Seedling
4-6 weeksSmall plants with 2-3 pairs of true leaves; delicate and tender
Keep soil moist but not waterlogged; maintain 70-80°F; provide bright light or grow lights 14-16 hours daily; fertilize lightly once true leaves appear
Vegetative Growth
3-4 weeksPlants develop multiple stems and branch structure; leaves are dark green and abundant
Transplant outdoors after last frost when soil reaches 60°F; harden off gradually; provide consistent moisture; support with stakes if needed; prune suckers between main branches for better air circulation
Flowering
3-4 weeks, overlapping with fruitingSmall white or pale purple flowers appear in leaf axils; flowers are self-fertile
Maintain consistent watering and warm temperatures (70-85°F ideal); avoid excess nitrogen which promotes foliage over flowers; light fertilizing with balanced or slightly higher phosphorus formula; ensure good air circulation
Fruiting & Growth
4-6 weeksSmall green peppers develop and enlarge rapidly; plants become laden with developing fruits
Maintain steady watering; mulch around base to retain moisture and regulate temperature; support heavy fruit with stakes or cages; continue light fertilizing every 2-3 weeks; remove any diseased leaves
Maturation & Harvest
6-12 weeks depending on location and first frost datePeppers turn deep red at full maturity; walls thicken and sweeten; plants may produce continuously until frost
Harvest green peppers at any time for cooking, or allow to fully ripen to red for maximum sweetness; pick regularly to encourage continued production; continue watering and fertilizing for extended harvest; remove any yellow or diseased foliage

Harvest Tips
Harvest peppers green for cooking use, or allow to ripen fully to deep red for maximum sweetness and vitamin C content. Use sharp knife or pruners to cut peppers from the stem; avoid pulling which can damage branches. Costa Rica Red peppers continue producing until the first hard frost, often yielding 15-20+ fruits per plant in good conditions.
Fun Facts
- 🌱 Costa Rica Red peppers turn from green to red as they mature, and the longer they stay on the plant, the sweeter they become due to increased sugar content and carotenoid development.
- 🌱 Bell peppers are actually fruits botanically (they contain seeds), not vegetables, though they're culinarily treated as vegetables.
- 🌱 A single Costa Rica Red plant can produce 15-25+ peppers in a season under optimal growing conditions, making it an exceptionally productive variety.
