Bell pepper plants should generally be planted about 18 inches apart from stem to stem to allow adequate room for growth, air circulation, and nutrient uptake
. Rows of bell peppers are typically spaced 24 to 36 inches apart to provide enough space for access and airflow between rows
. Key points on bell pepper spacing:
- Between plants: 18 inches apart is the common recommendation, balancing plant health and space efficiency
- Between rows: 24 to 36 inches apart, depending on garden layout and access needs
- Planting pattern: Staggering plants in a triangular or grid pattern can maximize space and improve air circulation
- Why spacing matters: Proper spacing reduces disease and pest problems by improving airflow and prevents plants from competing excessively for nutrients and light
Some sources note that while 18 inches is standard, bell pepper plants can spread 18 to 24 inches wide, so spacing closer than 18 inches may cause crowding and increase disease risk
. If space allows, increasing spacing slightly to 24 inches can improve plant health and yield. In summary, plant bell peppers about 18 inches apart within rows, with 24 to 36 inches between rows, and consider staggering plants to optimize growth and harvest
