Peppers are heavy feeders and will quickly become leggy and top-heavy if not supported. Stakes should be placed around the perimeter of the planting bed, about 18 inches apart.

Use tomato cages or similar supports that can be easily removed when it comes time to harvest the Peppers.

Pests and Diseases of Serrano Peppers and Their Control

Common pests are aphids, whiteflies, and spider mites. Aphids suck the sap from plants. They are usually green or black and can be found on the undersides of leaves. Whiteflies are small, white insects that fly around plants and feed on the sap. They can be controlled with sticky traps or by using an insecticide. Spider mites are small, red spiders that spin webs on the undersides of leaves. They can be controlled with horticultural oil or insecticide.

Several diseases can affect Serrano Peppers, but luckily, there are also ways to control them. Blossom-end rot is a disease that affects fruits and vegetables, and it’s caused by a lack of calcium in the plant. The symptoms include brown or black spots on the bottom of the fruit. To prevent this disease, fertilize your plants with calcium-rich fertilizer.

Powdery mildew disease affects many different types of plants, and white or gray powdery spots on the leaves characterize it. To prevent powdery mildew, water your plants early in the day. You can use a fungicide to treat powdery mildew if it does occur. Bacterial leaf spot is caused by bacteria that results in dark brown or black spots on the leaves. A yellow halo may also surround the spots. Bacterial leaf spot can be prevented by planting resistant varieties of Serrano Peppers and avoiding overhead watering.

Harvesting Serrano Peppers

To harvest your Serrano Peppers, wait until they are deep green and have reached their full size. You can then pick them by hand or cut them off the plant with pruning shears. Be sure to wear gloves when handling the Peppers, as they can be quite spicy. If you want to dry or dehydrate your Serrano Peppers, hang them upside down in a well-ventilated area. Once dried, you can store them in an airtight container for up to 6 months.
