Organic Poblano Pepper Seeds
Poblano pepper seeds produce heart-shaped fruits that ripen from dark green to deep red and are called Ancho when dried and Poblano when fresh. One of the most popular peppers grown in Mexico! Growers can choose between harvesting fully ripened, red fruits, which are much hotter and more flavorful, or green fruit picked earlier.

Planting by Zones
- Peppers are a warm-season crop in Zones 9 and 10. You can plant them in the spring through late summer. Many pepper plants can perennialize in Zones 9 and 10, but their production will diminish drastically.
- Start inside 8 weeks prior to the last frost. Use a heating pad to ensure good germination rates.
Planting Poblano Pepper Seeds
- In Zones 9 and 10, you can direct seed or transplant out your pepper seeds. We recommend you start them in early spring in starter pots and transplant them out.
- Peppers need warm soil to germinate. If you are starting them in starter pots, a heating pad will speed up the germination process. If you are planting outside, make sure the soil is at least 80°F (26°C).
- To direct sow, plant seeds in debris-free, well-worked soil that has been deeply watered. Cover with 1/4″ (.6cm) of finely sifted soil. The minimum temperatures at night should be no less than 60°F (15°C).
- If you are planting seeds in starter pots, plant seeds into thoroughly moist high-quality seed starting soil. Place seeds on the top of the soil and cover with 1/4″ (.6cm) of finely sifted soil.
- Once your seeds have germinated and are 1-2″ (2.5-5.5cm) tall, fertilize with an organic liquid fertilizer. When the plants are 3-4″ (7.6-10.2cm) tall you can plant them out into the garden.
- Space plants at least 12″ (30.5cm) apart.
Growing Poblano Peppers
- Peppers are easy to grow once you get them established.
- Mulching heavily around your peppers will help with weed suppression and moisture retention.
Harvesting Poblano Peppers
- Harvest peppers often to encourage more production. Cut fruits from their stems; do not pull.
Growing Peppers in Containers
- Peppers make excellent container plants. Make sure your container is at least 20″ (50.8cm) deep and provide support for the plants to grow up. Keep in mind containers will dry out faster because they have more surface area and less soil to hold onto moisture. Mulch heavily on the top layer of soil in the pot to keep the soil from drying out or heating up too much.
Southern California Pro Tips
- Mulch heavily around your plants to ensure the soil does not dry out or heat up too much.
- When growing bell peppers, shade cloth can help to diminish sunscald that can scar the skin of the peppers.
- Interplanting flowers with your peppers will make your garden beautiful and reduce pest issues. Marigolds look stunning when interplanted with pepper plants. You can also grow zinnias, cosmos, and cornflowers.
