Yes, fish blood and bone is basically a three month feed but blood is a quick release nitrogen.
I would apply phostrogen when a god few dry hours are likely. Do it when you can. If you apply fish blood amd bone at plantImg time, say early spring, the food should be available from mid summer onward.
A seaweed spray, Epsom salt spray I apply often in the morning on a dry day. (I sense seaweed spray is not liked by slugs....anyone else think this?)
