🌱 How to Care for Peppers & Chili Peppers to Prevent Bacterial Leaf Spot?

💧 How to Water

Water deeply whenever the top 2-3 cm of soil is dry, aiming for roughly 2.5 cm of water per week. Keep moisture consistent - drought stress followed by heavy watering causes blossom-end rot and split fruit. Water at the base and avoid overhead watering.

☀️ Lighting

Peppers need full sun: at least 6-8 hours of direct light outdoors daily, or 12-14 hours under grow lights indoors. Low light causes leggy stems, poor flowering, and fewer fruits.

🪴 Ideal Soil

Use a rich, well-draining, slightly acidic to neutral soil (pH 6.0-7.0) with plenty of organic matter. A loose sandy loam amended with compost or well-rotted manure gives the best combination of drainage and fertility; avoid heavy, waterlogged soils that promote root rot and phytophthora blight.
