Celebrity Tomato in Zone 3B — Great Plains

Celebrity Tomato is a reliable choice for us Plains gardeners. Its great taste and versatility in the kitchen make it a winner, and you'll be proud to harvest your own slicing tomatoes despite our challenging climate. Plus, its disease resistance is a real bonus, especially when our weather throws curveballs.

Our short growing season and extreme weather can make tomato growing feel like a gamble. But Celebrity's relatively short maturity time of 70 days gives us a good shot at a successful harvest. Proper timing and a little extra care will get you there.

Start your Celebrity Tomato seeds indoors from mid-April through early May. That gives you about 6 weeks to get strong seedlings ready for transplanting after the last frost. Use seed trays or small pots filled with a good seed-starting mix.

Keep the soil consistently moist, and provide bottom heat with a heat mat to speed germination. Once seedlings emerge, they'll need plenty of light. A grow light is ideal, especially given our variable spring weather. Bottom watering helps prevent damping off disease and keeps the leaves dry.

Remember, spring in the Plains can be fickle. Be ready to adjust your setup if we get an unexpected cold snap. Keeping an eye on the forecast is key.

Transplant your Celebrity Tomato seedlings outdoors from early to late June, after all danger of frost has passed. Before planting, harden them off by gradually exposing them to outdoor conditions for about a week. This helps them adjust to the sun and wind, which can be brutal on tender seedlings.

Space your plants 24-36 inches apart to allow for good air circulation. When transplanting, dig a hole deep enough to bury the stem up to the first set of leaves – this encourages more root growth. Be sure to protect your young plants from unexpected late frosts; row covers or even buckets can provide temporary protection.

Our Plains weather can be unpredictable even in June. Keep an eye out for hail and strong winds, and be ready to provide temporary shelter if needed.

Celebrity Tomatoes need consistent moisture to thrive, especially in our Plains climate. They aren't very drought-tolerant, so regular watering is essential for good fruit production. During the hottest part of the summer, you might need to water deeply every other day.

Use the "finger test" – stick your finger into the soil about 2 inches deep. If it feels dry, it's time to water. Aim for about 1-2 inches of water per week, depending on rainfall. Water at the base of the plant to avoid wetting the leaves. Overhead watering can increase the risk of fungal diseases, especially with our occasional humidity spikes.

Signs of underwatering include wilting leaves and dry soil. Overwatering can lead to yellowing leaves and root rot. Mulching around your tomato plants with straw or wood chips helps retain moisture and suppress weeds, which is especially helpful given our variable rainfall.

Celebrity Tomato is a determinate variety, meaning it grows to a set size and produces most of its fruit at once. While not as tall as indeterminate types, they still benefit from support. Cages or sturdy stakes work well to keep the plants upright and the fruit off the ground.

Install your chosen support at planting time to avoid damaging the roots later. Gently tie the plant to the stake as it grows, or guide the branches inside the cage. This prevents them from sprawling and keeps the fruit clean.

Given our windy conditions on the Plains, make sure your supports are well-anchored. A strong gust can easily topple an unsupported tomato plant. Wind protection is essential.

You can expect your first Celebrity Tomato harvest from mid-August through mid-September, about 70 days after transplanting. The fruits are ready when they are a deep red color, firm to the touch, and have a slight give when gently squeezed.

To harvest, grasp the fruit gently and twist or cut it from the vine, leaving a small piece of stem attached. Regular harvesting encourages the plant to continue producing. Check your plants every few days for ripe tomatoes.

As our first frost approaches in mid-September, keep a close eye on the forecast. If frost is predicted, harvest any remaining mature green tomatoes. They will ripen indoors in a paper bag or on a windowsill.

Even with good care, Celebrity Tomatoes can run into problems. Here are a few common issues we see in the Great Plains:

Blossom Drop

• What it looks like: Flowers fall off without setting fruit. Small fruit yellows and drops. The plant looks healthy but produces no fruit.
• What causes it: Temperature stress. Our extreme temperature swings can cause blossom drop, especially when nights stay too warm. Low humidity and 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. Avoid excess nitrogen. Try hand-pollination, especially when it's not windy.

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 plants quickly.
• How to fix/prevent it: Handpick them. They're big, so easy to spot. Bt (Bacillus thuringiensis) spray is effective and organic. If you see white cocoons on a hornworm, leave it — those are parasitic wasp eggs.

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: A fungal disease (Alternaria solani) that thrives in warm, humid 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, not overhead. Improve air circulation through spacing and pruning. Copper fungicide slows spread. Rotate crops yearly.

Great Plains Specific Challenges: Our hot summers, low-to-moderate humidity, and variable rainfall can all stress Celebrity Tomatoes. Consistent watering is crucial to prevent blossom drop and keep plants healthy. Mulching helps retain moisture and prevent soil splash, reducing the risk of early blight. Wind protection is also key to prevent damage and stress.

Companion planting can help your Celebrity Tomatoes thrive. Basil is a classic companion, improving flavor and repelling pests. Carrots and parsley attract beneficial insects that prey on tomato pests. French marigolds deter nematodes and other soil pests.

Avoid planting brassicas (cabbage, broccoli, cauliflower) near tomatoes, as they can stunt tomato growth. Fennel inhibits the growth of many plants, including tomatoes. Corn can block sunlight and compete for nutrients, which isn't ideal in our short growing season.
