To grow green peppers, select a variety suitable for your climate and start the seeds indoors 7 to 10 weeks before transplanting. Plant them outdoors in a trench 2 to 3 weeks after the last frost, ensuring they are in full sun with rich soil, and water regularly to maintain moist conditions. Peppers should be allowed to grow to 7.6 to 10.2 cm before harvesting, which takes about 50 to 70 days after transplanting, using row covers if temperatures drop.
