If you are familiar with Permaculture you will hear many many references to using Comfrey as a companion plant in your plant guilds. This fast growing plant is impossible to get rid of once it is established so make sure you really really want it in that area your going to plant it. This deep tap root plant mines for water and minerals. It grows fast, gets tall, topples over and does it all over again. You can also chop and drop it as a mulch to get more plant material down on your beds fast. The plant will regrow.
Well like so many things you hear that your supposed to use something like this, but there is rarely any evidence to back it up. Mostly rumors, wives tales, and stories and rarely do you get data. Well someone agreed that there should be some data to back this story about comfrey up so someone tested it.... I think you will enjoy it.
If you want to know more about the uses of comfrey we will talk about tree guilds soon as we will be planting a lot of trees this year. Comfrey will certainly be in the mix here!
