Harvest Tips

Peppers can be harvested at the green stage or left to mature to deep red (sweeter, more nutritious). Use a sharp knife or pruners to cut peppers from the stem, leaving a short stub. Harvest regularly to encourage continued flowering and fruiting throughout the season. In cool climates, harvest all remaining peppers before the first frost.

Fun Facts

  • 🌱 Dark Red Scarlet peppers are both ornamental and edible, making them double-duty plants for gardeners wanting beautiful gardens that also produce food.
  • 🌱 Peppers require warm soil and air temperatures to thrive; they will not set fruit if nighttime temperatures drop below 60°F, which is why they're often started indoors in cooler climates.
  • 🌱 The color transformation from green to red indicates increasing levels of vitamin C and other antioxidants—mature red peppers contain up to three times more vitamin C than green peppers.
