Celebrity Tomato in Zone 9B — Gulf Coast

Celebrity Tomato is a great choice for Gulf Coast gardeners looking for reliable flavor and performance. The fruits are classic tomato-y – juicy, slightly acidic, and perfect for slicing, sauces, or canning. Plus, its disease resistance helps it thrive in our humid conditions, giving you a satisfying harvest even with our long growing season.

Our high humidity and frequent afternoon storms definitely bring disease pressure, but don't let that scare you off. With a little planning and the right timing, you can grow delicious Celebrity Tomatoes. The 319-day growing season gives us plenty of opportunity to get it right.

To get a jump start on the season, start your Celebrity Tomato seeds indoors from late December through mid January. This gives them about 6 weeks to develop before transplanting. You'll need seed trays, a good seed-starting mix, and a warm, bright location.

A heat mat can help speed up germination, and a grow light ensures strong, healthy seedlings. Bottom watering is your friend here! It helps prevent damping-off, a common problem in our humid climate. As the weather starts warming up earlier than other regions, getting them started indoors early is key.

Transplant your Celebrity Tomato seedlings outdoors from mid February through mid March, after the danger of frost has passed. Before planting, harden them off by gradually exposing them to outdoor conditions for about a week. This prevents transplant shock.

Choose a sunny spot with well-drained soil and space the plants 24-36 inches apart. Keep an eye on the weather forecast during this time. We sometimes get unexpected cold snaps, so be ready to cover your young plants if needed.

Celebrity Tomatoes need consistent moisture, especially in our hot, humid Gulf Coast summers. Aim for about 1-2 inches of water per week, depending on rainfall. The "finger test" is your best friend – stick your finger about 2 inches into the soil. If it feels dry, it's time to water.

In the spring, you might get away with watering a couple of times a week, but once the heat kicks in, you'll likely need to water every other day, maybe even daily. Water at the base of the plant to avoid getting the foliage wet, which can encourage fungal diseases in our humid environment. Overwatering can cause yellowing leaves and root rot, while underwatering leads to blossom end rot and stunted growth.

A good layer of mulch, like pine straw or shredded leaves, helps retain moisture and suppress weeds. Just be sure to keep the mulch a few inches away from the stem to prevent rot.

Celebrity Tomatoes are considered determinate, but they can still get fairly bushy, so support is important. Cages or stakes both work well. I prefer medium-height cages because they're easy to install and provide good support without being too cumbersome.

Install your chosen support system at planting time. This prevents damaging the roots later. As the plant grows, gently guide the stems through the cage or tie them to the stake with soft twine.

Get ready to harvest your first Celebrity Tomatoes from late April through mid June. They're usually ready about 70 days after transplanting. Look for medium-large, red fruits that are firm but have a slight give when gently squeezed.

To harvest, simply twist the fruit gently until it separates from the vine. Regular harvesting encourages continued production. As the end of the season approaches and the first frost looms around mid- December, harvest any remaining green tomatoes and let them ripen indoors.

Here are three common problems you might encounter with Celebrity Tomatoes in the Gulf Coast:

Blossom Drop

• What it looks like: Flowers fall off the plant without setting fruit. Small fruit turns yellow and drops.
• What causes it: Temperature stress, especially when nighttime temperatures stay above 75°F or daytime temperatures exceed 95°F. Low humidity, excess nitrogen, or poor pollination can also contribute.
• How to fix/prevent it: Be patient – fruit set usually resumes when temperatures moderate. Provide afternoon shade during extreme heat. Keep plants well-watered, but avoid over-fertilizing with nitrogen. Try hand-pollination by gently shaking the flowers.

Hornworms

• What it looks like: Large sections of leaves stripped overnight. You might find large (up to 4 inches) green caterpillars with white diagonal stripes. Dark droppings on the leaves below are another telltale sign.
• What causes it: These are the larvae of hawk moths. The moths lay their eggs on tomato family plants, and the caterpillars feed voraciously.
• How to fix/prevent it: Handpick the hornworms (they don't bite). Bt (Bacillus thuringiensis) spray is effective and organic. If you see white cocoons on a hornworm, leave it! Those are parasitic wasp eggs that will kill the hornworm and produce more beneficial wasps.

Early Blight

• What it looks like: Brown spots with concentric rings (a target or bullseye pattern) appear on the lower leaves first, spreading upward. Leaves yellow and eventually drop.
• What causes it: This is 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 (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 slow the spread. Rotate crops yearly.

Gulf Coast Specific Challenges: Our hot, humid climate and frequent rainfall create the perfect environment for fungal diseases. Monitor your plants closely, provide good air circulation, and water at the base to minimize problems. Also be ready to deal with hornworms!

Companion planting can be a great way to improve your Celebrity Tomato crop. Basil is a classic companion because it repels pests like tomato hornworms and whiteflies. Plus, it's said to improve the flavor of the tomatoes. Carrots are also good neighbors, as they help loosen the soil and attract beneficial insects.

Parsley attracts hoverflies, which are beneficial predators that feed on aphids. French marigolds deter nematodes and other soil pests. Avoid planting brassicas (like cabbage, broccoli, and cauliflower) near your tomatoes, as they can stunt their growth. Fennel inhibits the growth of many plants, including tomatoes. Corn can also compete with tomatoes for nutrients and sunlight.
