How Long Do Tomatoes Take to Grow?

Understand the complete tomato growing timeline

Quick Answer

Tomatoes take 60-80 days from transplant to first harvest, or 100-120 days when grown from seed. Early varieties (Early Girl, Juliet) mature in 55-65 days, while large heirlooms (Brandywine, Beefsteak) take 80-90+ days. Cherry tomatoes generally ripen faster than large slicing varieties.

Tomato Growing Timeline (From Seed)

Days 1-10

Germination

Seeds sprout in warm, moist conditions

Weeks 2-8

Seedling Growth

Grow under lights indoors until transplant-ready

Week 8-9

Hardening Off

Gradually acclimate to outdoor conditions

Week 9

Transplant Outdoors

After last frost, when soil is warm

Weeks 10-12

Vegetative Growth

Plant establishes, grows stems and leaves

Weeks 12-14

Flowering

Yellow flowers appear, pollination occurs

Weeks 14-18

First Harvest!

What Affects Growing Time?

Speeds Up Growth

  • Warm temperatures (70-85°F)
  • Full sun (8+ hours)
  • Consistent watering
  • Proper fertilization
  • Large containers
  • Healthy transplants

Slows Growth

  • Cool temperatures (below 60°F)
  • Insufficient light
  • Irregular watering
  • Nutrient deficiencies
  • Root-bound plants
  • Pest/disease stress

Why Tomatoes Won't Ripen

If your tomatoes stay green longer than expected, check these common causes:

Extreme heat: Above 95°F, tomatoes stop producing red pigment (lycopene). Ripening resumes when temperatures moderate.
Cool temperatures: Below 50°F, ripening slows dramatically. Pick tomatoes and ripen indoors before frost.
Insufficient light: Tomatoes need energy from sun to ripen. Shaded fruit takes longer.
Overwatering: Excess water dilutes sugars and slows ripening. Reduce watering as fruits mature.

Tips to Speed Up Ripening

Reduce watering: Slightly dry conditions signal the plant to ripen fruit faster.
Stop fertilizing: Once fruits are full-size, stop nitrogen fertilizer which promotes foliage over fruit.
Remove lower leaves: Redirects plant energy to ripening fruit rather than supporting excess foliage.
Pick at breaker stage: Tomatoes starting to show color can ripen indoors at 70°F.
Use a banana: Place tomatoes in a paper bag with a ripe banana - ethylene gas speeds ripening.

Frequently Asked Questions

How long from planting to harvest for tomatoes?

From transplanting seedlings outdoors, expect 60-80 days to first ripe tomatoes. Early varieties like Early Girl mature in 55-65 days, while large heirlooms like Brandywine take 80-90 days. Cherry tomatoes are generally faster (55-70 days) than large slicing tomatoes.

How long do tomatoes take to grow from seed?

Growing tomatoes from seed to harvest takes 100-120 days total. This includes: 5-10 days for germination, 6-8 weeks of indoor growth as seedlings, then 60-80 days after transplanting outdoors. Start seeds indoors 6-8 weeks before your last frost date.

Why are my tomatoes taking so long to ripen?

Several factors slow ripening: temperatures above 95°F or below 50°F (tomatoes ripen best at 70-85°F), insufficient sunlight, overwatering, excess nitrogen fertilizer, or simply growing a late-maturing variety. Red pigment (lycopene) doesn't form well in extreme heat.

Can I speed up tomato ripening?

To speed ripening: reduce watering slightly as fruits mature, stop fertilizing once fruits are full-size, remove lower leaves to redirect energy to fruit, pick at first color change and ripen indoors, or place in a paper bag with a banana (ethylene gas speeds ripening).
