Growing Conditions

☀️
Sun: Full sun, 6-8 hours daily minimum; 8+ hours optimal for best flavor
💧
Water: Consistent moisture; water deeply 1-2 inches per week. Keep soil evenly moist but not waterlogged. Water at soil level in early morning to reduce disease. Reduce watering slightly as fruit ripens to concentrate sugars.
📏
Spacing: 24-36 inches between plants; 36-48 inches between rows inches
📅
Days to maturity: 65-75 days from transplant to first ripe fruit
🌱
Planting depth: 0.25 inches for seeds; plant transplants so soil reaches first true leaves (stem will root)

Soil

Type: Well-draining loamy soil rich in organic matter
pH: 6.0-6.8
Amendments:
Compost or aged manure Balanced fertilizer (5-10-10) Calcium (lime or gypsum) to prevent blossom-end rot Mulch layer (2-3 inches)

Growth Stages

1

Seedling

2-3 weeks until first true leaves appear

Tiny plants with 2 cotyledons and emerging true leaves; delicate and pale green

Keep soil moist but not soggy. Provide 12-16 hours of bright light daily. Maintain 65-75°F temperature. Use grow lights 2-3 inches above seedlings.

2

Vegetative Growth

3-4 weeks in containers before field transplanting

Rapid stem and leaf development; plant becomes bushy with 6-12 leaves; main stem thickens

Harden off for 7-10 days before transplanting outdoors. Prune suckers on indeterminate varieties (Transit is determinate, minimal pruning needed). Begin light fertilizing at 2-week intervals.

3

Flowering

2-3 weeks as flowers continue to form

Yellow flowers appear in clusters (trusses); plant reaches mature height; buds set along stem

Maintain consistent watering to prevent blossom-end rot. Fertilize with lower nitrogen (higher phosphorus/potassium). Ensure adequate calcium. Good pollination critical—maintain 60-75°F nights for fruit set.

4

Fruit Development & Ripening

4-6 weeks from small fruit to mature red tomatoes

Green fruits mature to full size; gradually ripen from green to red over 20-30 days per truss

Uniform ripening is Transit's strength; fruits ripen simultaneously across plant. Reduce nitrogen fertilizer. Maintain consistent watering; drought stress cracks fruit. Remove excess foliage only if needed for light penetration to fruit.

5

Harvest

2-4 weeks of active harvesting

Fully red, firm fruits ready for picking; plant may continue producing secondary flushes

Pick tomatoes when completely red for best flavor. Handle gently to avoid bruising. Continue watering and light fertilizing for extended harvest. Transit's determinate nature means concentrated ripening—most fruit ready within 2-3 week window.

Common Pests

  • Hand-pick or use Bacillus thuringiensis (Bt). Check undersides of leaves. Beneficial wasps provide natural control.

  • Spray with neem oil or insecticidal soap. Use yellow sticky traps. Remove infested leaves.

  • Increase humidity and water plants at soil level. Spray with water to dislodge. Use miticide if severe.

  • Remove lower infected leaves. Mulch to prevent soil splash. Apply copper fungicide. Improve air circulation.

  • Remove infected plant material immediately. Apply chlorothalonil or copper fungicide. Ensure good drainage and air flow.

  • Remove affected leaves. Avoid overhead watering. Apply fungicide if needed. Rotate crops.

  • Spray with water or insecticidal soap. Introduce ladybugs. Use neem oil for heavy infestations.

Uses

🍳

Canning & Preserving

Culinary

Transit's determinate ripening pattern and uniform fruit size make it ideal for home canning, sauce-making, and preserves. The fruits have good acidity and solid flesh content. [source]

🍳

Fresh Eating & Salads

Culinary

Medium-sized fruits with balanced sweet-tart flavor are excellent sliced fresh, in salads, or on sandwiches. [source]

💊

Lycopene & Heart Health

Medicinal

Ripe red tomatoes contain high levels of lycopene, a powerful antioxidant associated with reduced risk of heart disease and certain cancers. [source]

🏠

Tomato Sauce & Paste

Household

Transit's meaty texture and concentrated flavor profile make it excellent for reducing into tomato paste, marinara sauce, and other concentrated tomato products. [source]

🦋

Pollinator Support

Wildlife

Tomato flowers attract bees and other pollinators to the garden, supporting broader ecosystem health and fruit set. [source]

Harvest Tips

Transit is a determinate variety, meaning it concentrates fruit ripening into a 2-3 week window—ideal for preserving and canning. Pick tomatoes when fully red for maximum flavor and lycopene content. Twist gently or cut with pruners to avoid damaging vine. Morning harvests preserve juiciness. For longer shelf-life, pick at 'breaker stage' (first blush of color) and ripen at room temperature. Transit produces heavily but stops setting fruit in extreme heat (above 90°F) or cold (below 60°F nights).

Fun Facts

  • 🌱 Transit was developed in the 1950s-60s for mechanical harvesting in commercial agriculture, making it one of the first 'purpose-bred' tomato varieties. Its simultaneous ripening and compact determinate form revolutionized commercial tomato production.
  • 🌱 The name 'Transit' reflects its breeding goal: to produce a tomato that could be harvested all at once and 'transit' efficiently to market, rather than requiring multiple pickings over weeks.
  • 🌱 Transit tomatoes contain about 20-30 mg of vitamin C per 100g and are an excellent source of potassium, fiber, and the antioxidant quercetin in addition to lycopene.
