Soil, care & harvest
Prepare your soil to a pH between 6.0 and 6.8 before sowing. Since 'Cubanelle' is a frost-sensitive warm-season crop, you must start seeds indoors only after the last spring frost date or wait until soil temperatures are consistently warm. Sow seeds at a depth of roughly one-quarter inch; they typically germinate within 10 to 14 days.
Space plants 18 to 20 inches apart in full sun, ensuring they receive at least six hours of light daily. Water regularly to maintain even moisture, aiming for 1 to 1.5 inches per week. Apply mulch around the base to retain soil warmth and feed the plants with balanced fertilizer as they develop.
Watch for aphids, pepper weevil, European corn borer, and flea beetles; inspect leaves frequently and remove infested parts early. Prevent fungal issues like bacterial spot by avoiding overhead watering. Harvest the fruit 60 to 70 days after planting when they reach full color and size.
