As I continue my journey deeper into veganic gardening, I am perpetually amazed at the wealth of resources present in our own backyard. It seems that anyone with a proper compost pile, a source of mulch or green manure, and common beneficial “weeds” scattered about has all the resources needed to help their garden thrive.
One of my new favorite herbs for the garden, or “weeds”, depending on your perspective, is comfrey (Symphytum officinale), which has a wealth of uses for both our own health and the health of the garden.
Comfrey’s deep roots work to bring nutrients up from the subsoil. These nutrients are then made available in the abundant number of leaves it produces every year (4-5 lbs of leaves per established plant per year). The leaves are rich in nitrogen and potassium with a decent amount of phosphorus as well, making them a wonderful homegrown fertilizer. Researchers in British Columbia analyzed the NPK (nitrogen-phosphorus-potassium) ratio of comfrey and discovered that the leaves have a remarkable NPK ratio of 1.80-0.50-5.30.
