I have been using worm castings for decades, ever since I found out how fantastic they are. I did a bunch of research on them long ago. They do not need to be composted. They can be used in several ways. You can just spread them on the soil and water them in or dig them in. You do not need to make a tea, with or without extra stuff like molasses. The reason to do that is to increase the number of bacteria, enzymes, etc. Which is great but not necessary. I have worm bins to which I add plant material for them to eat. It takes months to get a big load of castings but if you get the commercially made bins (rather than the home made ones) there is a lower area to collect liquid and a spigot. The liquid forms continuously and you can collect it anytime you want some, then dilute it and either add it directly to the soil of filter and spray it on the plants and soil. When I had a small backyard nursery with thousands of plants this was almost all I used and for fertilizer and the plants were fantastic. Now I have a backyard with tons of veggies, fruit trees, and ornamentals and it works great for keeping everything healthy and happy but I do use a little extra fertilizer for some things because I plant so intensively. . At the price you are getting them, I wouldn't care about going to the trouble of making a special tea! That is a fantastic price, even if it has some bedding material. If it is straight castings it will look like black dirt but lots of tiny little grains. If it has bedding material in it, it will look more like compost, which it kind of is! The reason it's so great is that as the worms eat plant material, tiny bugs, etc they leave behind a fantastic collection of bacteria, fungi nutrients and enzymes. Like most manure but better. They also have an enzyme in their gut called chitonase which is to break down the chiton in the outer shell of many tiny bugs. Some of this chitonase is in the castings and is absorbed by the plants and helps to kill small sucking insects that attack your plants. So the castings also act as a systemic insecticide. Worm castings work better at getting rid of white fly than anything else ever did, seriously! It is also a mild fungicide. If you spray it on the plants it is absorbed thru the leaves, like foliar feeding. And some will drip to the ground also. The castings feed the soil more than the plants, because of all the good stuff in it. The soil then feeds the plants and makes them stronger and healthier. I have seen some results that can only be described as miraculous. I am an all organic landscaper and I use worm castings at all my clients houses, on everything, with great results. I really encourage everyone to try them!
