When to Plant Angelica Seeds
Refrigerate Angelica seeds before sowing into the garden or start them in flats. Seeds must be cold stratified, so indoor plantings must be exposed to cold temperatures of 39 degrees or below for 3 weeks warming up in order to germinate. When sown into the garden, plant either before the first frost or after the last frost of the season.
Where to Plant Angelica Seeds
Plant Angelica in prepared garden beds that are nutritious, slightly acidic, with moist to wet soils with exposure to full sun (6-8 hours of sun per day) to partial sun (4-6 hours of sun per day). Do not allow the soil to dry out. Despite the need of sunlight, Angelica performs better when not exposed to the full heat of the evening sun and prefers the morning and noon sun, as it is less harsh.
How to Plant Angelica Seeds
While not required, Angelica seeds can benefit from special 4 to 8 week treatment called cold stratification prior to planting them. Learn more about the importance and process of cold stratification here.
Angelica seeds require light to germinate, so be careful not to cover them when planting. Learn more about germination light requirements here.
Bury Angelica seeds in the surface of the moistened soil no deeper than 1/4th of an inch, and do not cover, as light is required for proper germination. Keep germinating seeds moist. Space seedlings approximately 12-24 inches apart.
How to Harvest Angelica
Leaves and stems of Angelica are edible, and can simply be cut from the plant or pulled up entirely. Roots and seeds are often used for making herbal teas. Be sure to trim back flower heads and seed pods when harvesting for the leaves, as when the plant goes to seed, it will often die.
