Grow Capsicum annuum 'Sweet Banana' when you want a steady supply of mild, banana-shaped peppers that start pale yellow and can ripen through orange to red. This warm-season vegetable forms a compact, upright plant that typically reaches about 24-30 inches tall with a spread around 15-18 inches, making it a good fit for beds, raised gardens, and larger patio containers.
Plant after all danger of frost has passed and nights are consistently warm. Give it full sun for best flowering and fruit set. In hotter areas, you can still aim for full sun, but keeping the soil evenly moist helps reduce stress and improves yield.
Provide fertile, well-drained soil and water deeply when the top inch of soil dries. A layer of mulch helps stabilize moisture and temperature. Stake or cage plants if they become heavy with fruit, and avoid excessive nitrogen, which can encourage leaves at the expense of peppers.
Harvest fruits at the pale yellow stage for a sweet, crisp flavor, or leave them longer to deepen color and sweetness. Regular picking encourages continued production through the warm months.
