Why does your Capsicum annuum Salsa Red have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Capsicum annuum is highly sensitive to rapid fluctuations in temperature, especially sudden drops below 50°F (10°C) or extreme heat spikes. This triggers a stress response where the plant sheds leaves to reduce transpiration and protect its core.
Inconsistent moisture levels cause the plant to drop leaves; either waterlogged soil leads to anaerobic conditions and root rot, or extreme dryness forces leaf abscission. Pepper plants require stable, well-draining moisture to maintain turgor pressure.
This fungal pathogen attacks the stems and roots of pepper plants, often leading to rapid wilting and sudden defoliation. The infection disrupts the vascular system, preventing water from reaching the upper leaves.
A severe lack of nitrogen prevents the plant from maintaining its foliage, often resulting in older leaves turning yellow (chlorosis) before dropping. This is common in pepper plants grown in depleted or heavily leached soils.
