Celebrity Tomato in Zone 3B — Midwest

Celebrity tomatoes are a fantastic choice for Midwest gardens. Their reliable flavor, disease resistance, and versatility in the kitchen make them a winner, even with our shorter growing season. Plus, there's nothing quite like the taste of a homegrown tomato sandwich on a warm summer evening.

Sure, we have our share of unpredictable spring weather and the occasional summer heat spell here in the Midwest. But with a little planning and attention to timing, you can absolutely enjoy a bountiful harvest of Celebrity tomatoes within our 118-day growing season.

Start your Celebrity tomato seeds indoors from mid-April through early May. This gives them about six weeks to get a head start before transplanting outdoors. Use seed trays or small pots filled with a good seed-starting mix.

Keep the soil consistently moist, and provide plenty of warmth and light. Bottom watering is a great way to keep the seedlings hydrated without overwatering the leaves. Remember, our spring weather can be a bit moderate-to-late, so starting indoors is crucial.

Transplant your Celebrity tomato seedlings outdoors from early to late June, after the danger of frost has passed. Before you plant them in the ground, harden them off for about a week. This means gradually exposing them to outdoor conditions for increasing periods each day.

When transplanting, space the plants 24-36 inches apart. This gives them plenty of room to grow and helps with air circulation. Keep an eye on the weather forecast around this time, as we can sometimes get late frosts.

Celebrity tomatoes need consistent moisture, especially here in the Midwest where we can experience summer heat spells alongside our typical wet-summer rainfall. Aim to keep the soil evenly moist, but not waterlogged. The "finger test" is your friend: stick your finger about two inches into the soil. If it feels dry, it's time to water.

Generally, you'll want to give your plants about 1-2 inches of water per week, depending on rainfall. Water at the base of the plants rather than overhead, as our moderate-to-humid conditions can increase the risk of fungal diseases. Wilting leaves can signal underwatering, while yellowing leaves may indicate overwatering.

A good layer of mulch around your tomato plants helps retain moisture and suppress weeds. Straw or shredded bark work well in our Midwest climate.

Celebrity tomatoes are a determinate variety, meaning they grow to a certain size and then stop. They're also sometimes called semi-determinate. But because they still produce a good amount of fruit, they benefit from support. Medium-height cages or sturdy stakes work best.

Install the support at planting time to avoid disturbing the roots later on. As the plant grows, gently guide the branches through the cage or tie them to the stake with soft twine. This prevents the plant from sprawling and keeps the fruit off the ground.

You can expect your first Celebrity tomato harvest from mid-August through mid-September. These are ready about 70 days from transplant. Look for medium-large, red fruit that is firm but has a slight give when gently squeezed. The excellent disease resistance of this variety often allows for a long harvest window.

To harvest, gently twist or cut the tomato from the vine, leaving a small piece of stem attached. Regular harvesting encourages continued production. As our first frost approaches in mid-September, harvest any remaining green tomatoes and bring them indoors to ripen. They'll continue to ripen on a windowsill.

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

Blossom Drop

• What it looks like: Flowers fall off without setting fruit, or small fruit yellows and drops. The plant looks healthy but produces no tomatoes.
• What causes it: Temperature stress. Nights above 75°F or days exceeding 95°F can prevent fruit set. Low humidity, excess nitrogen, or poor pollination can also contribute, particularly during our occasional summer heat spells.
• How to fix/prevent it: Be patient – fruit set usually resumes when temperatures moderate. Provide afternoon shade during extreme heat. Keep plants well-watered. Avoid excess nitrogen fertilizer. Try hand-pollination, especially during humid days.

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 and dark droppings on leaves.
• What causes it: These are the larvae of hawk moths. They lay their eggs on tomato family plants, and the caterpillars feed voraciously.
• How to fix/prevent it: Handpick them – they’re big and easy to spot (though they blend in well!). Bt (Bacillus thuringiensis) spray is effective and organic. If you see hornworms with white cocoons attached, leave them be – those are parasitic wasp eggs that will kill the hornworm and hatch 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: This fungal disease (Alternaria solani) thrives in warm, humid conditions and spreads via soil splash onto lower leaves. Our wet-summer rainfall can exacerbate this.
• How to fix/prevent it: Remove and destroy affected leaves (don't compost). Mulch well to prevent soil splash. Water at the base of the plant, not overhead. Improve air circulation through spacing and pruning. Copper fungicide can slow the spread. Rotate crops yearly.

Midwest Specific Challenges: The moderate-to-hot heat and moderate-to-humid humidity we experience in the Midwest, combined with our wet-summer rainfall, can create ideal conditions for fungal diseases like early blight. Vigilance and preventative measures are key to a successful harvest.

Companion planting can give your Celebrity tomatoes a boost. Basil is a great companion because it repels tomato hornworms and other pests, plus it improves the flavor of the tomatoes. Carrots and parsley also make good neighbors, attracting beneficial insects that prey on tomato pests. French marigolds deter nematodes and other soil pests.

Avoid planting tomatoes near brassicas (like cabbage and broccoli) as they can stunt tomato growth. Fennel inhibits the growth of many plants, including tomatoes. Corn can also be a poor companion, as it attracts some of the same pests.
