Seedling
3-4 weeksTiny plants with 2-4 true leaves, delicate and pale green
Keep soil moist but not waterlogged. Provide 14-16 hours of bright light daily. Maintain temperatures of 70-75°F. Thin seedlings if crowded.
Vegetative Growth
4-6 weeksBushy, compact plants developing multiple branches and dark green foliage; no flowers yet
Harden off transplants before moving outdoors. Plant after last frost when soil temps reach 60°F. Pinch tops early to encourage branching. Fertilize every 2-3 weeks with balanced fertilizer.
Flowering
3-4 weeksWhite or pale flowers appear at branch nodes; small buds and open blossoms visible on plant
Maintain consistent watering and warmth (70-85°F ideal). Support with stakes if branches bend. Reduce nitrogen fertilizer, switch to higher phosphorus formula to encourage fruit set.
Fruiting
4-6 weeksSmall green peppers develop where flowers were; fruits grow rapidly and change color from green to red
Water consistently and deeply. Fertilize every 2-3 weeks with balanced or potassium-rich fertilizer. Provide mulch to retain moisture and regulate soil temperature. Prune excess foliage only if shading fruit.
Harvest
Ongoing from mid-summer until frostPeppers reach full size (3-4 inches long) and develop vibrant red color; firm and glossy
Harvest when fully red for maximum sweetness and nutritional content. Use pruning shears to cut peppers, don't pull. Continue harvesting to encourage more production. Most peppers mature by late summer/early fall.

Harvest Tips
Harvest peppers when they reach full size and turn completely red for sweetest flavor (usually 80-100 days from transplant). Use clean pruning shears to cut at the stem, leaving some fruit to continue development. Harvest regularly to stimulate continued production. Peppers can be harvested at green stage if needed, but red peppers are sweeter and contain more vitamins. Early morning harvest yields crispest peppers.
Fun Facts
- 🌱 Stockton Red is named after Stockton, California, where it was developed and became a popular commercial variety in the early 20th century due to its reliability and productivity.
- 🌱 Red peppers are actually mature green peppers—the longer a pepper stays on the plant, the more it ripens to red, developing increased sweetness and up to three times more vitamin C than green peppers.
- 🌱 Peppers are technically berries botanically, and a single healthy Stockton Red plant can produce 20-30+ peppers in a season, making it one of the most prolific home garden pepper varieties.
