HARVESTING WORM CASTINGS FROM YOUR BIN

Finished casting with worms 002 (1024x764)This is a standard 38 Litre Rubbermaid bin.  The bin had about 10 cm of worms, eggs and castings covering the bottom.  This bin was “seeded” with only eggs and juvenile worms in May, 2013.  The bedding you see to the right, the castings to the left.  We stopped feeding and watering the bin 3 weeks ago.  This allows time for the worms to complete composting the remaining food material and for the castings to dry out.

Separating worms from castings.Using the “hostile environment” method, you can scoop up a large handful of worms and place them in a well-lit spot inside your home or in the yard.  The trays pictured are large plastic serving trays originally made for food stuffs at celebrations.  Working in small batches can be a little time-consuming, but worms move surprisingly fast.  Leave them for 10 minutes and when you return the worms will have burrowed to the middle of the pile.  Simply scrape off the castings from the surface, take time to look for eggs.  It’s also a good opportunity to remove any white worms you may find. http://www.naturesperfectplantfood.com/2012/12/02/invation-of-the-white-worms/   You can repeat the process a few times ending up with your castings and worms nicely separated.  By “starving” the bin for a week or two, those castings are ready to use in your garden or house plants.  Worms and eggs are returned to the bin to continue doing what they do; composting your food waste into vermicast!
