Perilla, also known as shiso or beefsteak plant, is an aromatic herb that belongs to the mint family. Its unique flavor and versatility in culinary dishes have made it increasingly popular among gardeners and chefs alike. If you’re in Minnesota and want to grow this flavorful herb, understanding its specific requirements is essential for successful cultivation. This article will guide you through the process of growing perilla in Minnesota, from choosing the right variety to harvesting your crop.
Perilla (Perilla frutescens) is a fast-growing annual herb native to East Asia. It is characterized by its distinctive leaves, which can vary in color from green to purple. The plant can reach heights of 12 to 36 inches and produces small flowers that attract pollinators. Perilla is not only prized for its culinary uses but also for its ornamental value in gardens.
There are two main varieties of perilla:
In Minnesota, both varieties can be grown successfully if proper care and attention are given.
Perilla thrives in full sun, requiring at least 6 hours of direct sunlight each day. Choose a location in your garden that receives ample sunlight throughout the day. If you live in a region with particularly hot summers, some afternoon shade can help prevent the leaves from scorching.
Perilla prefers well-draining soil rich in organic matter. The ideal soil pH for growing perilla ranges from 6.0 to 7.0. Conduct a soil test to determine your soil’s pH and amend it if necessary with compost or organic fertilizers to enhance fertility.
When planting perilla, ensure there is adequate space between plants to allow air circulation and promote healthy growth. Plants should be spaced about 12 to 18 inches apart.
In Minnesota, the growing season can be short due to colder temperatures and frost risk. The best time to plant perilla seeds or transplants is after the last frost date, typically around mid to late May. You can start seeds indoors about 4–6 weeks before the last frost date if you want an earlier harvest.
If you choose to start perilla seeds indoors, follow these steps:
Once seedlings have developed several sets of true leaves and outdoor temperatures are consistently above 60°F, they’re ready to be transplanted into the garden:
Maintaining consistent moisture is crucial for healthy perilla growth. Water regularly but avoid overwatering, as soggy soil can lead to root rot. A deep watering once a week should suffice unless there’s heavy rainfall.
To encourage lush growth, apply a balanced organic fertilizer every few weeks during the growing season. Avoid high-nitrogen fertilizers, as they may lead to excessive leaf growth at the expense of flavor development.
While perilla is relatively pest-resistant, keep an eye out for common garden pests such as aphids and spider mites. If you notice any infestations:
Regular pruning helps maintain plant health and promotes bushier growth. Pinch back tips of the stems when they reach about 6 inches tall; this encourages branching and increases leaf production.
One of the joys of growing perilla is reaping its flavorful harvests throughout the summer months.
You can start harvesting perilla leaves once they are large enough—usually about 4–6 inches long—typically around 4–6 weeks after transplanting outdoors. Leaves can be picked individually or whole branches can be cut back.
Use clean scissors or garden shears to snip off leaves or branches carefully without damaging the plant itself. Always leave some foliage behind so that the plant can continue producing throughout the growing season.
Perilla’s unique flavor profile makes it versatile in various culinary applications:
As an annual herb, perilla will not survive Minnesota winters; however, you can collect seeds from mature plants before the first frost if you wish to grow more next season:
Growing perilla in Minnesota can be a rewarding experience both in terms of aesthetics and culinary delight. By following these guidelines on planting, caring for, harvesting, and utilizing this aromatic herb, you will be well-equipped to enjoy fresh perilla throughout your growing season—and perhaps even have enough left over for future planting! With its unique flavor profile and versatility in cooking, your kitchen will thank you for adding this delightful herb to your repertoire. Happy gardening!
