Hi Christine, It depends on how concentrated you have made the comfrey liquid, but usually about 15:1 to 25:1. However, the simple/foolproof way is to add it to water until the colour is like weak tea (without milk, of course!) That way you can't go wrong.
I use mine on literally everything and use no other type of feed except fish, blood and bone forked into the soil when planting things.
