Poblano Peppers (also called Ancho Chile Peppers) are classic large dark-green hot peppers, originating from Puebla, Mexico. These Mexican peppers pair well with smokey flavors and roast well. Known for their mild heat and earthy taste, poblanos are ideal for creating dishes like chile rellenos, a traditional Mexican dish, and are dried & smoked to make Mulato, or ground into chile powder and mole sauces. Serve ancho chilies roasted and peeled, whole or diced, and smothered in sauces. These classic peppers also pack a flavorful punch in salsas and hot sauces, and lend well to drying or dehydration. The plants are prolific and easy to grow, providing an abundant harvest of these culinary treasures. Whether you're a seasoned chef or a home gardener, you'll love the opportunity to elevate your dishes with the complex, smoky flavor of fresh poblanos. Spice level is low (1,000 to 2,000 Scoville Units). Also Known As: Puebla Pepper, Mexican Chili Pepper, Rilleno/Relleno Pepper, Ancho Chilies, Ancho Pepper, Pasilla Bajio, Chile Poblano, Padrón Pepper, Poblano Chile, Mulato, Guajillo, Chile Ancho Poblano.

Planting Instructions: Soil Preparation: Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 8-12 inches deep. Loosening the soil will help the plant establish strong roots. Plants grow best in soil with lots of organic matter. You may optionally add fertilizer or organic material such as compost, leaves, or rotted hay to mix into the soil at this point. For small gardens, scatter 2-3 tablespoons of a complete fertilizer evenly and work into the top 2-3 inches of soil for each hill or 2 foot by 2 foot planting area. For larger gardens, scatter 2-3 pounds of a complete fertilizer for each 100 square feet of planting area. Work fertilizer or organic material into the soil and leave the surface smooth. Form rows of soil beds 4-6 inches high and at least 3 feet apart. This formation of ridges will help with drainage. Planting: Peppers grows best in warm weather, with ideal temperatures of between 65F-80F during the day and nighttime temperatures of between 60F-70F. Starting Indoors: For an earlier pepper harvest, you may optionally start planting indoors in containers 8-10 weeks before the last expected frost date in Spring, keeping seedlings at least 70F. Harden off then transplant seedlings outdoors in a sunny location when the soil temperature is above 65F. To transplant seedlings, prepare a transplant hole outdoors in a sunny location. Remove the plants carefully from the pots or flats and set them in the holes, burying some of the stem in the ground. Pack the soil loosely around the plant and leave a slightly sunken area around each plant to hold water. Water the plants after transplanting. Directly Sowing: If directly sowing peppers outdoors, plant peppers in late spring when the soil warms to at least 65F. Fall planting is not typically recommended since they require heat and a long growing season but is possible in climates with mild winters, with consistent 70-80F conditions, or if growing indoors >70F and using supplemental grow lights. If Fall planting, plant at least 12-16 weeks before the first expected frost in Fall. To plant, make holes 1/2 inch deep and spaced 18 inches apart down the rows of raised beds. Plant 2-3 seeds per hole. If choosing to thin to the strongest plant, determine the strongest and healthiest plant, then remove all other plants, narrowing to a single plant per hole. Cover seeds thinly with soil and water after planting. Planting Depth: 1/2 inch Within-Row Spacing: 18 inches Between-Row Spacing: 3 feet Care During the Season: Watering: Water the plants deeply, soaking the soil to a depth of 6-8 inches, once to twice a week. If there is no rainfall, water 3-4 times a week. Sandy soils may need to be watered more often than heavy clay soils. Mulching around plants can help retain moisture. Weeding: Keeping plants weed-free improves production. If plowing or hoeing, do not dig deeper than 1 inch to prevent from cutting the feeder roots. Fertilizing: Once seedlings are established, 2-3 weeks after germination, you may optionally apply 2 tablespoons of a complete fertilizer around each hole, or 1-2 pounds per 100 square feet, without letting the fertilizer touch the plants. Optionally, continue fertilizing every 1-2 weeks as plants grow. Water plants after fertilizing. Insecticides: Insecticides may be used to protect plants. Bt-based insecticides and sulfur are organic options that can be used for prevention. Sulfur also has fungicidal properties and helps in controlling many diseases. Before using a pesticide, read the label and follow cautions, warnings and directions. Diseases: If spots or mold appear, treat plants with an approved fungicide. Neem oil, sulfur, and other fungicides may be used. When using fungicides always follow label directions. Harvesting: Poblano Peppers can be harvested when they are firm, glossy, are 4 to 6 inches long and slightly tapered, about 65 to 80 days after planting. Poblano peppers can be harvested while they are dark green for a mild, earthy flavor, or you can allow them to ripen on the plant until they turn red, which gives them a sweeter and more complex taste. To harvest, use clean scissors or pruning shears to cut the peppers from the plant, leaving a small portion of the stem attached to avoid damaging the plant. Avoid pulling the peppers by hand, as this can harm the plant. Regular harvesting encourages the plant to continue producing more fruit throughout the growing season.
