How to Grow and Care
Comfrey can be grown from seed, but it requires a winter chilling period to germinate. If all you want is one plant, you can usually find them for a reasonable price in the herb section of local nurseries or by mail order. Plants can go outdoors once the danger of frost has passed.
When starting several plants, it is more common to use root cuttings. These are 2 to 6 inches (5 to 15 cm) lengths of the root which are planted horizontally 2 to 8 inches (5 to 20 cm) deep. Plant shallow in clay soil and deeper in sandy soils.
You can also grow Comfrey from crown cuttings, but these will be more expensive. A crown cutting will include several eyes and may grow faster than root cuttings, however, the difference is negligible. Crown cuttings are planted 3 to 6 inches (7.5 to 15 cm) deep.
Comfrey is widely adapted but it will thrive in a rich organic soil… – See more at: How to Grow and Care for Comfrey.
