Comfrey is a fast-growing, deep-rooted perennial herb known for its ability to improve soil health and support garden ecosystems. Its deep taproots mine nutrients from the subsoil, bringing them to the surface, making comfrey an excellent natural fertiliser. The leaves are commonly used as "green manure," compost activators, or mulch around other plants to promote growth.

Comfrey also has a long history of medicinal use in traditional remedies for skin healing and reducing inflammation, although internal use is now discouraged due to its pyrrolizidine alkaloid content.

Comfrey pairs well with fruit trees, tomatoes, and potatoes, providing a boost to their growth while improving soil structure and retaining moisture.

Where Can You Grow Comfrey

Comfrey thrives in a wide range of climates, including Zones 3-9. It prefers well-draining soil and full sun but can tolerate partial shade. Once established, it is drought-resistant and can grow vigorously, even in less-than-ideal conditions.

History and Historical Uses

Comfrey has been used for centuries, both in agriculture and medicine. Originating in Europe and Asia, it was traditionally referred to as "knitbone" due to its use in poultices to aid in bone healing and wound care. In modern gardening, it is prized for its regenerative properties and role in permaculture systems.

Canadian Zone Information

  • Zones 8-9: Plant root stock in early spring or autumn for the best results.
  • Zones 5-7: Plant in spring after the ground thaws or in early autumn to establish before winter.
  • Zones 3-4: Mulch heavily after planting to protect roots from freezing temperatures.

How to Grow and Propagate

  1. Planting: Choose a sunny or partially shaded spot with well-draining soil. Dig a hole deep enough to accommodate the root stock, place it in the hole with the crown just below the soil surface, and cover with soil.
  2. Watering: Water well after planting and keep soil consistently moist during the first few weeks.
  3. Maintenance: Once established, comfrey requires minimal care. It will grow vigorously and can be cut back multiple times during the growing season.
  4. Propagation: Divide established roots in early spring or autumn to create new plants.

Seed Saving Tips

Comfrey is most commonly propagated by root division due to its limited seed production. However, if seed saving is desired for certain varieties, follow these steps:

  1. Allow Flowers to Mature: Let the comfrey plant flower fully. The seeds will form after the flowers fade.
  2. Allow Seeds to Mature: Monitor the flower heads as they dry. Once the seed pods are brown cut them low at the stalk. Tie them in a brown paper bag to hang and dry-down in a shaded but warm spot.
  3. Separate Seeds from Chaff: After drying down rub the seed pods to extract the seeds and clean them with a sieve or by blowing gently across the seed whilst in a shallow bowl
  4. Dry and Store: Spread seeds on a clean surface and allow them to dry in a cool, airy space for 1-2 weeks. Store in an airtight container in a cool, dark place. Properly stored seeds remain viable for up to 2 years.
