Description: These are Bocking 14 Crown cuttings, which are much easier to grow when compared to root cuttings. Comfrey has long been recognized by both organic gardeners and herbalists for its great usefulness and versatility; of particular interest is the "Bocking 14 and Bocking 4" cultivars of Russian Comfrey. These strains were developed during the 1950s by Lawrence D Hills, the founder of the Henry Doubleday Research Association (the organic gardening organisation itself named after the Quaker pioneer who first introduced Russian Comfrey into Britain in the nineteenth century) following trials at Bocking, near Braintree, the original home of the organization. The comfrey bed should be well prepared by weeding thoroughly, and dressing with manure if available. Offsets (crown cuttings) should be planted 0.6?1 m (2 ft 0 in?3 ft 3 in) apart with the growing points just below the surface, while root cuttings should be buried about 5 cm (2.0 in) deep. Keep the bed well watered until the young plants are established. Comfrey should not be harvested in its first season as it needs to become established. Any flowering stems should be removed as these will weaken the plant in its first year. Comfrey is a fast-growing plant, producing huge amounts of leaf during the growing season, and hence is very nitrogen hungry. Although it is a tenacious grower, it will benefit from the addition of animal manure applied as a mulch, and can also be mulched with other nitrogen rich materials such as lawn clippings, and is one of the few plants that will tolerate the application of fresh urine diluted 50:50 with water, although this should not be regularly added as it may increase salt levels in the soil and have adverse effects on soil life such as worms. Mature comfrey plants can be harvested up to four or five times a year. They are ready for cutting when about 60 cm (24 in) high, and, depending on seasonal conditions, this is usually in mid-Spring. Comfrey will rapidly regrow, and will be ready for further cutting about 5 weeks later. It is said that the best time to cut comfrey is shortly before flowering, for this is when it is at its most potent in terms of the nutrients that it offers. Comfrey can continue growing into mid-autumn, but it is not advisable to continue taking cuttings after early autumn in order to allow the plants to build up winter reserves. After the growing season, leaving comfrey beds fallow may deliver higher yields in future harvests, as the plant builds up energy reserves in its roots. Comfrey should be harvested by using either shears, a sickle, or a scythe to cut the plant about 2 inches above the ground, taking care handling it because the leaves and stems are covered in hairs that can irritate the skin. It is advisable to wear gloves when handling comfrey. Despite being sterile, Bocking 14 Russian Comfrey will steadily increase in size. It is therefore advisable to split it up every few years. It is however difficult to remove comfrey once established as it is very deep rooting, and any fragments left in the soil will regrow. Rotovation can be successful, but may take several seasons. The best way to eradicate comfrey is to very carefully dig it out, removing as much of the root as possible. This is best done in hot, dry summer weather, wherein the dry conditions will help to kill off any remaining root stumps. Comfrey is generally trouble free once established, although weaker or stressed plants can suffer from comfrey rust or mildew. Both are fungal diseases, although they rarely seriously reduce plant growth and thus do not generally require control. However infected plants should not be used for propagation purposes. Comfrey is a particularly valuable source of fertility to the organic gardener. It is very deep rooted and acts as a dynamic accumulator,[6] mining a host of nutrients from the soil. These are then made available through its fast-growing leaves (up to 1.8?2.3 kilograms (4.0?5.1 lb) per plant per cut) which, lacking fibres, 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, seed 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. There are various ways in which comfrey can be used as a fertilizer. These include: Comfrey as a compost activator ? include comfrey in the compost heap to add nitrogen and help to heat the heap. Comfrey should not be added in quantity as it will quickly break down into a dark sludgy liquid that needs to be balanced with more fibrous, carbon-rich material. Comfrey liquid fertilizer ? can be produced by either rotting leaves down in rainwater for 4?5 weeks to produce a ready-to-use "comfrey tea", or by stacking dry leaves under a weight in a container with a hole in the base. When the leaves decompose a thick black comfrey concentrate is collected. This must be diluted at 15:1 before use. Comfrey as a mulch or side dressing ? a two-inch layer of comfrey leaves placed around a crop will slowly break down and release plant nutrients; it is especially useful for crops that need extra potassium, such as fruit bearers but also reported to do well for potatoes. Comfrey can be slightly wilted before application optionally but either way, avoid using flowering stems as these can root. Comfrey as a companion plant for trees and other perennials ? soil tests confirm that soil nutrients increase in the presence of comfrey even when it is not used as mulch, side dressing, or liquid fertilizer, but just allowed to grow. Comfrey potting mixture ? originally devised to utilize peat, now environmental awareness has led to a leaf mold-based alternative being adopted instead; two-year-old, well decayed leaf mold should be used, this will absorb the nutrient-rich liquid released by the decaying comfrey. In a black plastic sack alternate 7?10 cm (2.8?3.9 in) layers of leaf mold and chopped comfrey leaves. Add a little dolomitic limestone to slightly raise pH. Leave for between 2?5 months depending on the season, checking that it does not dry out or become too wet. The mixture is ready when the comfrey leaves have rotted and are no longer visible. Use as a general potting compost, although it is too strong for seedlings.
