Comfrey is an esteemed herb in any Permaculture garden, attracting pollinators and beneficial insects, providing medicinal value and enriching the soil with a vast array of nutrients. This incredible herb has three times more potassium than regular manure tea and it’s high in calcium, phosphorus and nitrogen, which are essential for vegetables and fruit bearing plants. It’s the perfect companion for any food garden.
Comfrey is a vigorous growing hardy plant, spreading up to 50cm wide, growing in full to partial sun. It dies back a little in the colder Winter months, re-shooting itself in Spring. In warmer climates it will rarely flower, because it needs the Winter cold spell, and it won’t die back as harshly, making the leaves available all year round.
Divide the roots of young plants in the spring as the new leaves begin to show. Dig them up and separate the roots with a shovel or sharp knife and replant.
Comfrey is a fast growing and the leaves can be harvested up to 6 times a year, starting mid-spring. Cut the leaves back to about 5cm above the soil. Harvest every 6 weeks until early autumn and then leave your Comfrey plants to build up reserves for Winter.
Dry the leaves thoroughly in single layers on a dry rack and then store them in airtight glass jars. Roots can be washed with cool water, cut into thin slices and then dried. They can then be stored as is or ground into a powder.
