Sow outside 1-2 weeks after average last frost and when temperatures are warm. Start indoors 4 weeks before average last frost. Gently press seeds into soil, but do not cover as they require light to germinate. Freezing seeds for several days before sowing improves germination.
When sowing indoors, germination rates are sometimes lower, even in optimal conditions. Freezing seeds for several days before sowing improves germination.
Shiso is easy to grow and can be treated much like basil.
Shiso is a "cut and come again" plant, so it can be harvested more than once a season by cutting high enough to allow grow-back.
Shiso is a tender annual, ensure temperatures are mild enough to transplant and wait until after your last frost date.
Harvest leaves any time after plant is a few inches tall, but before it flowers. Flowers are also edible and delicious in salads.
