many plants, including tomatoes. Corn competes with tomatoes for nutrients and can also attract pests.
