When To Harvest Serrano Peppers [Tips on Harvesting]

Growing and harvesting can be a very rewarding and fun activity for those who love to garden. To get the best yield from your Serrano Pepper plants, you should know some basics about harvesting serrano peppers. This article covers the details on when to harvest serrano peppers.

Serrano Peppers should be harvested when they are still green and unripe. If left on the plant too long, they will turn red and become too soft to use. Some people pick them even when they are slightly yellow, but this is not recommended by most experts.

The best time to pick serrano peppers is in the morning after the dew has dried, but before it gets too hot. You can also harvest serrano peppers in mid-afternoon if you will be preparing them right away.

Serrano peppers are an excellent source of vitamin A and C, as well as dietary fiber. Both serrano peppers and jalapeno peppers are hot, but serrano pepper plants are smaller which makes them ideal for container gardening. Serrano pepper plants grow very well with basil or Mexican tarragon.

What is a Serrano pepper?

Serrano is a chili pepper that originated in the mountainous regions of the Mexican states of Puebla and Hidalgo. It is known as piquin in Mexico, and chile seco del norte or just chile norte in California. It is about 2–5 cm long and tapers to a blunt point; it may be straight or slightly curved. The chilies ripen from green to red, but some varieties of the plant produce chilies that mature to yellowish-orange hues.

Many people refer to serranos as “bird’s beak chilies” in English or “chile de agua” in Spanish because of their tapering shape and sharp point. Serranos are an important ingredient in Mexican cuisine, especially in dishes such as tamales, menudo, salsas, and guacamole.

 Harvesting Serrano pepper

The Serrano chili is related to the cayenne pepper which originated in French Guiana, and the African bird’s eye chili. Serrano pepper plants are between 30-90 cm tall and can grow up to 1 meter if unpruned. They have green stems with 4–7 branches at each node, 7 to 15 cm long leaves, and small white flowers with yellow stamens developing from light green flower buds. After a few weeks, small green berries begin to form on the plant. As they ripen, the green color changes to a bright red that remains for several months even when the temperatures drop below freezing.

From June through August, serrano pepper plants can produce up to 100 peppers from each fruit bunch. A single plant will produce just 20-30 peppers per year, but they are prolific growers and may require staking to keep them upright.

Serrano pepper plants must be grown under natural sunlight to produce fruit with the proper color and flavor. Cloudy days completely alter the growth cycle of the plant.

Serrano peppers are ready for harvest when the fruit has reached full maturity and is completely red. The time needed to reach maturity varies greatly depending on temperature, sunlight, water availability, and soil composition. Serranos left unpicked will fall from the plant when fully ripe to help future crops grow more easily.


Serrano peppers are small, slender chilies that start green and gradually ripen into the red. Handle with care when harvesting to avoid irritation from the chili’s capsaicin oil [the chemical that makes chilies hot]. To harvest, carefully cut or pull serrano peppers from the plant. Avoid touching the chili with bare hands.

For the best flavor, serrano peppers should be harvested while still green [the hotter-tasting chilies come from red or orange peppers].

However, if ripe fruit is desired for decoration or other purposes, pick serrano peppers when they’ve turned red. Be careful though, because this will cause them to be much hotter.

The stems, leaves, and fruit of the serrano pepper plant are all covered in fine hairs [similar to a fuzz], which cause the unpleasant “burn” associated with chili peppers. If you do accidentally touch any part of this plant, wash your hands thoroughly with soap and water to avoid irritation.
