Seedling
4-6 weeksSmall plants with 2-4 true leaves, compact growth
Start indoors 8-10 weeks before last frost. Keep soil warm (70-80°F) and moist. Provide grow lights 14-16 hours daily. Thin seedlings to strongest plants.
Vegetative
6-8 weeksPlant grows taller and bushier with increasing foliage; no flowers yet
Transplant outdoors after last frost danger and soil warms to 60°F+. Harden off seedlings over 7-10 days. Pinch top growth once or twice to encourage branching. Water and fertilize regularly with balanced fertilizer.
Flowering
3-4 weeksSmall white or cream flowers appear at leaf nodes
Ensure pollination by gently shaking plants or allowing bee access. Maintain consistent watering and switch to phosphorus-rich fertilizer to support fruit set. Mulch around base to retain moisture and regulate temperature.
Fruiting & Maturation
3-4 weeks green to matureSmall green peppers develop and enlarge; gradually darken to deep brown-black at full maturity
Support heavy fruit clusters with stakes or cages. Reduce nitrogen fertilizer once peppers set. Maintain consistent watering for uniform ripening. Pick peppers at green stage or allow full 2-3 weeks extra for color change and flavor development.
Harvest
Ongoing until frostMature brown-black peppers ready for picking or drying
Use sharp pruners or knife to cut peppers to avoid damaging plant. Can be harvested green or allowed to fully ripen. For drying, leave on plant longer or dry harvested peppers in warm location.

Harvest Tips
For fresh use, pick when peppers are green (1.5-3 inches long) or mature brown-black (2-4 inches). For drying and traditional use, allow peppers to fully mature on plant until dark brown-black, which takes an additional 2-3 weeks after green stage. Peppers will be sweeter and have deeper, smoky flavor when fully mature. Harvest regularly to encourage continuous production throughout season.
Fun Facts
- 🌱 Mulato peppers get their name from their dark brown-black color, similar to mulato chocolate. They are the same plant as poblano peppers but allowed to fully mature on the vine.
- 🌱 When dried, mulato peppers develop complex notes of chocolate, tobacco, and smoke, making them essential to authentic mole negro (black mole), one of Mexico's most elaborate and ancient sauces.
- 🌱 A single mature Mulato Poblano plant can produce 15-25 peppers in a season, providing substantial harvests for fresh use, roasting, or drying throughout the growing period.
