Why does your Capsicum cubana Deep Orange have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Capsicum species are highly sensitive to sudden changes in temperature, especially cold drafts or sudden heat waves. If the plant was recently moved or experienced a sharp drop in night temperatures, it will shed leaves to conserve energy.
Excessive moisture at the base of Cuban Peppers leads to anaerobic conditions, causing root decay. As roots die, they can no longer support foliage, leading to rapid, premature leaf abscission.
Peppers require consistent moisture; extreme drought causes the plant to drop leaves as a survival mechanism to reduce transpiration. This is often accompanied by wilting before the actual leaf drop occurs.
A severe lack of nitrogen prevents the plant from maintaining its foliage. While usually a slower process, acute deficiency can cause older leaves to yellow and drop suddenly during high growth phases.
