Seedling
2-3 weeksTiny sprouted plants with 2-4 true leaves, reaching 2-3 inches tall
Maintain consistent moisture and warm temperatures (70-75°F). Provide bright light 14-16 hours daily indoors. Thin seedlings to strongest individuals.
Transplant Establishment
2-3 weeksYoung plants with 6-8 true leaves, 4-6 inches tall, ready for larger containers or garden beds
Harden off gradually over 7-10 days before transplanting outdoors. Plant deeper than original depth. Water gently and keep consistently moist. Protect from wind and strong sun initially.
Vegetative Growth
3-4 weeksPlants establishing root systems and foliage, 12-18 inches tall, no flowers yet
Water regularly and deeply. Begin light fertilizing every 2 weeks with balanced fertilizer. Support with stakes or cages early. Remove lowest leaves if soil-touching to prevent disease.
Flowering & Fruiting
2-3 weeks to flowering, then 3-4 weeks to mature fruitYellow flower clusters appear, followed by small green fruit development (size of peas to marbles)
Continue consistent watering; critical for fruit set. Switch to lower-nitrogen fertilizer (5-10-10) to encourage fruiting. Maintain stake/cage support. Prune excess foliage only if shading developing fruit.
Harvest & Production
4-8 weeks (continuous until frost)Fruits turn fully red, reaching ¾-1 inch diameter. Plants continue producing until frost
Harvest at full red color for best flavor. Pinch off new flowers 4-6 weeks before first frost to direct energy to ripening existing fruit. Continue regular watering and fertilizing every 2-3 weeks.

Harvest Tips
Pick fruits when fully red and slightly soft to touch, typically 50-65 days after transplanting. Harvest regularly to encourage continuous production. Early-season harvests keep plant productivity high. Tomatoes ripen best at temperatures between 68-77°F; fruit stops ripening above 85°F. Ripe fruit stores at room temperature for 3-5 days; refrigerate only if necessary (coldness reduces flavor).
Fun Facts
- 🌱 The Flash Series was specifically bred to mature quickly—sometimes producing ripe fruit in as little as 50 days from transplant, making it one of the fastest tomato varieties available for gardeners in short-season climates.
- 🌱 Flash tomatoes are technically berries, as they develop from a single ovary and contain seeds in their pulp. The name 'Flash' references both the speed of production and the bright flash of color when ripe fruit appears on the vine.
- 🌱 Cherry tomatoes like Flash contain lycopene and beta-carotene concentrations comparable to or higher than larger slicing tomatoes, making their small size deceptively nutritious.
