How Long Does It Take to Grow Tomatoes?

Quick Answer

Tomatoes take 60–85 days from transplanting outdoors to the first ripe fruit, depending on the variety. If starting from seed indoors, add 6–8 weeks, making the total time from seed to harvest about 3–4.5 months.

Timeline by Variety

Early-Season Varieties (50–65 days from transplant)

• Early Girl: 50–62 days
• Cherry tomatoes (Sungold, Sweet 100): 55–65 days
• Juliet: 60 days

Mid-Season Varieties (65–80 days)

• Better Boy: 70–75 days
• Celebrity: 70 days
• Roma: 75–80 days
• San Marzano: 78–80 days

Late-Season Varieties (80–95+ days)

• Brandywine: 80–90 days
• Beefsteak: 85–90 days
• Cherokee Purple: 80–90 days

Full Growth Timeline

• Weeks 1–2 (indoors): Seeds germinate in 5–10 days
• Weeks 3–6 (indoors): Seedlings develop true leaves
• Weeks 6–8 (indoors): Harden off seedlings before transplanting
• Transplant outdoors: after last frost, when soil is 60°F+
• Weeks 1–4 (outdoors): Plants establish roots and grow vigorously
• Weeks 4–8: Flowering begins
• Weeks 8–12: Green fruit develops
• Weeks 10–14: First ripe tomatoes

Factors That Affect Growth Time

Variety selection has the biggest impact. Cherry tomatoes ripen weeks earlier than large beefsteak varieties.

Temperature is critical. Tomatoes grow best between 65–85°F. Below 55°F, growth stalls. Above 90°F, flowers drop without setting fruit.

Sunlight — tomatoes need 6–8 hours of direct sun daily. Less sun means slower growth and less fruit.

Soil quality and consistent watering affect growth speed. Rich, well-draining soil with consistent moisture (not waterlogged) produces the best results.

Determinate vs. indeterminate — determinate varieties produce all their fruit at once and are often earlier. Indeterminate varieties keep growing and producing until frost.

Tips for a Better Harvest

• Start seeds indoors 6–8 weeks before last frost for the earliest harvest
• Harden off seedlings by gradually exposing them to outdoor conditions over 7–10 days
• Plant deep — bury 2/3 of the stem; roots will form along it
• Mulch around plants to retain moisture and prevent soil splash
• Water consistently — 1–2 inches per week, at the base (not on leaves)
• Stake or cage plants to keep fruit off the ground
• Prune suckers on indeterminate varieties for larger fruit
• Feed every 2–3 weeks with tomato fertilizer once fruiting begins

Common Problems

• Blossom end rot — caused by inconsistent watering and calcium deficiency
• Cracking — caused by heavy rain after dry periods
• Blight — fungal disease; prevent with good air circulation and avoid wetting leaves
• Hornworms — large green caterpillars that can defoliate a plant overnight; pick off by hand
