Ingredient Series 3: Comfrey


We have our own Comfrey nursery (raised garden in pic 1 and paper-pot root cutting propogation pic 2) and are planning wide scale planting of this awesome plant to add to our composts and of course supply the Kinatonic range.

Comfrey is a particularly valuable source of fertility to the organic gardener. It is very deep rooted and acts as a dynamic accumulator, mining a host of nutrients from the soil. These are then made available through its fast growing leaves (up to 4-5 pounds per plant per cut) which, lacking fibre, quickly break down to a thick black liquid. There is also no risk of nitrogen robbery when comfrey is dug into the soil as the C:N ratio of the leaves is lower than that of well-rotted compost. Comfrey is an excellent source of potassium, an essential plant nutrient needed for flower, seeds and fruit production. Its leaves contain 2-3 times more potassium than farmyard manure, mined from deep in the subsoil, tapping into reserves that would not normally be available to plants.
