the organic garden
I use a drum with a lid and half fill it with harvested comfrey leaves. Then top with water and replace the lid. leave stewing for about 2 weeks, giving an occassional stir and topping with water if needed. to use - I skim the water off the top and then use a 50/50 mix for established plants...make it a little weaker for seedlings. Comfrey is also a good bug deterrent and also a great foliage spray. Plus its organic !!!!
