Celebrity Tomato in Zone 4B — Great Plains

Celebrity Tomato is a solid choice for us Plains gardeners. It's a reliable producer of flavorful, medium-sized tomatoes that are great for slicing, salads, and sauces. Plus, its good disease resistance means it can handle our variable weather without too much fuss, and that's always a win in our book.

We all know gardening in the Great Plains comes with its share of challenges, from extreme temperature swings to the occasional hail. But with a little planning and attention to timing, you can definitely enjoy a successful Celebrity Tomato harvest within our roughly 149-day growing season.

Starting Celebrity Tomato seeds indoors is the way to go for us in the Plains. Get those seeds going from late March through late April, about six weeks before you plan to put them outside. This gives them a head start before our unpredictable spring weather hits.

You'll need some seed trays, a good seed-starting mix, and a warm spot, ideally around 70-75°F. A heat mat can really help speed up germination. Once the seedlings emerge, they'll need plenty of light. A grow light is best, especially with our variable spring sunshine, but a sunny south-facing window can work in a pinch. Don't forget to water from the bottom to encourage strong root growth and prevent damping off.

Transplant time for Celebrity Tomatoes is typically mid May through mid June, after the danger of frost has passed. Before you plant them out, you'll want to harden them off. This means gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade and increase the time and sun exposure each day.

When transplanting, space your Celebrity Tomato plants about 24-36 inches apart. Watch the weather forecast closely. A late frost or a sudden hailstorm can set your plants back, so be ready to cover them if needed.

Celebrity Tomatoes need consistent moisture to produce those juicy fruits, and keeping them watered right is key in our Plains climate. While they are not drought-tolerant, good disease resistance allows for some forgiveness in beginner gardening.

During the heat of summer, especially when we're facing drought conditions, you might need to water deeply every few days. Stick your finger about two inches into the soil – 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 getting the leaves wet, which can lead to disease, even with Celebrity's resistance. Low-to-moderate humidity means we don't need to worry as much about foliar diseases as other regions.

If the leaves are wilting and the soil is dry, your plant is underwatered. If the leaves are yellowing and the soil is soggy, you might be overwatering. A good layer of mulch around the base of the plant will help retain moisture and keep the soil cool, which is especially important during those hot Plains summers.

Celebrity Tomato plants are determinate, meaning they grow to a certain size and then stop. But they still need support to keep those heavy fruits off the ground. Since it's a semi-determinate variety, medium-height cages work great.

Install your cages or stakes at planting time to avoid disturbing the roots later. As the plant grows, gently guide the branches inside the cage to keep them contained. With our Plains winds, sturdy support is essential to prevent your plants from toppling over.

You can expect your first Celebrity Tomato harvest from late July through mid September, about 70 days after transplanting. The tomatoes are ready when they're a deep red color, firm to the touch, but with a slight give when you gently squeeze them.

To harvest, simply twist the tomato until the stem snaps off. Be careful not to damage the plant while you're picking. Keep harvesting regularly to encourage the plant to produce more fruit. As our first frost approaches in early October, harvest any remaining green tomatoes and bring them inside to ripen. They'll still taste great, even if they're not quite as perfect as the vine-ripened ones.

Even with Celebrity Tomato's good disease resistance, we can still run into problems in the Great Plains. Here are three common ones to watch out for:

Blossom Drop

• What it looks like: Flowers fall off without setting fruit. Small fruit yellows and drops. The plant looks healthy otherwise but produces no tomatoes.
• What causes it: Temperature stress is the main culprit. Our extreme temperature swings, especially hot days followed by warm nights, can prevent fruit set. Low humidity, excess nitrogen, or poor pollination can also contribute.
• How to fix/prevent it: Be patient – fruit set will usually 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 by gently shaking the plant.

Hornworms

• What it looks like: Large sections of leaves are stripped overnight. You might also see large (up to 4 inches) green caterpillars with white diagonal stripes and dark droppings on the leaves below.
• 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: Handpicking is the easiest solution – they're big, so they're easy to spot (though they blend in well!). Bt (Bacillus thuringiensis) spray is also effective and organic. If you see hornworms with white cocoons on their backs, leave them alone – 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, then spread upward. The leaves eventually yellow and drop off.
• What causes it: This is a fungal disease (Alternaria solani) that thrives in warm conditions. It spreads via soil splash onto the lower leaves.
• How to fix/prevent it: Remove and destroy any affected leaves (don't compost them!). Mulch around the base of the plant to prevent soil splash. Water at the base, not overhead. Improve air circulation by spacing plants properly and pruning. Copper fungicide can help slow the spread. Rotate your crops each year to prevent the fungus from building up in the soil.

Great Plains Specific Challenges: Our hot summers and variable rainfall can stress Celebrity Tomato plants, making them more susceptible to these problems. Consistent watering and good air circulation are key to keeping your plants healthy and productive.

Companion planting can really help your Celebrity Tomatoes thrive here in the Plains. Basil is a great choice because it repels tomato hornworms and other pests, plus it improves the flavor of the tomatoes. Carrots can help loosen the soil and attract beneficial insects. Parsley also attracts beneficial insects and can improve the overall health of your tomato plants. French marigolds are known to repel 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.
