Starting and Planting

Start seeds indoors 8–10 weeks before the last frost (mid-January to early February in Chico) in warm soil (70–85°F for reliable germination). Use seed-starting mix and provide bright light or grow lights. Transplant mid-March to early April after frost risk passes and nighttime temperatures stay above 55°F (soil ~60°F+). Space plants 18–24 inches apart in rows 2–3 ft apart. Chico’s mild springs allow an early start for strong plants and extended harvests before the hottest summer days.

Location and Soil

Choose a full-sun site (8–10+ hours daily)—Chico’s intense summer sun boosts pod size, color, and rich grassy flavor. Avoid shaded or low-lying spots. Use well-drained, fertile loamy soil; amend common Central Valley clay with plenty of compost or organic matter for improved drainage and nutrients. Aim for pH 6.0–7.5. Incorporate balanced fertilizer or compost at planting—Anaheims are moderate feeders.

Support and Pruning

Plants can become top-heavy with long fruits, so provide light staking or small cages early, especially in windy Sacramento Valley conditions. Pruning is minimal: remove lower leaves for better airflow and to prevent soil splash. Pinch the growing tip early if you want bushier growth and more branches.

Watering and Feeding

Water deeply and consistently—1–2 inches per week, increasing during July–August heat waves—to prevent blossom drop or sunscald. Use drip irrigation or soaker hoses at the base to keep foliage dry and reduce evaporation in Chico’s arid conditions. Mulch thickly with straw or wood chips to retain moisture and cool roots. Fertilize every 3–4 weeks with a balanced organic fertilizer; shift to higher phosphorus/potassium once flowering begins to support large, thick-walled pods.

Pest and Disease Management

Chico’s low humidity greatly reduces fungal diseases like powdery mildew or blight, but good spacing and airflow still help. Watch for aphids, flea beetles, or hornworms—control with neem oil, insecticidal soap, or hand-picking. Companion plant with basil or marigolds for natural pest deterrence. Blossom end rot can occur with uneven watering—maintain steady moisture and add gypsum if calcium is low. Anaheim peppers are generally resilient and productive in local hot, dry conditions.

Harvest and Flavor Tips

Harvest green Anaheim peppers when they reach full size (6–8 inches) and are firm for the classic mild, grassy flavor—perfect for roasting, stuffing, or slicing. Let some ripen to red for sweeter taste before drying or using fresh—pick regularly to encourage more production through October. Roast and peel the skin for chiles rellenos or dice into salsas and sauces. In Chico’s heat, consistent watering keeps walls thick and juicy without bitterness. Store fresh in the fridge for 1–2 weeks or freeze/roast for longer use.

Anaheim peppers are an outstanding, mild-heat choice for Chico gardens—versatile, productive, and perfect for authentic Southwestern and Mexican dishes all season long!
