Worm compost tea vs. worm bin drainage

If you're reading my blog, then you probably know that worm compost tea is great for your plants. I want to make a distinction though: worm compost tea vs. worm bin drainage.

In my mind, worm compost tea is distinctly different from the liquid that drains from some bin designs (what I call worm bin drainage).

Worm compost tea is made by separating the vermicompost from the worms and steeping the worm compost in water to make a tea. My website has complete instructions for brewing up your own worm tea: 1# of vermicompost in a 5 gallon bucket of water.

I don't mean to say that the drainage from a worm bin would be bad for plants. From what I have read it is great fertilizer; however, I'd be concerned about putting it on edible veggies because you do not know what is in it. I have also found a variety of different reports on how to use it ranging from straight (undiluted) to diluted to the color of straw. If I were to use this on salad and other greens I probably diluting it to straw color and bubbling air through it for 12-24 hours using an aquarium bubbler.

If anyone has experience using worm bin drainage, I'd love to hear how you prepare it for use.

The effect of worm compost tea on Amaryllis

Hypothesis: The Amaryllis that receives worm tea weekly will do better than the one receiving just water.

Methods: We started with 2 identical Amaryllis hippeastrum bulbs. One was watered with worm tea, the other was watered with tap water. Both were planted according to package instructions and were placed on a south-facing window side-by-side. We documented growth for 1.5 months. Start 2/14/09

Results: The Amaryllis receiving worm tea grew faster, bloomed faster and the bloom lasted longer than the one receiving just tap water. Yes, our plant with the worm tea had 2 blooms, but I think that was just chance.

The photos tell it all. Try making some worm tea for your indoor plants.

Seasonality of worm compost tea

I am fascinated by making worm compost tea. When we have a rainy stretch, I make it almost every day and sprinkle it all over my yard and garden. I tend to give a little extra to my tomatoes, peppers and blueberries this time of year, hoping for big returns.

I make my tea using the same simple recipe on my website, yet at different times of the year I get very different results. Not just color, but smell. I realize the many variables that could contribute to this-- compost, temperature, the content of my rain water. I often wonder whether different batches are more or less alive and how the nutrients differ among them. If any of you have noted the variability or done any testing, let me know. I am not so much concerned as I am curious.

Also, I'm using a new bubbler this year. I switched to a sandstone bubbler instead of the foam wire. While I don't think I'll ever get the sandstone white again, I am confident the vinegar kills whatever is on it. Unlike the foam bubbler (which I wrapped around my bag) I have to tie it to my compost bag with jute because it floats. In any case, it makes lots of bubbles. The main reasons I switched were the price and concerns over foam rubber and plastic.
