Growing Notes
Part sun to full sun in moist, well-drained ground. Space about 2 feet apart. The siting decision matters more than the growing, because comfrey has a deep, brittle taproot and every fragment left in the ground regrows, so it is close to permanent once planted. Choose the spot carefully the first time.

Maintenance
Cut the whole plant back to the ground two or three times a season for fresh growth; the cut leaves are traditionally used as mulch or a compost activator. Leave at least one flush to flower for the bees rather than cutting it every time. Do not attempt to relocate it.
