Bell peppers (Capsicum annuum) are one of the most colorful vegetables you can grow. They come in many shades, including green, red, yellow, orange, and even purple or white. The plants stay fairly small, with big leaves and white flowers that turn into peppers of different sizes—from tiny minis to large, blocky fruits.
Starting bell peppers from seeds is fun and rewarding for beginners and experienced gardeners. You get access to more types than what stores usually sell, and it often costs less than buying young plants. With the right care, your pepper plants will produce lots of tasty fruit all season long.
This guide explains each step for growing bell peppers successfully—from seed to harvest.
Pick Your Seeds Wisely
Begin with high-quality seeds from a trusted seller. You can find them online or at a garden store. Choose the type that interests you—classic bell peppers, sweet varieties, or mini snack-sized peppers. You can even start several kinds at once to see which you like best.
Start Them Indoors
Bell peppers need warmth to sprout, so it’s best to start seeds inside. Begin planting 8–10 weeks before your area’s last frost date. Use small pots or seed trays with drainage holes and fill them with seed-starting mix. Plant each seed about 1/4 inch deep and place the tray in a warm, bright area.
Keep It Warm and Light
Pepper seeds sprout fastest when the soil stays between 70°F and 80°F (21°C–27°C). If you do not have a sunny window, use a grow light and keep it on for 14–16 hours a day. A heating mat under the tray can help keep the soil evenly warm and speed up germination.
Watering Is Key
Keep the soil lightly moist, but avoid soaking it. Covering the pots with plastic wrap helps trap moisture until seedlings appear. After they sprout, remove the cover and continue watering so the soil stays damp but not soggy.
Transplant with Care
When seedlings have 2–3 sets of real leaves, they are ready to move outdoors. First, harden them off by placing them outside for a few hours each day. Start in a shady area and slowly expose them to more sun and outdoor temperatures over about a week.
Choose the Right Spot
Bell peppers love sunlight. Pick a garden area that gets 6–8 hours of direct light per day. The soil should drain well and be rich in nutrients. Mixing compost or aged manure into the soil before planting helps give your young plants a strong start.
Support Your Plants
As peppers grow, the branches can bend under the weight of developing fruit. Use stakes, tomato cages, or simple homemade supports to help the plant stand upright. This also improves airflow around the leaves, helping prevent disease.
Harvest Time
Most bell peppers are ready to pick 60–90 days after planting in the garden. You can harvest them when they are full-sized and green, or wait until they turn red, yellow, orange, or another final color—the longer they stay on the plant, the sweeter they become. Cut peppers off with scissors or a knife, and start enjoying your homegrown harvest!
