We had been meaning to make worm tea to apply to our garden. Well, we got some accidentally. We must have been making the smoothies we feed to our worms with more water than usual, because the tray that catches extra water had a lot of brown liquid in it, when usually it is dry. I guess that's a nice feature of our wooden worm bin--it self-regulates if it gets too wet.
I wonder about worm tea vs. directly applying worm castings. Castings are easier, and probably slower-reacting, but can introduce seeds.
