Gardening Tip: Home Made Liquid Fertiliser
Comfrey (Symphytum officinale) can become quite invasive and troublesome in the garden.
Make the most of it by picking the leaves, put them in a large container and cover with water. Leave to stew for a few days and then dilute to 1 part stew - to 6 parts water. You now have a useful nitrogen rich home made fertiliser.
