Growth Stages

1

Seedling

2-3 weeks

Tiny plants with 2-4 true leaves, delicate and pale green

Provide bright light (grow lights recommended), maintain warm soil temps (70-80°F), keep soil moist but not saturated, thin to strongest seedlings

2

Vegetative Growth

3-4 weeks

Bushy plants developing multiple leaf nodes, growing 6-12 inches tall, deep green foliage

Harden off gradually before transplanting outdoors, pinch growing tips to encourage bushiness, maintain consistent moisture, apply balanced fertilizer every 2 weeks

3

Flowering

2-3 weeks

Plant develops small white or pale purple flowers at leaf axils, plant reaches mature height of 12-24 inches

Switch to lower nitrogen, higher phosphorus fertilizer to promote flowering, ensure 8+ hours of direct sun daily, maintain even soil moisture, support branches if needed

4

Fruiting & Development

3-4 weeks

Flowers fade and peppers begin to form in clusters, initially green then color to red, yellow, orange, or purple depending on variety

Reduce nitrogen fertilizer, maintain consistent moisture for even ripening, thin fruit if overcrowded for larger peppers, prune lower leaves for air circulation

5

Mature & Harvest

4-8 weeks or until frost

Peppers reach full color intensity, plant is laden with ripe fruit in multiple colors, may continue producing through fall

Harvest ripe peppers regularly to encourage more fruit production, continue watering during dry spells, watch for late-season pests, can be brought indoors before frost

Harvest Tips

Peppers can be harvested at green stage or left to ripen to full color (red, yellow, orange, purple). For ornamental display, harvest at peak color. For eating, fully ripe peppers are sweeter and more flavorful. Use pruning shears or knife to cut fruit from plant rather than pulling. Harvest regularly to encourage continued production. In cooler climates, bring potted plants indoors before first frost to continue harvesting.

Fun Facts

  • 🌱 The vibrant colors in ornamental peppers develop due to different pigments (anthocyanins for purple, carotenoids for red/yellow/orange) that accumulate as the fruit ripens, similar to the color-changing process in autumn leaves.
  • 🌱 Colorado Mix peppers belong to the same species (Capsicum annuum) as bell peppers, jalapeños, and cayennes, but have been selectively bred for compact growth and prolific small-fruited production ideal for containers.
  • 🌱 Peppers are technically berries botanically speaking, and a single Colorado Mix plant can produce 50-100+ small peppers throughout the growing season under ideal conditions.
