2 If the soil is waterlogged, repot the chili plant in a well-draining medium enriched with perlite to improve aeration and prevent root suffocation.

3 If the plant is suffering from drought, ensure consistent watering and consider using a moisture-retaining amendment like vermiculite to stabilize hydration.

Temperature Shock

Chili peppers prefer consistent warm temperatures; sudden exposure to cold drafts (below 55°F/13°C) or extreme heat spikes can trigger a physiological stress response resulting in abscission.

1 Relocate the plant to a stable environment away from cold drafts, air conditioning vents, or direct heat sources to maintain temperatures between 65°F and 85°F.

2 Monitor soil moisture levels closely during temperature fluctuations to ensure the plant is not experiencing simultaneous drought or waterlogging stress.

1 Immediately inspect the roots for dark, mushy, or foul-smelling decay and prune away any dead tissue using sterilized tools.

2 Repot the plant into a fresh, sterile medium with improved drainage, incorporating perlite to increase aeration and prevent further rot.

3 Transition the plant to a container with superior drainage and use a moisture meter to ensure the soil is not staying waterlogged.
