📏
Spacing: 24-36 inches
📅
Days to maturity: 68-75 days from transplant

Growth Stages

1

Seedling

3-4 weeks

Small plants with 2-4 true leaves, delicate and light green

Provide 12-16 hours of bright light daily; keep soil moist but not waterlogged; maintain 65-75°F; thin seedlings if crowded

2

Transplant/Vegetative

2-4 weeks

Plants develop deeper root systems and 4-8 true leaves; stocky growth before hardening off

Gradually acclimate to outdoor conditions; fertilize weekly with diluted balanced fertilizer; pinch off lower leaves if they yellow

3

Flowering

3-4 weeks

Yellow flowers appear in clusters (racemes) along the main stem; plant becomes bushy and robust

Ensure consistent watering; support plant with stakes or cages early; provide balanced to slightly higher potassium fertilizer to encourage fruit set; maintain 65-80°F temperatures

4

Fruiting

4-6 weeks

Small green fruits develop behind flowers; fruits gradually enlarge and begin color transition from green to red

Prune suckers judiciously on determinate varieties to improve air circulation; maintain consistent watering to prevent cracks; reduce nitrogen to avoid excess foliage; apply mulch to regulate soil temperature

5

Harvest/Mature

4-6 weeks until frost

Fruits reach full red color and mature size (2-3 inches diameter); plant production slows in heat or stress

Harvest fruits at full red for best flavor; pick regularly to encourage continued production; monitor for end-of-season disease pressure; reduce watering slightly to concentrate sugars

Common Pests

  • Hand-pick early in morning; encourage parasitic wasps; use Bacillus thuringiensis (Bt) sprays for large infestations

  • Use reflective mulch; spray neem oil or insecticidal soap; introduce parasitic wasps or ladybugs

  • Spray with strong water stream; apply neem oil or insecticidal soap; introduce beneficial insects

  • Increase humidity; spray with neem oil or miticide; remove heavily infested leaves

  • Remove lower infected leaves; improve air circulation; avoid overhead watering; use fungicide if severe

Uses

🍳

Fresh eating and cooking

Culinary

Wildfire tomatoes are excellent eaten fresh in salads, sandwiches, or as snacks due to their balanced sweet-tart flavor. They also cook well in sauces, salsas, and cooked dishes. [source]

🍳

Canning and preservation

Culinary

Their determinate growth pattern and concentrated ripening make them ideal for home canning and sauce production. The acid content is suitable for water bath canning. [source]

💊

Nutritional and antioxidant benefits

Medicinal

Tomatoes are rich in lycopene, vitamin C, and potassium—compounds linked to heart health and disease prevention. Raw and cooked tomatoes both provide health benefits. [source]

🏠

Natural cleaning and dyeing

Household

Tomato juice can be used as a natural cleaner and deodorizer. Tomato-based liquids have been historically used in natural dyeing processes. [source]

🦋

Garden habitat and pollinator support

Wildlife

Tomato flowers attract bees and other pollinators, supporting beneficial insect populations in the garden ecosystem. Flowers also provide pollen resources. [source]

Harvest Tips

Pick fruits when they reach full red color for best flavor and sweetness. For Wildfire determinate varieties, most fruit typically ripens within a 2-4 week window. Harvest regularly to encourage continued production. To extend season, pick fruits at the breaker stage (when they first show color) and ripen indoors. If frost threatens, harvest all remaining fruits regardless of color—many will continue ripening off the vine.

Fun Facts

  • 🌱 The 'Wildfire' variety was developed for disease resistance and early ripening, making it a favorite among gardeners in cooler climates where the growing season is short.
  • 🌱 Tomatoes are technically fruits (berries), not vegetables—the 1893 U.S. Supreme Court case Nix v. Hedden ruled them vegetables for tariff purposes, but botanically they remain fruits.
  • 🌱 Wildfire's resistance to early blight (Alternaria) and fusarium wilt makes it one of the most disease-resistant determinate varieties available to home gardeners.
