I didn't want all those leaves to go to waste if I could make tea from them.
THAT WOULD BE ALLOT OF TEA..MOST PEOPLE RAISE COMFREY FOR GARDEN FERTILIZER...CUT IT 5X YEARLY AND SPREAD ON THE GARDEN.
I will cut my plant down and dry the leaves. I should have a lot of tea for winter time as my plant is about 4 ft now and as you say will grow several times through the summer. It looks so nice in my garden. I will check out the root process as well. I thought if I took out the root I would kill my plant so will check it out when I cut it down.
ONCE THE COMFREY PLANT IS ESTABLISHED, YOU CAN'T KILL IT. IF YOU ALLOW IT TO SEED DOWN, PLANTS WILL POP UP 100 FEET AWAY.
