Seedling
3-4 weeksEmergence of seed leaves followed by first true leaves; small green plants 2-4 inches tall
Provide bright light (14-16 hours), maintain soil moisture, avoid overwatering. Keep temperature 70-75°F. Fertilize weekly with half-strength liquid fertilizer after true leaves appear.
Transplant/Early Growth
2-3 weeks indoors before transplantingStocky plants 6-10 inches tall with 4-6 true leaves, ready for hardening off and transplanting outdoors
Harden off plants by gradually exposing to outdoor conditions over 7-10 days. Plant in garden 24 inches apart after last frost. Water gently after planting.
Vegetative/Flowering
3-4 weeksBushy growth with multiple branches and flower clusters beginning to form; flowers appear in clusters
Provide consistent water and nutrients. For determinate varieties like Trailblaze, minimal pruning is needed. Support with stakes or cages early. Remove lower leaves once flowering begins to improve air circulation.
Fruit Set/Development
3-4 weeksDeveloping green fruits at varying sizes; fruits enlarge and begin color change
Maintain consistent watering (1-2 inches weekly). Fertilize every 2-3 weeks with balanced or fruiting formula. Ensure good air circulation. Watch for disease symptoms.
Ripening/Harvest
2-3 weeks of active harvestFruits turn deep red and reach full size; plant becomes dense with mature fruit
Continue regular watering but reduce slightly if rains are heavy. Harvest ripe fruits regularly to encourage continued production. Fruits ripen all at once due to determinate growth habit.

Harvest Tips
Harvest when fruits are deep red and slightly soft to slight pressure. Trailblaze is a determinate variety that ripens most fruits within a concentrated timeframe (2-3 weeks). Twist gently or use pruning shears. Can harvest at 'breaker stage' (first blush of color) and ripen indoors. All fruit typically ripens by end of season.
Fun Facts
