A Really Useful Green Liquid Fertilizer

Fill a bucket with fresh, roughly chopped comfrey leaves. Pour boiling water over the leaves to wilt them. Top up the bucket with cold water and loosely cover. A black plastic rubbish bag is idea. Do not use a tightly fitting lid as the gases that form will cause it to explode. Store for about 4 weeks and then strain. It does stink, so keep it away from your house.
To use, dilute 1 cup in 10 litres of water.
