Sowing and Growing

Shiso prefers full sun and grows best in moist, rich soil. Although a warm weather lover, shiso also does well in partial shade. Sow seeds indoors about 6 weeks before the last frost date. Germination takes up to 2 weeks. Plant outside when young plants have 4 to 6 true leaves. Growing shiso is often compared to basil in terms of growing. Pinch tips for a bushy plant and remove flowers to delay the end of its life cycle.


Once shiso plants are established, harvest leaves for fresh use as needed. The uses of shiso are numerous because of its unique zesty flavor. Add to salads, asian dishes or use in sushi. Try shiso as a substitute for basil in pesto. Incorporate into brew tea for added zing! The red/purple variety can be used to color pickling brine. The unopened flower spikes can also be fried, and are often used to make dyes.
