Growing Tips

  • Heat level varies with water stress — less water = hotter peppers.
  • Start indoors 8–10 weeks before transplanting for best results.
  • Pick jalapenos when dark green for milder flavor, or let them turn red for sweeter heat.
  • Smoke red jalapenos to make chipotle — fully ripe red ones are perfect for this.
  • Wear gloves when processing — capsaicin oil stays on hands for hours.

Common Mistakes

  • Transplanting in cool weather — jalapenos need 65°F+ soil temperature.
  • Overwatering for milder peppers — this doesn't work and causes root rot.
  • Touching eyes after handling — always wash hands thoroughly (or use gloves).
  • Harvesting all at once — keep picking to encourage continued production.
