Carolina Reaper peppers
Annual · Solanaceae
Carolina Reaper is a very late, extremely hot red pepper grown for gardeners who want a true end-of-season challenge. The wrinkled pods have a fruity aroma before the heat lands, but they need sustained warmth and a long season to color properly. This variety suits experienced growers who can start peppers early and provide dependable summer heat.

Common Problems
blossom-drop
Cause: Day temperatures above the mid-90s F or warm nights above the mid-70s F reduce pollen viability.
Prevention: Use mulch, steady irrigation, and afternoon airflow; avoid pushing soft growth with excess nitrogen.
aphids
Cause: Tender new growth and stressed plants attract sap-feeding insects that can vector virus.
Prevention: Inspect undersides of leaves, wash off early colonies, and use insecticidal or neem sprays only as needed.
leaf-spot
Cause: Humid weather and wet foliage favor bacterial and fungal spotting.
Prevention: Space well, water at soil level, and remove badly infected leaves early.
