Celebrity Tomato in Zone 9A — Florida

Celebrity tomatoes are a fantastic choice for Florida gardeners. Their reliable flavor, disease resistance, and versatility in the kitchen make them a rewarding crop. Plus, they consistently produce a good yield, giving you plenty of delicious tomatoes to enjoy.

Florida's gardening calendar is different, and we face unique challenges like high humidity and nematodes. But with careful timing, you can successfully grow Celebrity tomatoes during our extended 327-day growing season. We plant in fall and harvest in winter. Summer is the slow season.

To get a head start on your Celebrity tomatoes, start your seeds indoors from late December through mid January. This gives them about six weeks to develop before transplanting. A reversed spring character means we start early to avoid the worst of the summer heat.

Use seed trays or small pots filled with a good seed-starting mix. Keep the soil consistently moist (but not soggy) by watering from the bottom. Provide warmth with a heat mat and plenty of light with grow lights.

Transplant your Celebrity tomato seedlings outdoors from mid February through mid March, after 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 sun and wind.

Plant them 24-36 inches apart in a sunny spot with well-drained soil. Amend our sandy Florida soil with plenty of compost to improve water retention and fertility.

Celebrity tomatoes need consistent moisture to thrive, especially in Florida's hot climate. Aim for about 1-2 inches of water per week, depending on rainfall. Use the "finger test" – if the soil feels dry about 2 inches below the surface, it's time to water.

During the hotter, drier periods of spring, you'll likely need to water more frequently. In the wet summer, you might need to water less, but keep an eye on the soil moisture. Water at the base of the plant to avoid wetting the leaves, which can encourage fungal diseases in our humid environment.

Signs of underwatering include wilting leaves and dry soil. Overwatering can lead to yellowing leaves and root rot. A good layer of mulch around your plants helps retain moisture and suppress weeds.

Celebrity tomatoes are determinate, meaning they grow to a certain size and then stop. However, they still need support to keep the fruit off the ground. Because they are semi-determinate, medium-height cages work perfectly to support the plant.

Install the cage or stake at planting time to avoid disturbing the roots later. As the plant grows, gently guide the stems and branches inside the cage.

You can expect your first Celebrity tomato harvest from late April through mid June, about 70 days after transplanting. The tomatoes are ready to pick when they are medium-large, fully red, and slightly firm to the touch.

Gently twist the tomato from the vine, taking care not to damage the plant. Regular harvesting encourages continued production. Even though we have a long growing season, keep an eye on the forecast as late December approaches. If a frost is predicted, harvest any remaining green tomatoes and let them ripen indoors.

Here are some common problems you might encounter with Celebrity tomatoes in Florida:

Blossom Drop

• What it looks like: Flowers fall off without setting fruit. Small fruit yellows and drops. Plant looks healthy but produces no fruit.
• What causes it: Temperature stress, especially when nights stay above 75°F or days exceed 95°F. Can also be caused by low humidity, excess nitrogen, or poor pollination.
• How to fix/prevent it: Be patient – fruit set resumes when temperatures moderate. Provide afternoon shade during extreme heat. Keep plants well-watered. Avoid excess nitrogen. Try hand-pollination.

Hornworms

• What it looks like: Large sections of leaves stripped overnight. Large (up to 4 inches) green caterpillars with white diagonal stripes. Dark droppings on leaves below.
• What causes it: Larvae of hawk moths. Eggs laid on tomato family plants. Caterpillars feed voraciously and can defoliate plants quickly.
• How to fix/prevent it: Handpick (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 it and produce more beneficial wasps.

Early Blight

• What it looks like: Brown spots with concentric rings (target or bullseye pattern) on lower leaves first, spreading upward. Leaves yellow and drop.
• What causes it: Fungal disease (Alternaria solani) that thrives in warm, humid conditions. Spreads via soil splash onto lower leaves.
• How to fix/prevent it: Remove and destroy affected leaves (don't compost). Mulch to prevent soil splash. Water at the base, not overhead. Improve air circulation through spacing and pruning. Copper fungicide slows spread. Rotate crops yearly.

Florida Specific Challenges: The combination of hot heat, very-high humidity, and our wet-summer rainfall creates a perfect environment for fungal diseases like early blight. Nematodes in the soil can also be a problem. Choose nematode-resistant varieties and practice good soil health to minimize these issues.

Companion planting can help your Celebrity tomatoes thrive. Basil is a great companion because it repels tomato hornworms and other pests. Carrots improve the soil around tomatoes and deter nematodes. Parsley attracts beneficial insects that prey on tomato pests. French marigolds also repel nematodes and other soil pests.

Avoid planting brassicas (like cabbage and broccoli) near tomatoes because they can stunt tomato growth. Fennel inhibits the growth of many plants, including tomatoes. Corn can attract tomato pests and diseases.
