Growth Stages

1

Seedling

2-3 weeks

Tiny plants with cotyledons and first true leaves appearing; fragile with delicate roots

Keep soil moist but not waterlogged; provide bright light 12-16 hours daily under grow lights; maintain 65-75°F; thin to strongest seedling per cell

2

Vegetative Growth

4-6 weeks

Rapid stem and leaf development; plants growing 1-2 inches per week; developing robust root system and deeper green coloration

Harden off gradually before transplanting; maintain consistent moisture and nutrients; fertilize weekly with balanced fertilizer; transplant when 6-8 inches tall with 2-3 true leaves; pinch suckers on indeterminate varieties if needed

3

Flowering

3-4 weeks

Yellow flower clusters appearing along main stem; plants reaching full height; first flowers typically on lower axils

Maintain consistent watering to prevent flower drop and blossom end rot; provide phosphorus-rich fertilizer to encourage fruit set; ensure adequate light; temperatures 60-85°F optimal for fruit set; avoid high nitrogen which promotes foliage over flowers

4

Fruiting & Development

4-6 weeks

Small green fruit appearing behind flowers; rapid growth to full size; fruit gradually enlarging to 8-12 oz; color darkening from light green to mature red

Continue consistent deep watering; mulch around base; support heavy fruit with cages or stakes; reduce nitrogen, increase potassium; prune excessive foliage if fruit exposed to extreme sun; monitor for diseases and pests

5

Maturation & Harvest

Until frost or plant decline

Fruits reaching full size and deep red color; glossy skin development; firm yet slightly yielding to pressure when ripe

Harvest at full color for best flavor; can pick slightly early if disease or pests threatening; continue watering consistently; fruits progressively ripen throughout season; harvest before frost

Harvest Tips

Pick tomatoes when fully colored and slightly soft to touch for best flavor; vine-ripened fruits peak in taste; can pick at breaker stage (first blush of color) and ripen indoors if needed; harvest before first frost; twist gently or use pruners to avoid plant damage; store at room temperature away from direct sunlight; ripe tomatoes last 5-7 days on counter
