Best Peppers for Zone 10

Start your spring pepper seeds indoors in late December or early January, timing transplants for mid to late February after your average last frost of January 31st. However, don't rush – a late cold snap can devastate young transplants, so have row covers ready or wait until soil temperatures consistently reach 65°F. Your fall crop should be started from seed in late June or July, with transplants going out in August when the worst heat begins to break.

Summer heat management is critical in Zone 10. Provide afternoon shade during peak summer months using shade cloth (30-50%) or plant peppers where they'll get morning sun and afternoon protection from taller plants or structures. Mulch heavily to keep soil cool and maintain consistent moisture – peppers hate wet feet, but they also can't handle drought stress in your intense heat. Drip irrigation works better than overhead watering, which can promote disease in the humid conditions.

Watch for common Zone 10 pepper problems: bacterial spot thrives in your humidity, so ensure good air circulation and avoid overhead watering. Whiteflies and aphids can explode in the warm conditions, while root-knot nematodes are persistent soil pests. Rotate your pepper beds yearly and consider soil solarization during the hottest part of summer to reduce nematode populations.
