A frequent question I get is how to store worm castings.The short answer is : the same way you keep a worm bin.
Worm castings are alive. They contain live microbes and in order to keep them alive you must keep them moist, cool and fed. When I harvest my castings I usually keep them in either a 35 gallon drum or in 5 gallon buckets. Whatever the container there are some rules to follow:1. The container must have air holes
2. The container is best if opaque not clear
3. Keep the contents moist. (once a week dampening usually works)
4. Top feed to wrangle up any worms or babies that hatchIf you follow the above steps, the castings will keep and be active for up to a year or more. Honestly, I have not let mine go longer than a year. Mine are usually used within 4-6 months.
Here is a video on storing worm castings:
What about using the castings? You can use worm compost several ways:1. As a top dressing on any plants and simply water into the soil.
2. As a starter for new plantings (I mix with coconut coir )
3. As worm compost tea (my personal favorite way to use them)
Simple, it works like magic AND makes the castings go much much further.You can take 2 cups of castings and make enough liquid tea to fertilize and nourish your entire yard, grass included. So now the question, how do you make compost tea? Follow this link to go to my article on making compost tea. Or buy yourself a tea brewer like this one if you are not interested in the do it yourself route.
