Support branches with stakes if heavily loaded, maintain steady watering to prevent fruit cracking and blossom end rot, continue fertilizing every 2 weeks
Harvest & Maturation
6-8 weeks until frostPeppers reach full red color and maximum heat; plant continues producing throughout season

Harvest Tips
Harvest peppers when they turn bright red for maximum heat (80,000-100,000+ Scoville Heat Units); can pick at green stage if desired for milder flavor. Peppers continue ripening on the plant. Use sharp scissors or pruners to cut rather than pull to avoid damaging branches. Regular harvesting encourages continued production throughout the season. Peak harvest occurs mid-summer through frost.
