Direct sun per day
Quick Answer
Jalapeños need well-draining soil with a pH of 6.0-6.8, about 1-2 inches of water per week (allowing soil to dry slightly between waterings), and 6-8 hours of direct sunlight daily.
Soil Requirements
Jalapeños prefer a loamy, well-draining soil rich in organic matter. The ideal pH range is 6.0-6.8. Amend heavy clay soil with compost and perlite to improve drainage. For containers, use a high-quality potting mix (not garden soil) and consider mixing in 20-30% perlite for better drainage. Avoid mixes with excessive slow-release fertilizer, which can burn young plants.
Watering Schedule
Water deeply but infrequently — about 1-2 inches per week. Allow the top inch of soil to dry between waterings. Overwatering is the most common mistake and leads to root rot, yellowing leaves, and poor fruit set. Container plants need more frequent watering than in-ground plants, especially in hot weather. Water in the morning to reduce disease risk. Mulch around plants to conserve moisture.
Most Common Mistake
Sunlight Needs
Jalapeño peppers need 6-8 hours of direct sunlight per day for best production. More sun generally means more peppers and hotter fruit. In extremely hot climates (100°F+), afternoon shade can help prevent sunscald on fruit. Morning sun is more important than afternoon sun.
