Direct sow symphytum seed outdoors from March to June in moist, fertile, well drained soil in a sunny position. Sow seed thinly at a depth of 1cm (½in) in rows 30cm (12") apart. When large enough to handle, thin seedlings to 60cm (48") apart. Alternatively sow Comfrey seeds in pots or trays under glass and transplant them outdoors when plants are well grown.
To harvest, cut the foliage back to about 15cm 6" above ground level with a pair of shears. Comfrey foliage can be harvested 3 or 4 times throughout the summer. Apply a mulch of well rotted farmyard manure to the comfrey patch in spring and lift and divide overcrowded clumps to maintain their vigour and produce new plants.

Caution: Comfrey is harmful if eaten. Contact with the foliage may irritate the skin and eyes. Use gloves when harvesting.
