How to Plant, Grow, and Care for Shishito Peppers

Mild, wrinkled, and incredibly flavorful, ‘Shishito’ peppers are growing into mainstays of American cuisine. One specimen produces dozens of wrinkly chile peppers on a compact plant, making it a perfect choice for gardens big and small. Learn how to nurture....

this variety alongside seasoned pepper gardener Jerad Bryant.

When you bite into a blistered ‘Shishito’ pepper with salt and pepper, there is a chance it surprises you with slight spiciness! Most ‘Shishito’ peppers will be very mild, from 0 to 200 Scoville units; occasionally, a fruit sprouts with the heat of a mild jalapeño.

The first time I tried this variety, I didn’t believe some of the fruits could be mild, while a few contained considerable heat! After eating a dozen, though, I bit into one of the spicy ones. It filled my mouth with a warm sensation, and I quickly reached for my water glass; to my surprise, the spiciness faded quickly. Before I knew it, I was popping more ‘Shishito’ chiles in my mouth.

Use them as you would any other variety—they are versatile in the kitchen. ‘Shishitos’ are one of the most flavorful specimens. They taste decadently fresh, especially when you blister them in olive oil with salt and pepper. This variety mixes well in salsa, soups, and stews; the mild flavor lends well to fermented goods.
What Is It?

The ‘Shishito’ variety is a descendant of Capsicum annuum species from the Americas. Portuguese traders hauled peppers to Japan, where they traded them for other goods. Growers in Japan then took them, bred them, and created unique varieties that have since spread across the globe. ‘Shishito’ is one of them.

Native Area
Although the Capsicum annuum species are originally native to the Americas, ‘Shishito’ first sprouted in Japan. It prefers warm, hot summers with lots of direct sunlight and airflow. Japan is a maritime country, and its proximity to the ocean leads to lots of moisture falling on the land. This excess moisture hydrates ‘Shishito’ plants while they bask in the sun.

Characteristics
Like other species of Capsicum annuum, ‘Shishito’ blooms white star-shaped blossoms. These are bisexual or “perfect” flowers, and they are self-pollinating. Peppers, like eggplants and tomatoes, prefer to cross-pollinate with other plants—they self-pollinate when there are no other partners to mingle with.

‘Shishito’ plants are nice and compact, reaching maximum heights of two to three feet in maturity. Although they look like cute little adults, they produce fruits as if they’re ten feet tall! One plant creates dozens of chiles during its lifetime.

‘Shishito’ fruits elongate to two to four inches long. They’re tastiest when green and have slightly wrinkled yellow-green skin that ripens red. Red fruits are edible, although they lack the satisfying crunch of the green ones. Pick both and try them yourself to see which you prefer!

Planting
Due to their compact nature, ‘Shishito’ plants thrive in containers and raised beds. They tuck in neatly under taller plants and flourish in most garden settings. Choose a spot in full sun with occasional airflow. They appreciate moist, fertile soil—when the ground is loose loam, their roots creep deep below the surface and anchor the plant.

Amend clay or sandy soil with a healthy helping of compost or a similar organic amendment. Compost inoculates the dirt with bacteria, fungi, and critters like worms and bugs. Over time, consistent doses transform sandy or clay soil into humus-rich loam.
How to Grow
As garden plants, ‘Shishito’ develops similarly to eggplants; they’re upright and bushy, and they appreciate staking or caging for support. Offer them full sun, fertile loam, and ample water, and they’ll reward you with abundant harvests from summer through autumn.
Maintenance

‘Shishito’ needs little maintenance. It enjoys growing up a stake, trellis, or cage, as it appreciates the extra support.

This type may benefit from pruning if it is overly bushy or sprouts crowded growth. The leaves up top shade out the fruits and flowers below. Prune a few top leaves as needed to allow sunlight to reach fruits on the interior. Cut less than one-third off at any time to avoid shocking the plant.

Near the end of the growing season, fall frost approaches and threatens the fruit ripening process. Cover plants on cold nights with a cold frame or similar structure, and hard-prune them. Hard pruning convinces the cultivars to redirect their energy towards fruit ripening—to do this, cut all stems above ripening fruit and remove a third of the leaves. Pinch off new growth like flowers, leaves, and sprouts.
