Goodness from weeds

Dandelions have a long taproot which absorbs many minerals from the ground, particularly potassium and magnesium. Though often unwelcome in the garden, they can be used in a rich, simple fertiliser. After lifting, the flower, leaves and root are stored in a bucket. The plants are packed tightly and when the bucket is two thirds full, are weighed down with a brick or rock. The bucket is then topped up with rainwater and covered with a loose-fitting lid or mesh to keep out flies and capture the pungent smell. The mixture will ferment, creating carbon dioxide, so an airtight lid is not recommended. It is then left for a minimum of three days and a maximum of two weeks. Before using, it should be strained to remove any seeds and diluted to one tenth of its strength. Other weeds, such as nettles and horsetail, can also be included.
