“When will I have tomatoes?”
This is THE question every new tomato grower asks approximately 47 times while obsessively checking their plants daily.
The answer is: It depends. (I know, frustrating. But let me explain.)
The time from seed to ripe tomato varies based on variety, growing conditions, and whether you start from seed or transplants. Let me break down the timeline so you know exactly what to expect.
## The Quick Answer
From transplanting to harvest: 60-100+ days, depending on variety
From seed to harvest: Add 6-8 weeks for seed starting, so 100-140+ days total
For impatient people: Cherry tomatoes are fastest (50-65 days), early varieties next (60-70 days), large heirlooms slowest (80-100+ days)
## Understanding “Days to Maturity”
Every seed packet lists “days to maturity”—like “Early Girl: 50-60 days.”
Important: This usually means days from transplanting to first ripe fruit, NOT from seed!
So if your packet says “70 days,” you need to add 6-8 weeks for starting seeds indoors.
Total timeline:
– 6-8 weeks: Indoor seed starting
– 70 days: From transplanting to harvest
– Total: ~14-16 weeks (3.5-4 months) from seed to ripe tomato
## Complete Timeline: Seed to Harvest
### Weeks 1-2: Germination
– Plant seeds indoors 6-8 weeks before last frost
– Seeds germinate in 5-10 days
– First leaves (cotyledons) appear
What’s happening: Seeds absorbing water, activating, sprouting
### Weeks 2-4: Seedling Stage
– True leaves develop
– Seedlings growing slowly
– May pot up to larger containers
What’s happening: Building root system, starting photosynthesis
### Weeks 4-6: Vegetative Growth
– Rapid leaf growth
– Stems thickening
– Roots filling containers
What’s happening: Plant bulking up before transplant
### Weeks 6-8: Hardening Off & Transplanting
– Gradually expose seedlings to outdoor conditions
– Transplant after last frost
– Plant may experience slight transplant shock
What’s happening: Adapting to outdoor environment
### Weeks 8-10 (2-4 weeks after transplanting): Establishment
– Plant adjusting to new location
– Root system expanding
– Visible growth may be slow (roots are growing underground)
What’s happening: Building foundation for explosive growth
### Weeks 10-14 (4-8 weeks after transplanting): Vegetative Growth
– Rapid upward and outward growth
– Lots of foliage
– Increased watering and feeding needs
What’s happening: Plant hitting its stride, storing energy for fruiting
### Weeks 12-16 (6-10 weeks after transplanting): Flowering
– First flower clusters appear
– Flowers bloom
– Pollination occurs (bees, wind)
What’s happening: Reproductive stage beginning
### Weeks 14-18 (8-12 weeks after transplanting): Fruit Set
– Flowers become tiny green tomatoes
– Fruit sizing up
– Plant still growing (if indeterminate)
What’s happening: Fruit developing, plant needs LOTS of nutrients and water
### Weeks 16-20+ (10-14+ weeks after transplanting): Ripening
– Green tomatoes starting to change color (“breaker” stage)
– First ripe tomatoes!
– Continuous harvest (indeterminate) or all at once (determinate)
What’s happening: You’re FINALLY eating tomatoes!
## Timeline by Variety Type
### Early Varieties (50-60 days)
Examples: Early Girl, Fourth of July, Sub Arctic Plenty, Stupice
Transplant to harvest: 50-60 days (7-9 weeks)
Seed to harvest: 12-14 weeks (3-3.5 months)
Best for: Short growing seasons, impatient gardeners, getting tomatoes ASAP
### Midseason Varieties (65-75 days)
Examples: Better Boy, Celebrity, Roma, most hybrids
Transplant to harvest: 65-75 days (9-11 weeks)
Seed to harvest: 14-17 weeks (3.5-4 months)
Best for: Most climates, reliable production
### Late/Heirloom Varieties (75-100+ days)
Examples: Brandywine, Cherokee Purple, Mortgage Lifter, most heirlooms
Transplant to harvest: 80-100+ days (11-14+ weeks)
Seed to harvest: 18-22+ weeks (4.5-5.5+ months)
Best for: Long growing seasons, flavor over speed, patient gardeners
### Cherry Tomatoes (50-65 days)
Examples: Sweet 100, Sungold, Tiny Tim, Red Robin
Transplant to harvest: 50-65 days (7-9 weeks)
Seed to harvest: 12-15 weeks (3-3.5 months)
Best for: Fastest harvests, container growing, guaranteed success
## Factors That Affect Growing Time
### Temperature
Ideal: 70-85°F (21-29°C) during the day
Too cold (below 55°F): Growth slows or stops
Too hot (above 95°F): Growth slows, flowers drop
Impact: Cold spring = longer time to maturity. Hot summer = faster growth (until it’s TOO hot).
### Sunlight
Ideal: 6-8+ hours direct sun
Less sun: Slower growth, delayed fruiting, lower yields
Impact: Full sun = faster growth. Partial shade = add 1-2 weeks to timeline.
### Soil Quality
Good soil (nutrient-rich, well-draining): Faster growth
Poor soil (compacted, depleted): Slower growth
Impact: Great soil can shave a week or two off harvest time.
### Water & Nutrients
Consistent care: Plants stay on track
Neglect: Stress slows growth significantly
Impact: Inconsistent watering can delay harvest by weeks.
### Plant Health
Healthy plants: Hit expected timeline
Stressed/diseased plants: Take much longer (if they produce at all)
Impact: Pests and disease can delay or ruin harvest.
## How to Speed Up Tomato Growth
Want tomatoes faster? Here’s how:
### 1. Choose Early Varieties
The single biggest time-saver. “Early Girl” produces weeks before “Brandywine.”
### 2. Start Seeds Indoors Early
Start seeds 6-8 weeks before last frost (not earlier—they’ll get leggy). This gives you bigger transplants ready to produce sooner.
### 3. Use Black Plastic Mulch
Black plastic warms soil, accelerating growth early in the season. Can shave 1-2 weeks off harvest time.
### 4. Provide Optimal Conditions
– Full sun: No compromises
– Warm soil: Wait until soil is 60°F+ before transplanting
– Excellent soil: Compost-rich, well-draining
– Consistent water: No stress
– Regular feeding: Every 2-3 weeks
### 5. Use Wall O’ Water or Cloches
Plant protectors trap heat, allowing earlier planting and faster growth.
### 6. Buy Larger Transplants
Starting with bigger plants gives you a 2-3 week head start. Costs more, but you get tomatoes sooner.
### 7. Prune for Faster Fruiting
Removing suckers on indeterminate varieties focuses energy on fruiting rather than endless foliage.
### 8. Choose Warm-Season Planting
Don’t rush to plant in cool spring. Waiting for truly warm weather results in faster growth overall (cold-shocked plants sit and sulk for weeks).
## When to Expect Your First Tomato
If you transplant May 15:
– Early varieties (60 days): Mid-July
– Midseason (70 days): Late July
– Late varieties (85 days): Mid-August
If you start seeds indoors March 1:
– Transplant: Around May 1 (8 weeks later)
– Early varieties: Early to mid-July
– Midseason: Late July
– Late: Mid-August
Cherry tomatoes are usually FIRST, regardless of transplant date.
## How Long Do Plants Keep Producing?
### Determinate Tomatoes
Produce all fruit within 1-2 weeks, then stop.
Total producing time: 2-3 weeks
### Indeterminate Tomatoes
Produce continuously until frost kills them.
Total producing time: 2-4 months (until frost)
This is why indeterminates give higher total yields—they keep producing for MONTHS.
## Adjusting for Your Climate
### Short Season (Zone 3-5)
– Growing season: 90-120 days
– Strategy: Choose early varieties (50-65 days)
– Start seeds early: Maximize available time
– Use season extenders: Cloches, row covers
### Moderate Season (Zone 6-7)
– Growing season: 150-180 days
– Strategy: Grow anything (early to midseason varieties are reliable)
– Timeline: Follow standard timelines above
### Long Season (Zone 8-11)
– Growing season: 200+ days (or year-round)
– Strategy: Grow heirlooms and late varieties for best flavor
– Bonus: Can do spring AND fall plantings
## What If It’s Taking Longer Than Expected?
Possible reasons:
– Cool temperatures slowing growth
– Not enough sun
– Poor soil or inadequate feeding
– Plant is stressed (pests, disease, inconsistent water)
– You’re just impatient (it FEELS like forever!)
What to do:
– Check conditions (sun, water, nutrients)
– Address any obvious problems
– Be patient—they’ll come!
## The Bottom Line
From seed to ripe tomato: 3-5 months depending on variety and conditions.
From transplant to harvest: 50-100+ days depending on variety.
Fastest tomatoes: Cherry tomatoes and early varieties (50-65 days)
Slowest tomatoes: Large heirlooms (85-100+ days)
Want tomatoes ASAP? Plant Early Girl or cherry tomatoes, start seeds indoors early, provide optimal conditions, and be patient.
Growing tomatoes is a test of patience. But trust me—when you bite into that first sun-warm, vine-ripened tomato, you’ll forget all about the waiting.
And then you’ll plant twice as many next year.
It’s a delicious cycle. 🍅
