Growing notes
Peppers want deep, even moisture — roughly 1–2 inches of water per week, more in heat. Water deeply at the base 2–3 times a week rather than a daily sprinkle; this draws roots downward and builds resilience. Keep the foliage dry and water in the morning to discourage fungal disease. Consistency is everything: erratic wet-then-dry swings trigger blossom-end rot and can cause flowers to drop. A 2–3 inch mulch of straw or shredded leaves steadies soil moisture and temperature. Containers dry out quickly and may need water daily in peak summer. A slight, deliberate dry-down can nudge hot peppers toward greater pungency near harvest.
