Seedling
2-3 weeksTiny seedlings with seed leaves (cotyledons) appear within 5-10 days. First true leaves emerge shortly after.
Keep soil moist but not waterlogged. Maintain 70-75°F. Provide bright light or grow lights 14-16 hours daily. Keep lights 2-3 inches above seedlings.
Vegetative Growth
4-6 weeks from germinationPlant develops several sets of true leaves and grows taller. Stems are sturdy and green. Plant may be 6-10 inches tall before transplanting.
Transplant to larger containers when 2-3 sets of true leaves appear. Harden off before moving outdoors. Maintain consistent moisture and warmth (65-75°F). Begin fertilizing lightly with balanced fertilizer.
Flowering
2-3 weeksSmall yellow flowers appear in clusters (trusses). Plant becomes bushier and more robust. Flowering typically begins 4-6 weeks after transplanting to garden.
Reduce nitrogen fertilizer; increase phosphorus and potassium to support flowering. Water consistently. Remove some lower leaves as plant grows to improve air circulation. Do not over-water or over-fertilize nitrogen, which promotes foliage over flowers.
Fruiting
4-6 weeks to first ripe fruit; 2-4 weeks for continued harvestFlowers set fruit; small green tomatoes develop into full-sized fruits. Fruits gradually change from green to red as they mature. Jersey produces compact clusters of medium fruits.
Water deeply and consistently—1.5-2 inches per week depending on weather. Mulch around base to regulate soil moisture and temperature. As determinate variety, Jersey produces most fruit within concentrated timeframe. Prune minimal foliage (only lower leaves touching ground). Support branches with stakes or cages as they become heavy.
Harvest & Decline
4-8 weeks of harvestingTomatoes ripen to full red color and can be harvested. As determinate variety, fruiting declines after 4-6 weeks of production. Plant may continue producing but with reduced vigor.
Pick tomatoes when fully colored and slightly soft. Jersey produces a concentrated crop, ideal for sauce-making or preserving. Monitor for late blight and other diseases. Continue watering until frost or plant senescence.

Harvest Tips
Harvest Jersey tomatoes when fully red and slightly yielding to gentle pressure. Jersey is a determinate variety that produces most of its crop within a 4-6 week window, making it excellent for canning and sauce production. Pick fruit in early morning when firm. Tomatoes can be harvested at 'breaker stage' (first blush of color) and ripened indoors in a warm location if needed. Jersey holds its color well and doesn't crack easily, making it ideal for fresh market or processing.
