I've heard various good things about seaweed extract,
specifically as a foliar spray.
We're based at the coast, and every once in a while a
large quantity of seaweed washes up on the beach. I've
been collecting it to add to compost, but I'd like to
try the foliar method. How do I prepare the extract?
Just soak the seaweed in water? Make a tea by heating
it?
