Seedling
3-4 weeksSmall plants with 2-4 true leaves; delicate and pale green in color
Maintain warmth (70-80°F), consistent moisture, and bright indirect light. Start indoors 8-10 weeks before last frost. Thin to strongest seedlings.
Vegetative Growth
4-6 weeksBushy plant with multiple stems and dark green foliage; no flowers yet
Transplant outdoors after all frost danger and soil warms to 60°F+. Pinch growing tips to encourage bushiness. Stake or support as needed. Water consistently.
Flowering
2-4 weeksSmall white or pale purple flowers appear in leaf axils; plant becomes more compact
Continue consistent watering and fertilization every 2-3 weeks with balanced or slightly higher potassium formula. Ensure adequate sunlight for flower set.
Fruiting & Maturation
4-8 weeksSmall green peppers develop; gradually enlarge and ripen to red if left on plant longer
Maintain steady water and nutrient supply. Peppers are ready to harvest green or can mature to red. Support heavy fruit branches if needed.
Harvest & Production
6-12 weeks or until frostPlant produces continuous fruit over several months in warm climates; flowers and fruit at all stages present simultaneously
Regular harvesting encourages more flowering and fruiting. Continue watering and light fertilizing. Remove any diseased foliage. In cold climates, harvest before first frost.

Harvest Tips
Pepperoncini can be harvested green (at 1-2 inches long) for pickling, typically 60-90 days after transplant. Wear gloves when harvesting as even small peppers can irritate skin. Use pruning shears or pinch them off to avoid damaging branches. For pickled peppers, harvest before full maturity. If desired, allow peppers to ripen to red on the plant for sweeter flavor, though green peppers are traditional for pickling. In warm climates, plants produce continuously until frost.
