Growing Guide: Ashitaba
Growing Tips
Also known as: Ashitaba, Tomorrow’s Leaf, Japanese Angelica
Plant Ashitaba (Angelica keiskei) in full sun to partial shade and provide deep, fertile, well-draining soil. This Japanese perennial herb prefers cool conditions and consistently moist soil, so water regularly without allowing the roots to sit in water. Protect plants from intense afternoon heat to encourage healthy leaf growth. Harvest young leaves and tender stems as needed once the plant is established, allowing it to continue producing new growth. Ashitaba can be grown in containers and benefits from regular moisture and occasional feeding with compost or a balanced fertilizer.
