In addition to winterization pruning, early- and late-season pruning will help growth. While the plants are establishing in the spring, remove diseased leaves, lower branches and side shoots so the main stems grow stronger. Then 3-4 weeks before the first fall frost, cut away branches and flowers without fruit so the remaining fruit has more resources.
A bell pepper is ready to harvest when it is your preferred color (green, yellow, red, orange), is firm and has a light sheen. Use a knife, shears or sharp scissors to cut the fruit at the stem. Harvesting regularly will spur the plant to produce more fruit. Bell peppers last 1-2 weeks in the refrigerator.
