Keep soil moist but not waterlogged. Provide bright light (grow lights 2-3 inches above plants). Maintain 65-75°F temperature.
Vegetative Growth
3-4 weeksBushy growth with multiple branches, flowering hasn't begun; plant may reach 3-4 feet tall
Begin staking or caging early. Provide consistent watering and balanced fertilizer. Remove lower leaves as plant grows to improve air circulation.
Flowering
3-4 weeksSmall yellow flowers appear in clusters; plant continues vegetative growth
Reduce nitrogen fertilizer; increase phosphorus and potassium to encourage fruit set. Maintain consistent watering. Gently shake flowers to aid pollination.
Fruiting & Development
4-6 weeksGreen fruits develop and gradually enlarge; color transition from green to purple-black begins at maturity
Provide consistent water and support as fruits develop. Remove some foliage if fruits get sunburned. Prune excess leaf cover in late season to allow sun exposure for better color.
Harvest
4-8 weeks (ongoing production)Fruits reach full dark purple-black color with slight give to gentle pressure
Harvest when fully colored but still slightly firm. Can harvest at 'breaker stage' (first blush of color) and ripen indoors. Pick regularly to encourage continued production.

Harvest Tips
Harvest when fruits are fully dark purple-black and slightly soft to gentle pressure, typically 75-85 days after transplanting. Tomatoes continue to ripen after picking, so you can harvest at the 'breaker stage' (first appearance of color) and let them finish ripening indoors at room temperature. Regular harvesting encourages continued fruit production throughout the season. For best flavor, allow fruits to fully ripen on the vine in warm weather.
Fun Facts
- 🌱 The deep purple-black color of Aztec Purple tomatoes comes from anthocyanins, the same compounds that give blueberries and blackberries their color, making these tomatoes unique among traditional red tomato varieties.
- 🌱 This is a true indeterminate variety, meaning it continues growing and producing fruit throughout the season until frost, unlike determinate bush types that produce all fruit at once.
- 🌱 The name 'Aztec Purple' pays homage to the indigenous peoples of Mexico, where tomatoes were originally domesticated thousands of years ago before spreading to Europe and the rest of the world.
