Plant history & use:
True Comfrey has historically been a well-used plant in the treatment of various ailments. But above all, it is a very effective accumulator of nutrients, meaning a good soil improver. Comfrey grows quickly and its roots are deep-reaching, giving the plant access to nutrients from deeper soil layers that are otherwise inaccessible to most plants. It is mainly minerals such as potassium and calcium that are stored in the leaves, but also magnesium, iron, phosphorus, manganese, and others.
The leaves of comfrey can be cut down during the year and used as mulch, or alternatively dug into the soil, to make the nutrients available to other plants. Comfrey leaves are well suited as fertilizer for fruit trees and berry bushes thanks to their content of potassium and phosphorus.
Comfrey has a long growing season, from early winter to late autumn.
If the leaves are not cut down before winter, they wither and similarly provide a nutrient boost to the soil they grow on. New leaves begin to grow on the plant immediately after the snow melts.
You can also make your own liquid fertilizer from comfrey by filling a container with the leaves and then filling it with water to the brim. Let it stand for a couple of days and then mix the fertilizer water with 10 parts water to water the plants with.
Effective as an edge plant by manure heaps to prevent nutrient leakage, but also as an edge plant around crops and other places where you do not want weeds to spread. Comfrey’s dense root system acts like an underground wall, making it difficult for other roots to penetrate.
Comfrey creates an attractive environment for other plants in the cultivation – whether it is to attract pollinators or to serve as a natural fertilizer.
Cultivation:
Comfrey is a herbaceous perennial. It thus remains in place even after the leaves have withered during winter.
It is an incredibly easy-care plant and tolerant in choice of growing place. It can grow in shade as well as wet ground and is therefore an effective component in flooded and waterlogged soils.
It also thrives well in drier soils in sunny places, although it prefers a somewhat moist environment.
Sowing:
Sow indoors or outdoors.
If germination has not occurred after one month when sown indoors, place the sowing in the fridge for a month and then bring it back to room temperature, or alternatively place it outside during spring and summer.
Can also be sown outdoors in autumn to give the seeds a “real winter.” The seeds then germinate in spring.
