Hi, I use a comfrey tea for my tomato, pepper and fruit plants. Just cut the comfrey leaves, cut them up and place them in a bucket(with a tight fitting lid) and cover with water. Put on the lid- leave for two to three weeks. By this time the resulting brew smells evil! Strain the leaves keeping the liquid- you can throw the leaves on the compost heap. Dilute the brew down to the colour of weak tea and feed to your fruiting plants.I also use the leaves as a mulch under my raspberry canes.
