Dry, composted Comfrey has an N-P-K of about 0.25 - 0.25 - 1.5. The potash content is about half that of dry, composted alfalfa which is 2 - 0 - 3. Comfrey has the advantage that it has a much longer life span and much greater output per shrub than alfalfa. The seeds are invasive, so take care when it flowers. As the sole source of potassium for a fruiting banana, use 60 to 100 pounds of dry composted Comfrey leaf per year.
