Ancho peppers, known for their rich flavor and mild spice level, are an essential ingredient in various recipes, including sauces, stews, and traditional Mexican cuisine.
These dried, poblano peppers are not only versatile in the kitchen, but also relatively easy for gardeners to cultivate. Knowing when to harvest them ensures that you can fully enjoy the unique blend of sweetness and heat that these peppers have to offer.

To determine the best time to pick ancho peppers, gardeners must consider several factors, such as plant maturity, desired spiciness, and intended use.
The growth cycle of the poblano pepper is essential in assessing when they have reached the optimal stage for harvesting. Depending on the region and growing conditions, poblano peppers will typically take around 70 to 80 days from planting to full maturation.
Appearance and color also play a crucial role in judging when to pick ancho peppers. When they are ripe and ready for harvest, poblano peppers will be a glossy, dark green color, measuring approximately 4 to 6 inches in length. Though some individuals may choose to pick them early, allowing the peppers to age on the plant results in a deeper color and a more developed flavor profile.

Understanding ancho peppers
Ancho peppers are a popular variety of the Capsicum annuum species, known for their mild heat and sweet flavor profile. They are actually dried versions of the poblano pepper, which is a large, green, and slightly curved pepper variety. As poblano peppers mature, their color changes from green to red, and their flavor becomes even more complex.
The main difference between ancho and poblano peppers is the drying process. Anchos are poblano peppers that have been allowed to ripen fully, turning red before they are dried. Drying the peppers deepens their color to a dark reddish-brown and concentrates their flavors, creating a rich, sweet, and mildly spicy taste.
These versatile peppers are widely used in both Mexican and Tex-Mex cuisine, as well as many other dishes around the world. They can be rehydrated by soaking in hot water for a short time and used in sauces, stews, or soups, or ground into powder for use as a seasoning.
Ancho peppers are typically mild in heat, measuring between 1,000 and 1,500 Scoville Heat Units (SHU). This makes them a great option for those who enjoy the flavor of chiles but are sensitive to spiciness. The heat level can vary slightly depending on growing conditions and factors such as soil, climate, and even the age of the pepper.
To better understand when to pick ancho peppers, it’s essential to recognize the ripeness of the poblano pepper. Poblano peppers should be harvested when they have reached their full size and turned from green to red.
This indicates that they have reached their peak flavor and are ready to be dried and transformed into ancho peppers. To achieve the best flavor and texture of ancho peppers, let the poblanos mature and ripen fully on the plant before harvesting.

Growing ancho peppers
Soil and temperature requirements
Ancho peppers thrive in well-drained, fertile garden soil with a pH level between 6.0 and 6.5. To promote optimal growth, it’s best to ensure the soil maintains consistent warmth. Soil temperatures should be around 65 to 80°F (18 to 27°C) since peppers, including jalapeño, serrano, and heirloom varieties, are sensitive to cold and will grow poorly in cooler conditions.
When preparing your garden bed, consider amending the soil with organic matter, such as compost or well-aged manure, to improve its fertility. Adding a layer of mulch will also help to regulate soil temperature and conserve moisture.
Seeding and transplanting
Begin by starting your seeds indoors, approximately 8 to 10 weeks before the last expected frost date. Provide bottom heat by using a heating mat to maintain a consistent soil temperature of 75°F (24°C). Seeds should germinate within 10 to 14 days under these conditions.
Once seedlings have grown to a height of 2 to 3 inches, transplant them to larger pots to promote growth. When transplanting, it’s essential to harden them off by gradually exposing them to outdoor conditions. This process helps the young plants acclimate to their new environment and reduces the risk of shock.
When transplanting the seedlings to your outdoor garden, place them 18 to 24 inches apart to allow enough room for growth. Varieties such as the heirloom cubanelle pepper or hybrid ancho peppers may need additional space for their larger size.
It’s important to monitor and maintain your garden as the peppers grow. Regular watering, proper pruning, and consistent pest control will ensure a healthy, productive crop.
As the peppers ripen, you will notice a change in color – typically from dark green to red – signifying they are ready for harvest. Ancho peppers are usually picked when they are still green, relatively mild in heat, and before the capsaicin levels increase with further ripening.

Harvesting ancho peppers
When to harvest
Ancho peppers are best to harvest when they have reached their full size and developed a deep red color. This usually occurs a few months after planting, but the specific time may vary depending on the local growing conditions. To ensure a more successful harvest, it’s important to monitor the development of the peppers and check for the ripest ones periodically.
A useful harvesting guide for ancho peppers is to look for a consistent size among the crop, as well as a skin texture that is firm to the touch. Adhering to these indicators, will ensure that the peppers are at their peak flavor and nutritional content when harvested.
Harvesting tools
When it comes to harvesting ancho peppers, using the right tools can make the process more efficient and safe. Garden shears are highly recommended for cutting the stems of the peppers, as they provide a clean cut and minimize the risk of damaging the plant.
Additionally, wearing gloves during the harvesting process is essential for protecting your hands from any potential irritants. Some peppers, such as ancho peppers, contain capsaicin, which can be irritating if it comes into contact with your skin.
In summary, harvesting ancho peppers at the right time and with the proper tools will help ensure a successful and bountiful harvest. By following these guidelines, it will make the process smoother and more enjoyable for the gardener, while also providing quality ancho peppers for consumption.
Storing ancho peppers
When it comes to storing ancho peppers, understanding the proper methods helps prolong their shelf life and preserve their flavor. The following are the most effective ways to store ancho peppers.
Airtight container storage
Storing ancho peppers in an airtight container is an excellent method to keep them fresh and maintain their quality. It is essential to ensure that the storage area is cool, dark, and dry to prevent the ancho peppers from becoming brittle. Place the peppers inside a glass or plastic airtight container and securely seal the lid.
- Cool and dark place: An ideal location would be a pantry or cupboard, away from direct sunlight and heat sources.
- Dry environment: It is important to keep ancho peppers dry, as moisture can cause mold growth and decrease their shelf life.
Using an airtight container for storage will help retain the ancho peppers’ flavor and aroma while prolonging their shelf life for up to 12 months.
Freezing method
Freezing ancho peppers is a viable option for long-term storage. This method preserves their flavor and texture, making them suitable for future use in various recipes.
