Ease of Cultivation and Culinary Use: Korean Shiso, also known as Perilla, is a flavorful herb with broad, serrated leaves that have a distinct aroma and taste. This herb is relatively easy to grow, thriving in well-drained soil and preferring full sun to partial shade. It is a staple in Korean cuisine, commonly used in salads, as a wrap for meats, and in soups, adding a unique, minty flavor that enhances a variety of dishes.

Direct Sowing: For direct sowing, plant Korean Shiso seeds outdoors in the spring after the last frost. Sow the seeds about ¼ inch deep and space them 12-18 inches apart to accommodate their spread. Germination usually occurs within 7–14 days, so it’s essential to keep the soil consistently moist during this period. Ensure the plants receive adequate sunlight to promote healthy growth and vibrant leaves.

Early Sowing for Seedlings: To start early, sow Korean Shiso seeds indoors 6–8 weeks before the last expected frost. Use seedling trays filled with quality potting mix, covering the seeds lightly with soil. Maintain a temperature around 70°F for optimal germination. Once the seedlings have developed several true leaves and the risk of frost has passed, transplant them outdoors, ensuring sufficient spacing for robust growth.

Harvesting: To determine when Korean Shiso is ready for harvest, look for healthy plants with lush green leaves, typically within 60-90 days of planting. You can begin harvesting once the leaves are fully formed and vibrant. The best time to harvest is in the morning after the dew has dried, as this is when the essential oils are most concentrated. Regular harvesting encourages bushier growth and ensures a steady supply of flavorful leaves throughout the growing season.
