Bring big harvests to your garden with Capsicum annuum 'Big Bertha', a sweet bell pepper grown for extra-large, blocky fruit with thick walls and mild flavor. You will get the best production when you give it warm weather, rich soil, and steady moisture. Plants typically stay compact at about 12-24 inches tall, making them a great fit for raised beds and large containers.
Start seeds indoors 8-10 weeks before your last frost, or plant starts after nights are reliably warm. Choose a spot with full sun; in very hot climates, light afternoon shade can help reduce stress. Set transplants so the root ball sits at the same depth as in the pot, and space plants to allow good airflow. Work compost into the soil, then water deeply after planting and keep the soil evenly moist through flowering and fruit set.
Feed lightly but consistently, avoid heavy nitrogen once buds form, and use a stake or small cage if fruit load becomes heavy. Harvest peppers green for earlier use or leave them longer to fully size and color. Remove ripe fruit regularly to keep the plant producing. In frost-free climates, you can often keep plants going for multiple seasons by protecting them from cold and giving them a bright, sheltered spot.
