Seedling
2-3 weeksTiny green cotyledons emerge, developing into small seedlings with 2-4 true leaves
Keep soil consistently moist; maintain 70-80°F; provide bright light (14+ hours under grow lights); thin to strongest seedlings
Vegetative
4-6 weeksCompact plant grows bushy with multiple stems and increasingly leafy foliage; no flowers yet
Harden off before transplanting outdoors; space 18 inches apart; begin light fertilizing (balanced NPK); pinch top if desired for bushier growth
Flowering
3-4 weeksSmall white flowers appear at leaf axils throughout the plant; flowers are self-pollinating
Maintain consistent watering and warmth (65-80°F); provide bees or hand-pollinate if indoors; continue balanced fertilizing; support branches if needed
Fruiting
3-4 weeksGreen peppers develop and swell rapidly from spent flower bases; fruit reaches full blocky size before color change
Switch to higher-potassium fertilizer to promote fruiting; water deeply and regularly; ensure mulch in place; stake or support branches under heavy fruit load
Maturation & Harvest
Ongoing, 6-8+ weeks of productionGreen peppers transition to bright golden-yellow color, indicating full maturity; flavor and sweetness peak at this stage
Harvest peppers when fully colored for best flavor; continue watering and fertilizing for extended harvest; pick regularly to encourage more fruit production

Fun Facts
- 🌱 Yellow Marvel peppers become increasingly sweet as they mature from green to yellow—the longer you wait to harvest, the sweeter the pepper, because more sugars develop.
- 🌱 Bell peppers are technically fruits (berries), not vegetables, as they develop from the flower's ovary and contain seeds.
- 🌱 Yellow peppers contain more vitamin C than red peppers but slightly less than green peppers, yet are sweeter because the ripening process converts more starches to sugars.
