Care and Maintenance

Watering requirements

• Consistency: Even moisture prevents blossom end rot
• Amount: 1-2 inches per week including rainfall
• Method: Water at soil level to prevent leaf diseases
• Mulching: 2-3 inches of organic mulch to retain moisture

Fertilizing strategy

• Soil preparation: Work compost into soil before planting
• Balanced nutrition: Use balanced fertilizer (10-10-10)
• Frequency: Feed every 3-4 weeks during growing season
• Avoid over-nitrogen: Too much nitrogen means lots of leaves, few fruits
• Calcium matters: Prevents blossom end rot

Support and pruning

• Staking: Support plants when 12-18 inches tall
• Caging: Use sturdy tomato cages for support
• Pruning: Remove suckers below first flower cluster
• Pinching: Pinch first few flowers to encourage plant establishment

Harvesting Bell Peppers

Harvest timing

• Green stage: 60-80 days from transplant, full size but immature
• Colored stage: 80-100 days, peppers turn red, yellow, or purple
• Size indicator: 3-4 inches long for most varieties
• Feel test: Firm, glossy skin with good wall thickness

Harvesting technique

• Method: Cut stem with scissors or knife, do not pull
• Frequency: Harvest regularly to encourage continued production
• Storage: Green peppers last 1-2 weeks refrigerated; colored, use within 1 week
• End of season: Harvest all peppers before first frost

Common Problems and Solutions

Growing issues

• Blossom end rot: Dark, sunken spots on pepper bottoms from inconsistent watering or calcium deficiency
• Flower drop: Temperatures too hot (>90°F) or too cold (<55°F)
• Small fruits: Overcrowded plants, poor nutrition, or water stress
• Slow growth: Cool temperatures, poor soil, or root damage

Pest management

• Aphids: Spray with water, use insecticidal soap, encourage beneficials
• Hornworms: Handpick large caterpillars, use Bt spray
• Flea beetles: Row covers when young, diatomaceous earth
• Spider mites: Increase humidity, spray with water

Disease prevention

• Bacterial spot: Avoid overhead watering, choose resistant varieties
• Verticillium wilt: Practice crop rotation, remove infected plants
• Mosaic virus: Control aphids, remove infected plants immediately

Regional Growing Tips

Short-season areas (zones 3-6)

• Season extension: Use black plastic mulch and row covers
• Variety selection: Choose early varieties (60-70 days)
• Container growing: Move containers to protected areas
• Transplant size: Buy larger transplants for a head start

Hot-climate areas (zones 9-11)

• Timing: Plant fall through spring, avoid summer heat
• Afternoon shade: Protect from intense afternoon sun
• Consistent moisture: Daily watering may be needed
• Heat-tolerant varieties: Choose varieties bred for hot climates
