Just tried to post this question but it doesn't seem to be showing up so I'll try again.

When I have loads of comfrey leaves I will sometimes steep them in a bucket of water for a few weeks to create a liquid fertilizer. I don't aerate the mix - just allow plenty of time for the leaves to break down, then strain out any remaining solids and store the liquid in plastic 1 gal. milk containers.

My question is how long will the liquid remain useable as a fertilizer? Are all of the minerals leached (hopefully) from the leaves still be present in the liquid after weeks or months of storage or do they somehow dissipate or alter to a different form?

Do any of you make a similar concoction or have any information on the subject?

thanks,

Harry
