Seedling
2-3 weeksTiny green shoots with cotyledons (seed leaves) emerge; first true leaves appear within 1-2 weeks
Keep soil moist but not soggy. Provide bright light or fluorescent grow lights 12-16 hours daily. Maintain 70-75°F temperature. Thin seedlings to prevent damping off.
Vegetative
3-4 weeks indoors; 1-2 weeks after transplanting outdoorsPlant develops sturdy stems, multiple sets of true leaves, and a strong root system. Compact, bushy growth habit typical of determinate varieties
Transplant to larger containers as needed. Provide consistent light and warmth (65-75°F). Begin hardening off 7-10 days before outdoor planting. Apply light fertilizer every 2 weeks.
Flowering
2-3 weeksSmall yellow flowers appear in clusters (trusses). Multiple flower clusters develop along the main stem and branches
Ensure pollination by gentle shaking or allowing natural air circulation. Maintain consistent watering to prevent blossom-end rot. Support plant with stakes or cages if needed. Continue regular feeding.
Fruiting
4-6 weeks per trussGreen marble-sized fruits develop and progressively ripen to bright red over 2-3 weeks. Multiple clusters ripen in succession throughout the season
Water consistently and deeply—critical during this stage. Mulch around base to retain moisture and regulate soil temperature. Remove lower leaves for air circulation and disease prevention. Fertilize every 2 weeks with balanced or slightly higher potassium fertilizer.
Harvest
Ongoing until first frost or plant decline (8-12 weeks typical)Fruits are fully red, slightly soft to gentle squeeze, and release easily from vine. Peak flavor and sweetness achieved
Pick ripe fruits every 2-3 days to encourage continued production. Use pruning shears to avoid damaging branches. Harvest before first frost in cooler zones. Green tomatoes can be ripened indoors.

Harvest Tips
Pick fruits when fully red and slightly yielding to pressure. Harvest every 2-3 days at peak ripeness for best flavor and to encourage continued production. Use pruning shears or carefully twist and remove to avoid branch damage. In cooler zones, pick all remaining fruits (even green ones) before the first frost and ripen indoors on a sunny windowsill. Fruits ripen best at 68-77°F.
Fun Facts
- 🌱 Cherry tomatoes evolved from wild tomato species in South America and are closer genetically to their wild ancestors than large slicing tomatoes, which explains their intense flavor concentration.
- 🌱 Sunburst Red is a determinate (bush-type) variety, meaning it grows to a fixed height and produces most of its fruit in a concentrated period, making it ideal for succession planting and canning.
- 🌱 Tomatoes contain compounds called terpenes that are responsible for their aroma; the combination in cherry tomatoes is often more intense than in larger varieties, making them especially aromatic when fresh off the vine.
