Where and when to grow banana peppers
Banana pepper seeds take about 14 days to germinate. Transplant pepper seedlings 40 days after germination. Wait until well after the last frost before moving seedlings outdoors. Note that even a light frost can cause serious damage. Soil temperatures should be at least 70 degrees Fahrenheit in the daytime and above 60 degrees at night. Transplant them into soil that has been enriched with compost. Note that while banana peppers prefer hot weather, temperatures above 90 degrees can cause them to lose blossoms. Losing blossoms causes the plants to produce fewer fruit. You should plant sweet and hot varieties as far from each other as possible to prevent cross-pollination.
Feeding and watering banana peppers
The soil should be kept consistently moist. A soaker hose is useful for providing consistency when watering. Use mulch after transplanting to help the soil retain moisture and to keep weeds from sprouting. Once peppers start to develop, use a fertilizer that is rich in phosphorous and potassium. Note that fertilizers with a high nitrogen content can increase foliage but are not beneficial for producing fruit. When fertilizing your banana peppers, use the side dressing method. Side dressing is the application of fertilizer to the soil around the plant. Spray your plants with a solution of Epsom salts and water occasionally if your soil is magnesium deficient.
Harvesting banana peppers
Pick banana peppers regularly as this will encourage the plant to keep producing. Use a sharp knife or scissors to cut stems rather than pulling peppers from the plant. Simply pulling peppers off can damage branches.
Banana pepper plant care
Banana peppers can sometimes fall prey to aphid infestations. You can get rid of aphids with insecticidal soap or by spraying them off with a hose. Manually remove any beetles or caterpillars.
Avoid blossom end rot by watering your pepper plants consistently; a soaker hose can help with this. Note that a soaker hose can also help to prevent fungal and bacterial diseases that arise because of over watering and overhead watering.
