Do you own a Wriggly Wranch Worm Bin or a worm bin in general and wonder what the liquid that forms in the bottom tray is? It is worm tea, sometimes it is also called "worm castings tea" or "vermiwash." You may not be aware, but there are numerous benefits of using worm tea in your soil. Worm tea is a natural fertilizer which is used to promote the growth of plants. If you own a Wriggly Wranch bin, worm tea forms in the bottom tray that can be drained from the spigot. If you are a gardening enthusiast, you can use worm tea to replenish the soil with nutrients and protect plants from many plant diseases. 

Worm tea has the same benefits as worm castings, but in liquid form. Castings, also called "worm manure" or "worm humus", are produced when worms break down the organic matter in the soil. These castings are present in the worm beds. When you run water through these castings, nutrients such as nitrogen, calcium and magnesium are picked up. The process of harvesting worm castings is called "vermicomposting."   

How to Make Worm Tea

For making worm tea, you will need a large bin or worm compost bin, such as the Wiggly Wranch bin.The bottom tray should have a drainage spout and holes for aeration. Soak a handful of worm castings in at least 5 liters of warm water. Allow the castings to soak for a couple of days. Next add a teaspoon of molasses (optional). Molasses will promote the growth of micro-organisms. If you feed your worms a balanced diet such as fruits and vegetables (no meat or dairy) they will produce the best castings and worm tea.
