Debunking the "Worm Wees" Myth

Every time we strike up a conversation around our worm farming practices, folks will excitedly tell us about how keen they are for some "worm wees" and we then educate folks on how worm farms work and what liquids can come from worm farming, which ones are good, and which ones are not.

Worm Wees

Right up front, let's clear this up - there is no such thing as worm wees. Worms do not urinate, and (we've checked) they don't have the equipment to do so! It's not a thing. What you might be thinking of is probably one of the two things below.


When you refer to "worm wees" you might be referring to the dark liquid that come out the bottom of your worm farm. Let's be clear about this: There should not be liquid coming from the bottom of your worm farm. If there is, it is most likely due to one of two things:

You may be over feeding your worm farm. When this happens the waste in your worm farm rots (instead of decomposing) which creates a dark liquid known as leachate. This liquid is normally dark, anaerobic, and can contain pathogens which can be harmful to your worms, your garden, your pets, and you. Some times it isn't, and it can be amazing for your garden. The problem is you don't know which it is, and there is no way of knowing unless you have it tested.

By putting this on your garden, you are playing russian roulette with your plants. You might be giving them amazing nutrient rich liquids, or you might be killing them. The golden rule if you are determined to put this liquid on your garden is: don't put it on anything you're not willing to lose.

If you are getting this liquid out the bottom of your farm, stop feeding your farm for a while, remove the rotting top layer from your farm and then once things settle down, gradually introduce food back into the mix.

Another cause for liquid coming from your worm farm is that it may be too wet. Your worm farm should be moist, but NOT wet. If you grab a handful of material from your farm, and squeeze it in your fist, a couple of drops of water should come out from between your fingers, but no more. NEVER directly spray your worm farm with water - that is way too much water for the farm and will just run through and drain out the bottom. Apply water (if needed) to your farm using a mister.

Worm Tea

Now on to the good stuff. 

If you take some vermicast, and steep it in NON Chlorinated water (Ideally while bubbling air through it), you will create Worm Tea. This is the really good stuff which can be diluted and sprayed on to your garden. Some folks also add molasses to encourage microbial populations in the worm tea, but we do not recommend this. Worm Tea is an excellent way to get the most out of your vermicast; try making some yourself and see for yourself the awesome benefits that adding worm tea to your garden can deliver.
