You'll want to ask that question in the Soil, Compost and Mulch forum

I don't go into all that trouble of brewing tea. However, I used the leachate I collected from my FT that pooled in the chamber during winter. I suspect it's not just leachate but condensation and dead worms also. I used it only for outdoor plants and I noticed this real skinny Rhododendron that just wouldn't do well before. Truth be told, I didn't even dilute it, just dumped (not just once) on the ground. Come spring, it turned into a lush bush and flowered.

When I need to throw out any product the worms produced, I "throw" them out in the garden. Like clumpy VC and VC that dried out, mixed them under bushes and plants in the garden.

I saved worm tea from the worms I had at my old house, and it was in our storage unit for quite a while. Pulled it out when we were having a major whitefly problem down here, diluted it and used it on my son's ficus hedges that were just being sucked dry by whitefly, and on the yard. 2 sprayings about a month apart and no more whitefly problems for almost a year. The hedges came back great. I don't think I would use it on edibles though, unless there was plenty of time before harvesting.
