Save money and grow healthy plants with home grown comfrey organic plant food.
Comfrey is an excellent plant to grow in all but the very smallest organic garden. This perennial plant has a long root that draws plant nutrients up from the subsoil, making these same nutrients available in their fast-growing leaves.
Organic gardeners harvest the leaves around three times a year, cutting them off close to the ground, beginning with a first cut in late spring. The leaves are then used as an organic fertilizer, either directly as a mulch on the surface of the soil, or as a liquid feed.
Prepare a weed-free bed in the late spring, or early summer. Take care to remove all perennial weeds. Plant comfrey offsets (also known as root cuttings) around 24 inches apart. If you leave the soil between the offsets bare then you must weed regularly to allow the plants to establish. To reduce weeding in the first year apply mulch between the plants, either organic mulch such as dried leaves or lawn clippings, or polypropylene weed control matting.
The best variety of comfrey for use in the organic garden is the cultivar developed but Lawrence Hills, founder of the UK organic gardening association “Garden Organic”. Known as “Bocking 14” after the research station where it was developed, this variety of comfrey has leaves particularly rich in nutrients, and it does not set seed easily, reducing the risk of it spreading around the garden.
The leaves can be used as nutrient-rich mulch that rots down quickly into the soil, releasing valuable plant food. Wilt the leaves for a day or so before applying to ensure they do not take root. There is no need to apply a heavy mulch, a thin layer of leaves is all that is needed.
There are two ways to make liquid comfrey food for plants:
