A question from Kobus:
I recently bought a worm “farm”, which works very well.
The seller told me I can use the “worm pee” for my garden, diluted
1:20, but I cannot find literature to back this up, even on this
Is this true and can you please direct me to more information?
In all honesty, there isn’t such a thing as “worm pee”. Earthworms do not urinate like mammals. I have encountered people using that term to refer to “worm tea”, however.
The term “worm tea” is often used to refer to the leachate (drainage liquid) that seeps out from the bottom of vermicomposting system (obviously, only those systems with holes in the bottom). It CAN be used as a liquid fertilizer of sorts, but it’s quality will depend on the maturity of the vermicomposting system (and how well it has been maintained).
Generally, the older the system, the more vermicompost will have been deposited in it, and therefore the closer the drainage liquid will be to actual “vermicompost tea”. The leachate from newer systems, and those that are poorly maintained can contain various phytotoxic compounds, so it’s important to be a bit more cautious when using it. Diluting it and/or aerating before use can help though.
My personal preference is to focus on creating high quality vermicompost FIRST, and then to make a “tea” using that.
Hope this helps!
