Celebrity Tomato in Zone 3A — Great Plains

The Celebrity Tomato is a winner for Plains gardeners. Its reliable yields, delicious flavor, and good disease resistance make it a standout, even with our extreme weather. You'll enjoy fresh, juicy tomatoes perfect for slicing, salads, or canning – a real treat after a long winter.

Our short growing season and variable weather demand careful planning. But don't worry, with a little attention to timing, you can absolutely grow Celebrity Tomatoes successfully. The 108-day growing season is manageable, and this variety's disease resistance is a big plus in our climate.

Starting Celebrity Tomato seeds indoors gives you a crucial head start in our short season. You have about a 3-week window, from mid-April through mid-May, to get those seeds going – roughly 6 weeks before you plan to transplant them outside. Use seed trays or small pots filled with a good seed-starting mix.

Keep the trays warm (around 70-75°F) and provide plenty of light. A heat mat can help with germination, and grow lights are almost essential to prevent leggy seedlings. Water gently from the bottom to avoid damping off. Our spring weather is variable, so indoor starting is the way to go.

Transplant your Celebrity Tomato seedlings outdoors in early to mid-June, after the risk of frost has passed. Before transplanting, harden them off by gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade, increasing the time and sunlight each day.

Plant your seedlings 24-36 inches apart in a sunny spot with well-drained soil. The Plains can still experience some chilly nights even in June, so keep an eye on the forecast and be ready to cover your plants if needed.

Consistent watering is key for Celebrity Tomatoes, especially in our Plains climate. They need a good amount of water to produce those juicy fruits, and they're not drought-tolerant, so you'll need to stay on top of it. During the heat of summer, aim for about 1-2 inches of water per week, depending on rainfall.

Check the soil moisture by sticking your finger about 2 inches deep. If it feels dry, it's time to water. Water deeply at the base of the plant to encourage strong root growth and reduce the risk of foliar diseases in our low-to-moderate humidity. Avoid overhead watering, especially in the evening.

Underwatering can cause blossom end rot and stunted growth. Overwatering can lead to root rot. Symptoms of underwatering include wilting and dry, cracked soil. Overwatered plants may have yellowing leaves and the soil will be consistently soggy. Mulching around your plants with straw or wood chips helps retain moisture and regulate soil temperature, which is especially helpful with our extreme temperature swings.

Celebrity Tomatoes are considered determinate, but they can still get fairly large, so providing support is important. A sturdy cage or stake works well to keep the plant upright and prevent the fruit from touching the ground. Medium-height cages are usually sufficient.

Install the support at planting time to avoid disturbing the roots later. As the plant grows, gently guide the stems through the cage or tie them to the stake with soft twine. Wind protection is essential in the Plains, so choose a sheltered spot or use a windbreak to prevent damage to your plants and support structures.

You can expect your first Celebrity Tomato harvest from mid-August through early September in our region. The fruits are ready to pick when they are a deep red color, firm to the touch, but with a slight give when gently squeezed. They should be medium-large in size.

Gently twist or cut the tomato from the vine, taking care not to damage the plant. Regular harvesting encourages continued production. As the first frost approaches in early September, harvest any remaining green tomatoes and bring them indoors to ripen. They'll ripen best in a single layer, not touching each other.

Even with its good disease resistance, the Celebrity Tomato can still face some challenges in the Plains. Here are three common problems and how to address them:

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 is the main culprit. Our hot days and fluctuating temperatures can prevent fruit set. Low humidity, excess nitrogen, or poor pollination can also contribute.
• How to fix/prevent it: Be patient – fruit set should resume when temperatures moderate. Provide afternoon shade during extreme heat. Keep plants well-watered but avoid over-fertilizing with nitrogen. You can also try hand-pollinating the flowers.

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: These are the larvae of hawk moths. They can defoliate your plants quickly.
• How to fix/prevent it: Handpicking is effective – they’re easy to spot. Bt (Bacillus thuringiensis) spray is a safe and organic option. If you see hornworms with white cocoons on their backs, leave them alone – those are parasitic wasp eggs that will kill the hornworm and release 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 thrives in warm conditions. It spreads via soil splash onto lower leaves.
• How to fix/prevent it: Remove and destroy affected leaves. Mulch 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 your crops each year.

Great Plains Specific Challenges: The hot, dry summers in the Plains can stress tomato plants, making them more susceptible to blossom drop and other problems. Our variable rainfall means you need to monitor soil moisture carefully. The wind can also damage plants, so provide adequate support and wind protection.

Companion planting can help your Celebrity Tomatoes thrive in the Plains. 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 repel nematodes and other soil pests.

Avoid planting tomatoes near brassicas (cabbage, broccoli, cauliflower) as they can stunt tomato growth. Fennel inhibits the growth of many plants, including tomatoes. Corn can shade tomatoes and compete for nutrients and water, which isn't ideal in our already challenging climate.
