Growing Peppers in Zone 4A

Peppers love heat even more than tomatoes. Both sweet and hot varieties need warm soil and plenty of sun.

Zone 4A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Wait until soil is 65°F+ before transplanting
• Don’t over-fertilize with nitrogen — it produces leaves over fruit
• Pinch first flowers to encourage bushier plants
• Peppers prefer slightly acidic soil (pH 6.0-6.8)
• Harvest regularly to encourage continued production

Companion Planting

Good companions: tomatoes, basil, carrots, onions

Avoid planting near: fennel, kohlrabi

Harvest Timeline

60-90 days from transplant
