If you plan on having animals like chickens and goats, the comfrey is very healthy for them...High in protein from what I have been told.... I plan on making square beds around all my fruit trees and planting comfrey in the beds under the fruit trees... then when they get to a good size, I will allow the goats to munch on them a bit every day... I know I cant allow the goats to have full access to my fruit trees, but will allow them some time to eat the comfrey and hopefully keep some of the grass cut in that area....A friend of mine uses the comfrey for her salads, because of the high protein in it.
