Jalapeno Brown Leaves: Fungus, Overwatering, Spacing

Brown, cupped leaves + close spacing = fungal issue worsened by daily watering and poor airflow.

Immediate Steps

• Water every 3–4 days only.
• Spray copper fungicide.
• Check leaf undersides for mites.
• Thin or transplant to 18" spacing.
• Afternoon sun only? Need 6+ hours direct.

Blossoms need time to pollinate; fruit will follow if plant recovers.
