>> Good luck with the fertilizer! I am unfamiliar with this kind but definitely intrigued.<<

You can make liquid fertilizer from various plant or animal parts that are high in nutrients. Comfrey is what permaculture calls a "miner" plant, which means it sinks deep roots into subsoil and drags up minerals and trace elements to deposit in its leaves. So you can compost the leaves to get the nutrients, or in this case, rot them down to make liquid fertilizer.

I've gotten a few strawberries, but the birds are getting some too.
