How to know when hot peppers are ready to harvest
Colour is a strong ripeness indicator. Every pepper starts green and moves toward its own mature colour, whether that’s red, orange, yellow, or deep purple, depending on the variety.
Size is a general guideline, not a hard rule. Most hot peppers reach three to five inches at full size, but growing conditions can stunt them or let them grow bigger than normal. My smallest red jalapeño this year came in well under that range and was still perfectly ready to pick.
Those pale, thread-like lines on the skin are called corking. It happens when the pepper’s rapid growth slightly cracks the surface, and it’s a sign of maturity, not a problem.
A few other signs mean it’s time to pick, even if a pepper hasn’t fully ripened. A deep crack that opens into the flesh, pest damage, stress from extreme heat or weather, or a coming frost are all good reasons to harvest early rather than wait for perfect colour or size.
When in doubt, pick it. A firm pepper harvested a touch early beats one left too long to split, rot, or attract pests.
