Comfrey is ideal for making a powerful liquid feed as it contains the 3 vital elements, Nitrogen, Potassium and Phosphorous that are essential for healthy plant growth.
I grew these First Earlies last year. They grew really quickly and provided our family with copious amounts of very tasty new potatoes. I left a few plants in and was still diving nice larger potatoes in early july. Going to order some more for 2013.
