No, not that kind of tea! It’s time for vermicompost tea! Many gardeners know the benefit of fertilizing plants with compost tea or as we like to call it, liquid organic fertilizer. Making worm tea, just like composting can be as complex or simple as you want. You can use a bucket or a thousand dollars worth of equipment, it all comes down to the bacteria, doesn’t everything…
The idea behind tea made from worm cast is the promotion of healthy aerobic bacterial growth along with the readily soluble macro/micro nutrients found there in. As in all of nature the balance between aerobic and anaerobic bacteria really dictates the health of your soil and plants. http://www.naturesperfectplantfood.com/2013/06/11/probiotics/ As we know, vermicomposting is the employment of worms to compost organic material, the worms rely on aerobic bacteria to fulfill this mandate. In turn you can use “brewing” methods to promote this bacterial growth and boost the “good” bacterial content of your soil.
The simplest way to “brew” compost tea is to mix one part worm cast to nine parts water, let stand for 8-10 hours and water your garden. If you leave the mixture longer, the aerobic bacteria will drown and the concoction will become septic. Still effective as a source of nutrients but benefits of aerobic bacterial content will be lost. Commercial brewing systems often have a mechanism for aeration to prevent anaerobic conditions from developing. You may also rig up your own aeration to keep the bubbling going but be aware, you need a lot of bubbles. One 5 gallon pail (20L) would require at least two fish tank aeration hoses to maintain a high enough oxygen content.
The end point here is that no matter how you make it, worm tea will fertilize and enrich your soil and plants in a way that nothing else can. Give it a go!
