🌾 Sow directly in the garden — Poblano 'Mulato Isleno' is not usually started indoors.
Do not direct sow until soil is warm; instead, start seeds indoors several weeks before the last frost and transplant seedlings outside only after all danger of frost has passed.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.2 and 7.0. As a warm-season crop, start seeds indoors 8-10 weeks before the last frost date. Sow seeds about 1/4 inch deep; they typically germinate within 14 to 21 days once soil temperatures are consistently warm.
Space plants 24 to 30 inches apart in full sun. Provide consistent moisture, aiming for 1 to 1.5 inches per week with deep watering. Apply organic mulch around the base to retain moisture and feed the soil regularly during the active growing season to support heavy fruit production.
Watch for aphids, spider mites, pepper weevil, and thrips by inspecting leaves frequently. Prevent bacterial spot, phytophthora blight, and verticillium wilt through good air circulation and avoiding overhead watering. Harvest the pods 75 to 85 days after planting when they reach their full dark color.
