Comfrey Growing Instructions
Comfrey leaves are an extremely good organic source of potassium. It’s roots go down very deep into the soil which gives it access to minerals, out of reach to most garden plants.
A Comfrey bed will remain productive for 20 years and can be difficult to irradiate once established, so it is important to choose your site carefully.
It should be grown in full sun away from hedges. Before planting dig in a good helping of manure and remove all perennial weeds. Plant root sections 5 cm (2 inches) deep and 60 cm (2 ft) apart. Plant sections horizontally as it can sometimes be difficult to tell which end will be the growing point!
Keep well watered while plants are becoming established. In the first year cut the foliage 5-cm (2 inches) above the ground with shears in July to prevent it from flowering. Then leave it to grow until it dies down in October. In subsequent years it can be cut approximately every six weeks. With the first cut in April and the last in late September.
Apply a top dressing of manure before growth begins again in the spring, even fresh poultry manure can be used!
