How to Grow Chili Peppers from Seeds

Growing chili peppers from seeds is both enjoyable and simple! Plant the seeds in a warm, consistent environment, then place the sprouted seeds into light compost to nurture them into seedlings. Carefully transfer the seedlings into small pots, keeping them warm and ensuring they get enough water. When the plants grow larger or when the weather warms up, transfer them to bigger pots or plant them outdoors. Don't forget to occasionally harvest the peppers for seasoning your meals!

Place the chili seeds between two layers of damp paper towels. Wet two pieces of paper towels, scatter the chili seeds on one sheet, and cover them with the other. Then, put them in a resealable plastic bag or a plastic box and seal it shut.

Place the chili seeds in a warm spot for 2-5 days. In general, chili seeds require a temperature range of 23-30°C to sprout. Set the seed container in a place with a stable warm temperature (such as on a heating mat) for 2-5 days until the seeds germinate. Make sure the temperature is not hot enough to soften the plastic bag containing the seeds.

• Pre-sprouting the seeds before planting them in soil or compost increases the chances of successful germination.
• In warmer climates, you can sow seeds outdoors for germination as long as the temperature does not drop below 15°C.

Fill the seedling tray with soil. Add planting soil or compost to a wide seed tray or a tray with multiple sections until it reaches the top. Break up any large clumps of soil. Press the surface down 1-2 mm and water lightly.

• Water just before sowing the seeds, and only water very sparingly after that until the seeds begin to sprout.

Sprinkle the seeds and cover with soil. Scatter each chili seed on the surface of the soil, spaced about 5 cm apart. Cover them with a thin layer of soil. Lightly press the soil down and spray water on the surface of the soil using a sprayer.

Cover the tray and wait for the seeds to sprout. Use plastic wrap to seal the tray to retain heat and moisture. Place the tray in the same spot where you sowed the seeds earlier. If desired, you can purchase an electric heating mat or seed tray (available in garden stores) to maintain a stable temperature for the seedlings.

Monitor the seedlings. Keep an eye on the seedling tray to observe the germination process and ensure the soil quality. The soil must remain moist but not soggy. Do not water unless the soil becomes too dry. The plants should begin to sprout after about two weeks.

Gently remove the seedlings from the tray. When the chili seedlings reach about 5 cm in height and have 5-6 leaves, it's time to move them to a larger space to prevent root crowding. Carefully lift the seedlings from the tray, being careful not to disturb the roots too much.

• Water the seedlings before removing them to prevent the soil from falling apart during the transfer.

Plant each seedling into a separate pot. Fill a pot with soil, around 7 cm in diameter. Water the soil to keep it moist, then dig a hole in the center of the pot. Gently place the seedling in the hole and cover it with soil.

• If you live in a cooler climate, plant the chili in a pot and keep it indoors. Place the plant under a grow light in a warm room.
• You can transplant the plant from the pot into the garden when the weather and soil are warm enough.

Transfer the plant to a larger pot if necessary. As the chili plant grows, it’s important to move it to a larger pot. Fill the new pot with soil, then dig a hole in the center. Gently lift the plant with its root ball and place it into the new pot.

• If you want the plant to stay small, leave it in a smaller pot to slow down its growth.
• The pot sizes can increase from 7 cm to 15 cm, and eventually to a 20 cm pot.

Ensure the plant gets enough light and moisture. Place the chili pot near a window or outside so the plant can receive sunlight, but bring it indoors if the temperature drops. The amount of light the plant receives will impact its growth rate and size.

• If you're growing the plant indoors with limited natural light, consider purchasing a mini greenhouse or grow lights (available online or at garden centers).

Plant the chili. Choose a sunny spot in the garden that receives at least 6-8 hours of sunlight per day and dig a hole big enough for the plant. Use a garden fork to loosen some soil at the bottom of the hole, then add a handful of compost. Gently place the plant into the hole, then cover it with a mix of soil and compost.

• Space the chili plants at least 45 cm apart from other plants to give them enough room to grow.

Water and fertilize the plant regularly. In hot climates, water the chili plant daily to keep it hydrated. Be careful not to overwater; the soil should be moist but not waterlogged. Fertilize the plant every two weeks using liquid all-purpose fertilizer (available at garden centers).

Keep the plant warm. Only plant chili outdoors in regions with a warm climate year-round or areas with a long summer. In the latter case, it’s best to plant in June. Consider purchasing fleece or plant cloches (dome-shaped covers placed over the plant and anchored into the ground) to protect the plant when the weather unexpectedly turns cold.

• Harvest the chili regularly to encourage continuous fruiting and prevent the plant from falling over due to the weight of the fruit.
• Stake the plant as soon as it starts to lean to prevent it from toppling over.
• Before transplanting the chili into the garden, acclimate the plant to the outdoors by leaving it outside for a few hours each day for about two weeks.
