Growth Stages

1

Seedling

2-3 weeks

Tiny sprouted plants with cotyledons and first true leaves appearing

Maintain warm temperatures (70-75°F), provide bright light, keep soil moist but not soggy, thin seedlings to 1-2 inches apart

2

Vegetative

4-6 weeks after transplanting

Young plants developing compound leaves and growing taller; no flowers yet

Gradually harden off transplants over 7-10 days before planting outdoors. Plant deeply to encourage root development. Install stakes or cages early. Keep consistently watered.

3

Flowering

3-4 weeks

Small yellow flowers appear in clusters; plant becomes bushier

Maintain consistent watering; avoid excess nitrogen which promotes foliage over flowers. Prune suckers on determinate varieties if desired. Ensure adequate calcium to prevent blossom-end rot.

4

Fruiting

3-4 weeks

Small green cherry tomatoes form and gradually enlarge, then transition from green to bright red

Continue consistent watering without overwatering. Support heavy fruit clusters. Monitor closely for late blight and early blight despite resistance. Fertilize moderately with balanced fertilizer.

5

Harvest

2-4 weeks of peak harvest

Fully red, ripe cherry tomatoes ready for picking; plant may produce additional waves of fruit

Pick ripe tomatoes regularly to encourage continued production. Patriot Scarlet is determinate, so most fruit ripens within a concentrated window. Continue watering and monitoring for disease.

Harvest Tips

Pick tomatoes when fully red and slightly soft to the touch.

Tomatoes can be harvested at the breaker stage (first showing color) and ripened indoors if needed. Use gentle twisting motion or scissors to avoid damaging the plant.
