It’s often cut and dropped next to fruit trees in a forest garden, but also (as i’m currently reading DHL book on Comfrey!) very much appreciated by potatoes, french and runner beans.
In one of his potato trials, wilted comfrey was put in a trench (1 1/2lb per foot) and yields increased to 213 lb comfrey vs, 178lb manure and 194lb compost.
Better yet, he also ran taste tests on the potatoes – out of 28 people, 16 preferred the comfrey grown, 7 the manure, 4 the compost and 1 the chemical(?)
He had some people write in to say that while they didn’t have enough comfrey earlier enough in the season to lay in trenches, they incorporated it in the first earthing up with just as good results.
Perhaps this latter approach fits best with no dig, incorporating the wilted comfrey under a surface mulch at the start or end of the season where you are going to plant potatoes next.
Thanks!
