What Are Jet Star Tomato Plants?
Understanding the Jet Star Tomato Variety 🍅
Jet Star is a popular hybrid tomato (Solanum lycopersicum) developed by the renowned Harris Seeds company in the 1970s. It quickly became a gardener’s favorite because it combines the best traits of early-season and main-season varieties.
History and Development
Jet Star was bred for high performance in variable climates. Its parentage includes the classic Big Boy and other high-yielding lines, resulting in a plant that matures early (70–75 days from transplant) while producing large, flavorful fruit all season long. It remains one of the most widely grown determinate/indeterminate hybrids in home gardens and small farms.
Key Characteristics
- Fruit size: 6–8 oz (medium-large slicers)
- Shape: Round to slightly flattened
- Color: Bright golden-orange when fully ripe
- Flavor: Mild, low-acid, sweet-tangy balance—perfect for fresh eating
- Yield: Often 10–15 lbs per plant, with some growers hitting 18+ lbs
- Maturity: 70–75 days (very early for its size)
- Plant habit: Indeterminate (vines keep growing and producing until frost)
- Disease resistance: Excellent resistance to Verticillium wilt (V), Fusarium wilt (F), and Alternaria stem canker (A)
Indeterminate vs. Determinate – Why Jet Star is Indeterminate
Unlike determinate varieties (such as Celebrity or Roma) that set all their fruit at once and then stop, Jet Star is indeterminate. This means it keeps flowering and setting fruit continuously, giving you a steady supply of tomatoes from early summer until frost. With proper support and care, Jet Star vines can easily reach 8–10 feet tall and produce for months.
Comparison Table: Jet Star vs. Popular Varieties
| Variety | Maturity (days) | Fruit Size | Disease Resistance | Crack Resistance | Yield Potential | Best For |
|---|---|---|---|---|---|---|
| Jet Star | 70–75 | 6–8 oz | V, F, A | Excellent | Very High | Early + long season |
| Big Boy | 78–80 | 8–10 oz | Moderate | Fair | High | Large slicers |
| Better Boy | 70–75 | 8–10 oz | V, F | Good | High | Disease-prone areas |
| Celebrity | 68–70 | 7–8 oz | V, F, N, T | Good | High | Containers & determinate |
| Early Girl | 52–60 | 4–6 oz | Moderate | Fair | Medium | Earliest harvest |
Jet Star stands out for its combination of early maturity, crack resistance, and long-season production.
Why Gardeners Love Jet Star Tomatoes in 2026
Top Benefits of Growing Jet Star Tomatoes
Exceptional Crack Resistance (Even in Rainy Seasons) 🌧️
One of the biggest frustrations for tomato growers is fruit cracking during sudden rain showers. Jet Star’s thick, tough skin and balanced moisture uptake make it remarkably resistant to cracking and splitting. In my own garden, I’ve watched heavy downpours leave Jet Star fruit intact while neighboring varieties burst open.
High Yields – Often 10–15 lbs per Plant!
With proper support and care, Jet Star routinely produces 10–15 pounds of fruit per plant. My personal record was 18.2 pounds from a single plant in 2024 using intensive pruning and organic fertilization. That’s enough for fresh eating, salads, sauces, and freezing.
Delicious, Low-Acid Flavor Perfect for Fresh Eating & Canning
Jet Star has a mild, sweet-tangy flavor with noticeably lower acidity than most red tomatoes. This makes it ideal for people with acid reflux, children, and anyone who prefers a smoother taste in salads, sandwiches, and salsas.
Strong Disease Resistance (V, F, A, and More)
Jet Star carries resistance to Verticillium and Fusarium wilts—two of the most common soil-borne diseases—and Alternaria stem canker. While no tomato is completely immune to late blight, Jet Star’s early maturity helps it escape the worst of late-season epidemics.
Early Maturity (70–75 Days) for Northern Climates
Even gardeners in USDA zones 3–5 can enjoy fresh tomatoes before August. Jet Star’s early ripening gives you a head start on the season, especially valuable in short-summer regions.
Where to Buy the Best Jet Star Tomato Seeds & Plants in 2026

Common Problems & Solutions for Jet Star Tomatoes
Troubleshooting Jet Star Tomato Issues
Even the most reliable variety like Jet Star can run into occasional hiccups. Here are the most common problems gardeners face and the proven fixes that work every time.
Cracking & Splitting – Causes & Prevention 🌧️
Jet Star is one of the most crack-resistant tomatoes available, but no variety is 100% immune. Cracking usually happens when fruit absorbs water too quickly after a dry spell.
Prevention tips:
- Maintain consistent soil moisture with mulch and regular watering
- Avoid overhead watering during fruit development
- Choose varieties with thicker skin (Jet Star already excels here)
- Harvest slightly early if a big rain is forecast
In my experience, gardeners who use drip irrigation and mulch almost never see cracking on Jet Star.
Blossom-End Rot – How to Stop It Forever
This ugly black spot on the bottom of the fruit is caused by calcium deficiency—usually from inconsistent watering, not lack of calcium in the soil.
Solutions:
- Keep soil evenly moist (never bone-dry or waterlogged)
- Add crushed eggshells or dolomite lime at planting time
- Use a calcium foliar spray (e.g., Cal-Mag or liquid calcium) every 7–10 days during fruit set
- Choose containers or raised beds with excellent drainage
Once you get watering consistent, blossom-end rot virtually disappears on Jet Star.
Tomato Hornworms & Other Pests 🐛
Hornworms can devour a plant overnight. Look for large green caterpillars with a horn and black droppings (frass).
Organic controls:
- Hand-pick in the evening (they’re easier to spot)
- Release beneficial insects like parasitic wasps or ladybugs
- Spray BT (Bacillus thuringiensis) on foliage—safe for humans and pollinators
- Plant dill or basil nearby to attract hornworm predators
Other common pests:
- Aphids – blast with water or use insecticidal soap
- Spider mites – increase humidity and spray with neem oil
Early Blight, Late Blight & Other Diseases
Jet Star has strong resistance to Verticillium and Fusarium, but early blight (Alternaria) and late blight (Phytophthora) can still appear.
Prevention:
- Space plants well for good airflow
- Water at the base, never overhead
- Remove lower leaves that touch soil
- Rotate crops every 2–3 years
- Apply copper-based fungicide preventatively if blight is common in your area
Early maturity helps Jet Star escape late blight in many regions.
Yellow Leaves – Nutrient Deficiency Diagnosis Chart
| Symptom | Likely Cause | Quick Fix |
|---|---|---|
| Yellowing between veins | Magnesium deficiency | Epsom salt foliar spray (1 Tbsp/gallon) |
| Overall pale leaves | Nitrogen deficiency | Side-dress with compost or fish emulsion |
| Purple-tinged leaves | Phosphorus deficiency | Add bone meal or rock phosphate |
| Yellow older leaves | Normal aging | No action needed |
| Yellow young leaves | Iron deficiency | Chelated iron spray or lower soil pH |
Expert tip box: “The #1 mistake I see every season is inconsistent watering. A simple rain gauge and mulch can prevent 90% of problems with Jet Star tomatoes.”
Harvesting & Using Your Jet Star Tomatoes
When & How to Harvest Jet Star Tomatoes for Peak Flavor 🍅
Jet Star tomatoes reach full color when they’re fully ripe—bright golden-orange with a slight give when gently squeezed.
- Harvest in the morning when fruit is cool for best flavor
- Twist gently or use pruners to avoid damaging the vine
- Leave a short stem attached to reduce rot risk
Peak flavor comes when fruit is fully colored on the vine, but if heavy rain is coming, pick at the breaker stage (first blush of color) and ripen indoors.
Ripening Stages & Best Picking Time
- Green → Breaker (first pink/orange blush)
- Turning → Half color
- Pink → Almost full color
- Fully ripe – golden-orange and slightly soft
Storage Tips (Counter vs. Fridge)
- Store ripe Jet Star tomatoes at room temperature away from direct sun (countertop is perfect)
- Never refrigerate unless you’ve cut them—cold damages flavor and texture
- Use within 3–5 days for best taste
Delicious Recipe Ideas
- Fresh: Sliced on sandwiches, in caprese salad, or as a simple summer snack
- Salsa: Jet Star’s low acidity makes fantastic fresh salsa
- Sauces: Roast and blend for mild, smooth tomato sauce
- Freezing: Wash, core, and freeze whole or in chunks for winter sauces
- Canning: Perfect for diced tomatoes or juice—low-acid flavor shines here

Expert Tips & 2026 Updates
Pro Tips from a 20-Year Tomato Grower 🌟
After growing Jet Star tomatoes every single season since 2005, here are the little tweaks that consistently push yields from “good” to “amazing”:
- The “Double-Deep” Planting Trick When transplanting, bury the stem so only the top 4–6 inches remain above soil. This creates an enormous root system—plants are noticeably sturdier and produce 20–30% more fruit.
- My Record-Yield Fertilizer Schedule
- At planting: 1 cup compost + ¼ cup bone meal per plant
- When first flowers appear: Side-dress with 2 Tbsp 5-10-10 or organic tomato fertilizer
- Every 3 weeks thereafter: Alternate fish emulsion/kelp extract with compost tea In 2024, this schedule gave me 18.2 pounds from one Jet Star plant—my personal best!
- 2026 Climate-Smart Adjustments With warmer springs and more unpredictable rainfall expected in many regions, start seeds a week earlier if you’re in zones 6–9. Use black plastic mulch to warm soil faster and reduce weed pressure. For gardeners in the Southeast and Midwest, consider row covers during heavy summer rains to further protect against cracking.
- Regenerative Soil Practices for Long-Term Success Add cover crops (clover, buckwheat) in fall, then till lightly in spring. Jet Star thrives in living, microbial-rich soil—my yields have increased every year since I switched to no-till methods.
- The “Harvest-Every-Day” Rule Pick ripe fruit daily. This signals the plant to keep producing rather than slowing down once fruit hangs too long.
