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

Peppers split into sweet and hot, and within each, days-to-maturity is the lever for short seasons — the early types ripen before a cool-zone summer runs out.

  • Sweet bellCalifornia Wonder is the classic blocky, thick-walled bell (~75 days).
  • Sweet specialtyLipstick is a fast, thick-walled pimiento with outstanding flavor (~53 days); Corno di Toro is a horn-shaped Italian frying pepper, excellent roasted (~68 days).
  • HotEarly Jalapeño is bred for northern gardens and reliable in short seasons (~65 days); Hungarian Wax is a productive medium-heat banana type that does well in cool summers (~65 days); Cayenne Long Red Slim is thin, tapered, prolific, and the best cayenne for drying (~75 days).

Short-season or cool-summer zones should lean on the early, cool-tolerant picks — Lipstick (~53 days), Early Jalapeño, Hungarian Wax — while long, warm zones can ripen the slower bells and cayenne with ease.

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
